We have studied the long-term memory effects of the Korean agricultural market using the detrended fluctuation analysis (DFA) method. In general, the return time series of various financial data, including stock indices, foreign exchange rates, and commodity prices, are uncorrelated in time, while the volatility time series are strongly correlated. However, we found that the return time series of Korean agricultural commodity prices are anti-correlated in time, while the volatility time series are correlated. The n-point correlations of time series were also examined, and it was found that a multifractal structure exists in Korean agricultural market prices.

Obstacles to Development of Marketing Channels of Agricultural Products in China and Countermeasures

Institute of Scientific and Technical Information of China (English)

2011-01-01

This paper introduces the connotation of marketing channels of agricultural products, and gives an overall of current modes of marketing channels of agricultural products in China, including the marketing channel of transportation and sale of agricultural products, the marketing channel of intermediary sales agent, and the marketing channel of mutual cooperation. The problems existing in the marketing channel of agricultural products in China as follows: first, the cost is high; second, the technological content is low; third, the upstream main body lacks competitiveness; fourth, the structure of investment is irrational. Corresponding countermeasures are put forward to develop marketing channels of agricultural products as follows: perfect the service function of wholesale market of agricultural products; propel the construction of integration and expansion of wholesale market; develop the circulation cooperatives of agricultural products; develop the integrated organization of production and sales of agricultural products.

2011-01-01

Full Text Available The changes in Czech agriculture over the past twenty years have had their impact on the agricultural labour market, too. The regional differentiation of the chances of applicants on the labour market as well as the agricultural enterprises’ chances of hiring employees fitting their requirements, are, among others, influenced by the specific conditions of agricultural production. The aim of this paper pertains to two basic problem areas: first, the differentiation of respective regions based on the number of agricultural applicants and job vacancies, and second, the identification of disequilibrium on the agricultural labour market. The latter is based on a theoretical framework defined by approaches in economy dealing with labour market equilibrium. Due to the unavailability of economic data (including wages, economic performance, etc. on the regional level, authors develop their own methodological approach, based on the number of applicants per job vacancy. A database of applicants and vacancies available from the Labour Offices is used as a source for the analysis and interpretation of data, enabling us to study the agricultural labour market not only sector-wise but also region-wise.

Full Text Available The article is dealing with the market of agricultural machinery with the focus on the loyalty of agricultural subjects. In this market the brand is very important factor that can influence fundamentally the purchaser during buying a machine. Totally there are three types, the subjects that are totally not influenced by the brand mark, the subjects taking in their consideration the brand mark but just as one factor and the rest that is loyalty and buys just one brand. The main objective of this paper is to analyze the customers in this market and their loyalty to each brand. To reach the main goal there were analyzed data of agricultural subject’s facilities, perception of brand marks and their relation. The data were used from own primary marketing research and analyzed by the help of statistics methods for marketing research as a Chi-square test, Pearson product-moment correlation coefficient, Spearman’s rank correlation coefficient and testing the hypotheses. The other part of this paper was focused on the satisfaction of respondents with each brand that they own. According to the article objective there were set hypotheses for following testing that were main mean to solve the goal. The result of this paper is found loyalty for just one brand in the agricultural machinery market. For John Deere brand there was proven the loyalty – subjects perceiving the mark as the best in the market and also buying it. The results can help for our future analyses to understand factors influencing the market and analyses of each brand and how their strategy in the market is conformed to the subject perception and behavior.

The anaerobic digestion of food waste for energy recovery produces a nutrient-rich digestate which is a valuable source of crop available nitrogen (N). As with any 'new' material being recycled to agricultural land it is important to develop best management practices that maximise crop available N supply, whilst minimising emissions to the environment. In this study, ammonia (NH 3 ) and nitrous oxide (N 2 O) emissions to air and nitrate (NO 3 - ) leaching losses to water following digestate, compost and livestock manure applications to agricultural land were measured at 3 sites in England and Wales. Ammonia emissions were greater from applications of food-based digestate (c.40% of total N applied) than from livestock slurry (c.30% of total N applied) due to its higher ammonium-N content (mean 5.6 kg/t compared with 1-2 kg/t for slurry) and elevated pH (mean 8.3 compared with 7.7 for slurry). Whilst bandspreading was effective at reducing NH 3 emissions from slurry compared with surface broadcasting it was not found to be an effective mitigation option for food-based digestate in this study. The majority of the NH 3 losses occurred within 6 h of spreading highlighting the importance of rapid soil incorporation as a method for reducing NH 3 emissions. Nitrous oxide losses from food-based digestates were low, with emission factors all less than the IPCC default value of 1% (mean 0.45 ± 0.15%). Overwinter NO 3 - leaching losses from food-based digestate were similar to those from pig slurry, but much greater than from pig farmyard manure or compost. Both gaseous N losses and NO 3 - leaching from green and green/food composts were low, indicating that, in these terms, compost can be considered as an 'environmentally benign' material. These findings have been used in the development of best practice guidelines which provide a framework for the responsible use of digestates and composts in agriculture.

Digestate from biogas plants can play important role in agriculture by providing nutrients, improving soil structure and reducing the use of mineral fertilizers. Still, less is known about greenhouse gas emissions from soil during and after digestate application. The aim of the study was to estimate the emissions of carbon dioxide (CO2) and methane (CH4) from a field which was fertilized with digestate. The gas fluxes were measured with the eddy covariance system. Each day, the eddy covariance system was installed in various places of the field, depending on the dominant wind direction, so that each time the results were obtained from an area where the digestate was distributed. The results showed the relatively low impact of the studied gases emissions on total greenhouse gas emissions from agriculture. Maximum values of the CO2 and CH4 fluxes, 79.62 and 3.049 µmol s-1 m-2, respectively, were observed during digestate spreading on the surface of the field. On the same day, the digestate was mixed with the topsoil layer using a disc harrow. This resulted in increased CO2 emissions the following day. Intense mineralization of digestate, observed after fertilization may not give the expected effects in terms of protection and enrichment of soil organic matter.

Full Text Available Waste from anaerobic digestion is considered as a mineral fertilizer and it is usually applied to agricultural land. The aim of our attempt was to enrich this waste from anaerobic digestion (digestate with an organic component (in our case represented by haylage. For this purpose, we made different mixtures of digestate and haylage in different weight ratios. In the field trial, the effect of these mixtures on the soil, under standard agricultural conditions, was monitored. Selected accessible nutrients (P, K, Mg, Mn, Ca and the amount of carbon and nitrogen in the soil were monitored. The results of the laboratory tests confirmed that the areas where the sowing and digestate mixtures were applied showed greater amounts of macro- and micronutrients in plant-accessible forms than the surface fertilized only with digestate or areas fertilized only with standard fertilizers.

Emerging as the earliest futures markets, agricultural futures markets play an important role in risk aversion and price discovery. With the integration of global economy, the linkage between domestic and international futures markets becomes closer than ever. By using the thermal optimal path (TOP) method, this paper selects soybean, corn and wheat as the representatives to study the dynamic lead-lag relationship between the Chinese and American markets in both returns and volatility. The results indicate that: (1) For the futures return, different kinds of agricultural futures lead-lag relationship between China and the US varied before 2014 both in direction and order in different time periods. However, China leads the US for all the three kinds we study after 2014. (2) Agricultural commodities subject to less import restrictions and government regulations in China such as soybean are more susceptible to the fluctuations from the international markets. On the other hand, lower foreign trade openness and more government regulation species such as wheat are less affected by fluctuations from outside. (3) The volatility transmission from the US to China wheat futures market takes longer time than soybean, which suggests that China's soybean futures market is more closely linked to the international agricultural futures market than wheat.

Anaerobic digestion of agricultural wastes

Energy Technology Data Exchange (ETDEWEB)

Hobson, P N

1984-01-01

Farm digesters can operate satisfactorily and have a useful role on the farm. Gas production from the farm digester treating animal slurries could be boosted by adding silage liquid, old potatoes, waste cabbages and other crop wastes to the slurry, although the energy economics of maceration have not been calculated. Pollution control and types of digester are discussed. Uses of digested slurry other than for fertilizers are being tested - as protein supplement to farm animal feeds, silage making, hydroponics, fish farming and growing of worms on algae. Overall, digestion could be a contributor to power requirements especially in countries with high all year round crop production.

Experiments have been carried out on the effect of gamma irradiation on total energy, dry organic matter digestibility and on digestible energy of organic matter for some agricultural residues (maize straw, lentils straw, cottonwood, residues of apple-tree pruning, olive-cake first and second treatment). Sample were irradiated at 0, 50 and 100 KGy. Total energy was estimated by calorimeter. Digestibility was estimated in vitro by the method of Tilly and Terry (1963). Two sheep with rumen fistula were used as rumen liquor donating animals. Irradiation resulted in increasing the digestion of organic and dry matter and also the digestible energy of organic matter in all residues used except lentils straw and olive-cake first treatment. The increase in digestible energy values of organic matter (kJ) at dose of 100 KGy were: 155, 105, 71 and 25 for residue of apple-tree pruning, maize straw, cottonwood and olive-cake second treatment, respectively.

Wheat is the primary grain fed to poultry in western Canada, but its nutritional quality, including the nature of its starch digestibility, may be affected by wheat market class. The objectives of this study were to determine the rate and extent of starch digestibility of wheat market classes in broiler chickens, and to determine the relationship between starch digestibility and wheat apparent metabolizable energy (AME). In vitro starch digestion was assessed using gastric and small intestinal phases mimicking the chicken digestive tract, while in vivo evaluation used 468 male broiler chickens randomly assigned to dietary treatments from 0 to 21 d of age. The study evaluated 2 wheat cultivars from each of 6 western Canadian wheat classes: Canadian Prairie Spring (CPS), Canadian Western Amber Durum (CWAD), CW General Purpose (CWGP), CW Hard White Spring (CWHWS), CW Red Spring (CWRS), and CW Soft White Spring (CWSWS). All samples were analyzed for relevant grain characteristics. Data were analyzed as a randomized complete block design and cultivars were nested within market class. Pearson correlation was used to determine relationships between measured characteristics. Significance level was P ≤ 0.05. The starch digestibility range and wheat class rankings were: proximal jejunum - 23.7 to 50.6% (CWHWSc, CPSbc, CWSWSbc, CWRSab, CWGPa, CWADa); distal jejunum - 63.5 to 76.4% (CWHWSc, CPSbc, CWSWSbc, CWRSab, CWGPa, CWADa); proximal ileum - 88.7 to 96.9% (CWSWSc, CPSbc, CWHWSbc, CWRSb, CWGPb, CWADa); distal ileum - 94.4 to 98.5% (CWSWSb, CWHWSb, CPSb, CWRSab, CWGPab, CWADa); excreta - 98.4 to 99.3% (CPSb, CWRSb, CWHWSb, CWSWSab, CWGPab, CWADa). Wheat class affected wheat AMEn with levels ranging from 3,203 to 3,411 kcal/kg at 90% DM (CWRSc, CWSWSc, CPSb, CWGPb, CWADa, CWHWSa). Significant and moderately strong positive correlations were observed between in vitro and in vivo starch digestibility, but no correlations were found between AME and starch digestibility. In

2016-04-01

The aim of this study was to establish sustainably feasible areas for the implementation of anaerobic co-digestion plants for agricultural wastes (cattle/swine slurries and cereal crop wastes). The methodology was based on the use of geographic information systems (GIS), the analytic hierarchy process (AHP) and map algebra generated from hedges related to environmental, social and economic constraints. The GIS model obtained was applied to a region of Chile (Bío Bío Region) as a case study showing the energy potential (205 MW-h) of agricultural wastes (swine/cattle manures and cereal crop wastes) and thereby assessing its energy contribution (3.5%) at country level (Chile). From this model, it was possible to spatially identify the influence of each factor (environmental, economic and social) when defining suitable areas for the siting of anaerobic co-digestion plants. In conclusion, GIS-based models establish appropriate areas for the location of anaerobic co-digestion plants in the revaluation of agricultural waste from the production of energy through biogas production. © The Author(s) 2016.

Paudel, Shukra Raj; Banjara, Sushant Prasad; Choi, Oh Kyung; Park, Ki Young; Kim, Young Mo; Lee, Jae Woo

2017-12-01

The anaerobic digestion (AD) of agricultural biomass is an attractive second generation biofuel with potential environmental and economic benefits. Most agricultural biomass contains lignocellulose which requires pretreatment prior to AD. For optimization, the pretreatment methods need to be specific to the characteristics of the biomass feedstock. In this review, cereal residue, fruit and vegetable wastes, grasses and animal manure were selected as the agricultural biomass candidates, and the fundamentals and current state of various pretreatment methods used for AD of these feedstocks were investigated. Several nonconventional methods (electrical, ionic liquid-based chemicals, ruminant biological pretreatment) offer potential as targeted pretreatments of lignocellulosic biomass, but each comes with its own challenges. Pursuing an energy-intensive route, a combined bioethanol-biogas production could be a promising a second biofuel refinery option, further emphasizing the importance of pretreatment when lignocellulosic feedstock is used.

Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

NETWORKS AND INTERMEDIARIES IN SEASONAL AGRICULTURAL LABOR MARKETS IN TURKEY

Directory of Open Access Journals (Sweden)

Motoi Kusadokoro

2016-04-01

Full Text Available In casual labor markets, intermediaries are used in order to match employers and employees. This function is especially important when the market is imperfect and employers and employees have not formed solid networks. This paper investigates the network effects and the role of intermediaries in the seasonal agricultural labor market in the irrigated area of Adana, Turkey. The network of rural households is divided into one composed mainly of farmers and one composed mainly of seasonal agricultural workers. Our regression analyses show that the seasonal workers who do not have strong networks with farmers have difficulty finding jobs. Middlemen serve to mitigate the seasonal workers’ lack of a network and play a key role in the area’s seasonal agricultural labor market. At the same time, however, blood ties and territorial ties between middlemen and workers may cause middlemen to discriminate among seasonal workers based on their origins.

The Prospects for Development of the Agricultural Land Market in Ukraine

Kushnir Nina B.

2017-03-01

Full Text Available The article is aimed at studying the basic aspects of establishment and development of the land market. A mechanism for securing against the leasehold estate and a model of an agricultural land market have been proposed. It has been specified that the most important component on formation of land market in our State is to work to change public opinion, people attitudes regarding the private ownership of land and deals with it. The proposed mechanism for securing against the leasehold estate has not only economic, but also social significance, which, above all, is that securing against the leasehold estate does not change the owner of the land, and, consequently, does not threaten villagers with dispossession of land. With introduction of the presented model of an agricultural land market it can be argued that such a market is an open, complex system based on the interaction between its actors over the use, disposal and market turnover of agricultural lands.

Agricultural Credit Market and Farmers’ Response: A Case Study of Turkey

Directory of Open Access Journals (Sweden)

Erdogan Gunes

2017-01-01

Full Text Available Agriculture is an important sector in Turkey’s economy. Access to credit financing is critical for timely acquisition of different inputs, farm productivity, and ultimately farmers’ financial well-being. Historically, Ziraat Bank and Agricultural Credit Cooperatives, supported by Turkish government, have been the principle supplier of loanable funds in the agricultural sector. However, since 2000, many private banks have discovered the potential of this market and entered the competition. This study was designed to investigate the structure of the agricultural credit market in Turkey and identify factors that influence farmers’ preference among alternative lenders. It was found that although the 550 Turkish farmers surveyed had several options among lenders, low interest rates and attainable eligibility criteria emerged as the most important differentiators among banks. Results from the Analytic Hierarchy Process (AHP demonstrate the rising role of private banks’ credit. However, Ziraat Banks’ subsidized credits still dominant and its composite weight is 30.74% of total amount of agricultural credit market.

Full Text Available Following the dramatic changes experienced by the prices of agricultural commodities in 2007-2008, the analysis of horizontal price transmission mechanisms in agricultural markets has attracted renewed interest. In particular, this has led to the emergence of new challenges for the empirical analysis. How to model the increasing volatility and non linear behaviour of prices, to assess the impact of the policy responses to market turbulence, and how to account for the increasing interconnections between agricultural and non-agricultural commodity markets are amongst the most investigated issues. Building on a common analytical framework, this paper discusses and reviews the most recent methodological developments and empirical contributions in the field.

2018-01-01

For years, anaerobic digestion processes have been implemented for the management of organic wastes, agricultural residues, and animal manure. Wet anaerobic digestion still represents the most common technology, while dry fermentation, dedicated to the treatment of solid inputs (TS>20%) can be considered as an emerging technology, not in terms of technological maturity, but of diffusion. The first agricultural dry anaerobic digestion plant constructed in Italy was monitored from the start-up, for over a year. The plant was fed with manure and agricultural products, such as corn silage, triticale, ryegrass, alfalfa, and straw. Three Combined Heat and Power units, for a total installed power of 910kW e , converted biogas into thermal and electric energy. The monitoring included the determination of quality and quantity of input feedstocks, of digestate (including recirculation rate), of leachate, biogas quality (CH 4 , CO 2 , H 2 S), biogas yield, energy production, labor requirement for loading, and unloading operations. The results of the monitoring were compared to performance data obtained in several full scale wet digestion plants. The dry fermentation plant revealed a start-up phase that lasted several months, during which the average power resulted in 641kW e (70.4% of nominal power), and the last period the power resulted in 788kW e (86.6% of installed power). Improving the balance of the input, the dry fermentation process demonstrated biogas yields similar to wet anaerobic digestion, congruent to the energy potential of the biomasses used in the process. Furthermore, the operation of the plant required significant man labor, mainly related to loading and unloading of the anaerobic cells. Copyright © 2017 Elsevier Ltd. All rights reserved.

The Mode Reform of Cultivating Marketing Talents in Agricultural Vocational Colleges Based on the Perspective of Agricultural Enterprises——A Case Study of Wenzhou Vocational College of Science and Technology

Institute of Scientific and Technical Information of China (English)

2011-01-01

We conduct survey on the characteristics of demand of agricultural enterprises for agricultural marketing talents from the following 6 aspects:the professional marketing talents needed urgently by the agricultural enterprises,the amount of demand of agricultural enterprises for the marketing talents,the jobs offered by the agricultural enterprises,the educational background of agricultural marketing talents favored by the agricultural enterprises,the requirements posed by the agricultural enterprises on the work experience of agricultural marketing talents,and the quality requirements posed by the agricultural enterprises on the agricultural marketing talents.We analyse the problems existing in the cultivation mode of marketing talents in agricultural vocational colleges as follows:the feature of major is not outstanding;the contradiction between supply and demand is prominent;it is disconnected with the practical needs of agricultural enterprises;the cultivation form of practical ability is simple.On the basis of this,taking Wenzhou Vocational College of Science and Technology as an example,we advance the new mode of cultivating inter-disciplinary talents integrating "marketing technique+technique marketing",and establish characteristic agricultural course combo system on the basis of vocational position orientation.In the meantime,we propose that we should conduct close college-enterprise cooperation with the local leading agricultural enterprises.This cultivation mode reform of talents is favorable for the agricultural enterprises,especially small and medium-sized agricultural enterprises to foster "marketable" agricultural marketing talents,elevate the comprehensive competitiveness of small and medium-sized agricultural enterprises,serve the local economy,and promote the development of modern agriculture,and China’s agriculture,farmer,and countryside.

Multifractal spectrum analysis of nonlinear dynamical mechanisms in China’s agricultural futures markets

Science.gov (United States)

Chen, Shu-Peng; He, Ling-Yun

2010-04-01

Based on Partition Function and Multifractal Spectrum Analysis, we investigated the nonlinear dynamical mechanisms in China’s agricultural futures markets, namely, Dalian Commodity Exchange (DCE for short) and Zhengzhou Commodity Exchange (ZCE for short), where nearly all agricultural futures contracts are traded in the two markets. Firstly, we found nontrivial multifractal spectra, which are the empirical evidence of the existence of multifractal features, in 4 representative futures markets in China, that is, Hard Winter wheat (HW for short) and Strong Gluten wheat (SG for short) futures markets from ZCE and Soy Meal (SM for short) futures and Soy Bean No.1 (SB for short) futures markets from DCE. Secondly, by shuffling the original time series, we destroyed the underlying nonlinear temporal correlation; thus, we identified that long-range correlation mechanism constitutes major contributions in the formation in the multifractals of the markets. Thirdly, by tracking the evolution of left- and right-half spectra, we found that there exist critical points, between which there are different behaviors, in the left-half spectra for large price fluctuations; but for the right-hand spectra for small price fluctuations, the width of those increases slowly as the delay t increases in the long run. Finally, the dynamics of large fluctuations is significantly different from that of the small ones, which implies that there exist different underlying mechanisms in the formation of multifractality in the markets. Our main contributions focus on that we not only provided empirical evidence of the existence of multifractal features in China agricultural commodity futures markets; but also we pioneered in investigating the sources of the multifractality in China’s agricultural futures markets in current literature; furthermore, we investigated the nonlinear dynamical mechanisms based on spectrum analysis, which offers us insights into the underlying dynamical mechanisms in

What makes organic agriculture move: protest, meaning or market?

DEFF Research Database (Denmark)

Alrøe, Hugo; Noe, Egon

2008-01-01

Many different actors have hopes and aspirations for the future of organic agriculture. They have different perspectives on organic agriculture with different understandings of what it is and what makes it move. Each perspective entails a certain understanding of organic agriculture featuring...... certain concepts and values and a particular logic or rationality. It is important to acknowledge this heterogeneity when investigating the dynamics and governance of organic agriculture. We suggest a polyocular approach that facilitates a comprehensive and balanced understanding of organic agriculture...... by enabling us to handle different perspectives reflexively. To illustrate this approach we describe three significant perspectives on organic agriculture based on protest, meaning and market. No perspective is the 'right' one and we claim, different perspectives on organic agriculture cannot be merged to one...

1981-01-01

The market potential in the Philippines for stand alone photovoltaic (P/V) systems in agriculture was assessed. Applications include: irrigation, postharvest operation, food and fiber processing and storage, and livestock and fisheries operations. Power and energy use profiles for many applications as well as assessments of business, government and financial climate for P/V sales are described. Many characteristics of the Philippine agriculture and energy sector favorably influence the use of P/V systems. However, serious and significant barriers prevent achieving the technically feasible, cost competitive market for P/V systems in the agricultural sector. The reason for the small market is the limited availability capital for financing P/V systems. It is suggested that innovative financing schemes and promotional campaigns should be devised.

Nitrogen availability and indirect measurements of greenhouse gas emissions from aerobic and anaerobic biowaste digestates applied to agricultural soils

International Nuclear Information System (INIS)

Rigby, H.; Smith, S.R.

2013-01-01

Highlights: • Nitrogen release in digestate-amended soil depends on the digestate type. • Overall N release is modulated by digestate mineral and mineralisable N contents. • Microbial immobilisation does not influence overall release of digestate N in soil. • Digestate physical properties and soil type interact to affect overall N recovery. • High labile C inputs in digestate may promote denitrification in fine-textured soil. - Abstract: Recycling biowaste digestates on agricultural land diverts biodegradable waste from landfill disposal and represents a sustainable source of nutrients and organic matter (OM) to improve soil for crop production. However, the dynamics of nitrogen (N) release from these organic N sources must be determined to optimise their fertiliser value and management. This laboratory incubation experiment examined the effects of digestate type (aerobic and anaerobic), waste type (industrial, agricultural and municipal solid waste or sewage sludge) and soil type (sandy loam, sandy silt loam and silty clay) on N availability in digestate-amended soils and also quantified the extent and significance of the immobilisation of N within the soil microbial biomass, as a possible regulatory mechanism of N release. The digestate types examined included: dewatered, anaerobically digested biosolids (DMAD); dewatered, anaerobic mesophilic digestate from the organic fraction of municipal solid waste (DMADMSW); liquid, anaerobic co-digestate of food and animal slurry (LcoMAD) and liquid, thermophilic aerobic digestate of food waste (LTAD). Ammonium chloride (NH 4 Cl) was included as a reference treatment for mineral N. After 48 days, the final, maximum net recoveries of mineral N relative to the total N (TN) addition in the different digestates and unamended control treatments were in the decreasing order: LcoMAD, 68%; LTAD, 37%, DMAD, 20%; and DMADMSW, 11%. A transient increase in microbial biomass N (MBN) was observed with LTAD application

Environmental assessment of energy generation from agricultural and farm waste through anaerobic digestion.

While Turkey is one of the world's largest producers and exporters of agricultural goods, it is also, at the same time a net importer of energy carriers. This dichotomy offers a strong incentive to generate energy from agricultural and farming waste; something which could provide energy security for rural areas. Combined with the enhanced energy security for farming areas, the production of energy in this manner could conceivably contribute to the overall national effort to reduce the Turkey's carbon footprint. This study explores the environmental benefits and burdens of one such option, that is, biogas production from a mixture of agricultural and animal waste through anaerobic digestion (AD), and its subsequent use for electricity and heat generation. A life-cycle assessment methodology was used, to measure the potential environmental impact of this option, in terms of global warming and total weighed impact, and to contrast it with the impact of producing the same amount of energy via an integrated gasification combined cycle process and a hard coal power plant. This study concentrates on an AD and cogeneration pilot plant, built in the Kocaeli province of Turkey and attempts to evaluate its potential environmental impacts. The study uses laboratory-scale studies, as well as literature and LCI databases to derive the operational parameters, yield and emissions of the plant. The potential impacts were calculated with EDIP 2003 methodology, using GaBi 5 LCA software. The results indicate that N 2 O emissions, resulting from the application of liquid and solid portions of digestate (a by-product of AD), as an organic fertilizer, are by far the largest contributors to global warming among all the life cycle stages. They constitute 68% of the total, whereas ammonia losses from the same process are the leading cause of terrestrial eutrophication. The photochemical ozone formation potential is significantly higher for the cogeneration phase, compared to other life

A HyperSpectral Imaging (HSI) approach for bio-digestate real time monitoring

Science.gov (United States)

Bonifazi, Giuseppe; Fabbri, Andrea; Serranti, Silvia

2014-05-01

One of the key issues in developing Good Agricultural Practices (GAP) is represented by the optimal utilisation of fertilisers and herbicidal to reduce the impact of Nitrates in soils and the environment. In traditional agriculture practises, these substances were provided to the soils through the use of chemical products (inorganic/organic fertilizers, soil improvers/conditioners, etc.), usually associated to several major environmental problems, such as: water pollution and contamination, fertilizer dependency, soil acidification, trace mineral depletion, over-fertilization, high energy consumption, contribution to climate change, impacts on mycorrhizas, lack of long-term sustainability, etc. For this reason, the agricultural market is more and more interested in the utilisation of organic fertilisers and soil improvers. Among organic fertilizers, there is an emerging interest for the digestate, a sub-product resulting from anaerobic digestion (AD) processes. Several studies confirm the high properties of digestate if used as organic fertilizer and soil improver/conditioner. Digestate, in fact, is somehow similar to compost: AD converts a major part of organic nitrogen to ammonia, which is then directly available to plants as nitrogen. In this paper, new analytical tools, based on HyperSpectral Imaging (HSI) sensing devices, and related detection architectures, is presented and discussed in order to define and apply simple to use, reliable, robust and low cost strategies finalised to define and implement innovative smart detection engines for digestate characterization and monitoring. This approach is finalized to utilize this "waste product" as a valuable organic fertilizer and soil conditioner, in a reduced impact and an "ad hoc" soil fertilisation perspective. Furthermore, the possibility to contemporary utilize the HSI approach to realize a real time physicalchemical characterisation of agricultural soils (i.e. nitrogen, phosphorus, etc., detection) could

Water Market-scale Agricultural Planning: Promoting Competing Water Resource Use Efficiency Through Agro-Economics

Science.gov (United States)

Delorit, J. D.; Block, P. J.

2017-12-01

Where strong water rights law and corresponding markets exist as a coupled econo-legal mechanism, water rights holders are permitted to trade allocations to promote economic water resource use efficiency. In locations where hydrologic uncertainty drives the assignment of annual per-water right allocation values by water resource managers, collaborative water resource decision making by water rights holders, specifically those involved in agricultural production, can result in both resource and economic Pareto efficiency. Such is the case in semi-arid North Chile, where interactions between representative farmer groups, treated as competitive bilateral monopolies, and modeled at water market-scale, can provide both price and water right allocation distribution signals for unregulated, temporary water right leasing markets. For the range of feasible per-water right allocation values, a coupled agricultural-economic model is developed to describe the equilibrium distribution of water, the corresponding market price of water rights and the net surplus generated by collaboration between competing agricultural uses. Further, this research describes a per-water right inflection point for allocations where economic efficiency is not possible, and where price negotiation among competing agricultural uses is required. An investigation of the effects of water right supply and demand inequality at the market-scale is completed to characterize optimal market performance under existing water rights law. The broader insights of this research suggest that water rights holders engaged in agriculture can achieve economic benefits from forming crop-type cooperatives and by accurately assessing the economic value of allocation.

Climate Changes and Their Impact on Agricultural Market Systems: Examples from Nepal

Directory of Open Access Journals (Sweden)

Andrea Karin Barrueto

2017-11-01

Full Text Available Global climate models foresee changes in temperature and precipitation regimes that shift regional climate zones and influence the viability of agricultural market systems. Understanding the influence of climate change on the different sub-sectors and functions of a market system is crucial to increasing the systems’ climate resilience and to ensuring the long-term viability of the sectors. Our research applies a new approach to climate change analysis to better understand the influence of climate change on each step of an agricultural market system—on its core (processing units, storage facilities and sales and support functions (sapling supply, research, insurance and agricultural policy. We use spatial climate analyses to investigate current and projected changes in climate for different regions in Nepal. We then analyse the risks and vulnerabilities of the sub-sectors banana, charcoal, coffee, macadamia, orange, vegetables and walnut. Our results show that temperatures and precipitation levels will change differently depending on the climatic regions, and that climate change elicits different responses from the market functions both between and within each of the different sub-sectors. We conclude that climate-related interventions in market systems must account for each different market function’s specific response and exposure to climate change, in order to select adaptation measures that ensure long-term climate resilience.

Full Text Available This article attempts to determine the most significant tendencies and changes observed in Poland’s core markets of agricultural products, which occurred during the period preceding Poland’s accession to the European Union (1994-2003 and after the accession (2004-2013. The key markets of agricultural products include markets with the largest value of commodity production during the analysed period, such as cereals, potatoes, sugar beet, rapeseed, fruit, vegetables, pork, beef and poultry, cows’ milks and eggs. The development of domestic production, consumption and real purchasing prices were observed and compared in order to achieve the main objective. The research was preceded by the characterisation of macroeconomic and resource conditionalities of agricultural production as well as the trade balance of the Polish agri-food sector. On the basis of the conducted studies, there were singled out three groups of markets in which the situation during the period following Poland’s accession to the EU developed in a similar way.

The effects of different doses of gamma irradiation (0. 100, 150, 200 KGy) or different concentrations of urea (0, 2, 3, and 5 g urea/100 g DM) on in-vitro organic matter digestibility (JVOMD), digestible energy (IVDE), gross energy (GE) nd cell-wall constituents: neutral-detergent fibre, acid-detergent fibre and acid=detergent lignin, have been evaluated in wheat straw, cotton seed shell, peanut shell, soybean shell, extracted olive cake and extracted unpeeled sunflower seeds. The results indicated that gamma irradiation or urea treatments increased the digestible energy values significantly. (p<0.05) and these were attributed to the increases IVOMD and decreases cell-wall constituents of treated samples. The experimental agricultural by-products do not respond to the treatments in the same amount in increasing the IVOMD. There was no significant effect of irradiation and urea treatments on GE. Combined treatments had slightly less effect in increasing IVDE as the addition of both effects. The treatment of 200 KGy and 5% urea resulted in a larger increase in the digestible energy and a better effect by reducing the concentration of the cell-wall constituents even more than what occurred using a single treatment. However, the combination of irradiation with urea treatments could reduce the applied irradiation doses for increasing the IVDE in some studied agricultural by-products. (author)

2009-07-01

To evaluate the residual biogas yield during storage, biogas tests at a temperature of 22 C were performed with samples of liquid digested residue from 15 agricultural biogas plants (BGP). Values of residual biogas yield between 0.3 and 1.3 % with respect to the biogas yield from the raw input materials were measured. For the two one-stage BGP, the value was about 1.2 %. For the two-stage plants, a residual biogas yield (RBY) of 0.9 % was determined as opposed to 0.4 % for the three-stage plants. With a single exception, the RBY was clearly below 1.0 % if the overall hydraulic retention time in the BGP was equal to or larger than 100 days. For the majority of samples, the residual biogas yield showed a positive correlation with the level of volatile fatty acids in the digestate. Since the real conditions in storage tanks cannot be simulated with a simple batch-test, the results are not representative for the actual biogas production and potential methane emissions from the digestate during open storage.

Design and Fabrication of an Anaerobic Digester

Directory of Open Access Journals (Sweden)

M. S. Abubakar

2017-02-01

Full Text Available Anaerobic digester is a physical structure that provides a conducive environment for the multiplication of micro-organisms that degrades organic matter to generate biogas energy. Energy is required in agriculture for crop production, processing and storage, poultry production and electricity for farmstead and farm settlements. It is energy that propels agricultural mechanization, which minimizes the use of human and animal muscles and its inherent drudgery in agriculture. The energy demand required to meet up with the agricultural growth in Nigeria is high and growing every year. In this study the design and fabrication of an anaerobic digester was reported which is an attempt to boost energy requirement for small and medium dryland farmers in Nigeria. The design of the digester includes the following concept; the basic principles of anaerobic digestion processes, socio-economic status of the dryland farmers, amount of biogas to be produced. Finally, the digester was fabricated using locally available raw materials within the dryland area of Nigeria. At the end, preliminary flammability test was conducted and the biogas produced was found to be flammable.

The conditionings of the credit market in agriculture. The macroeconomic approach

Directory of Open Access Journals (Sweden)

Piotr Kułyk

2014-08-01

Full Text Available In this paper we have evaluated the relationship of the credit market to the agricultural sector. The weakness of appropriate resource allocation from the credit market has been emphasized. We paid attention both to the external environment of agriculture itself, as well as to the way it has been shaped as a result of the process of globalization. The effect was examined of the influence of particular macroeconomic indicators adjusted according to the range of the interest rate as a result of change in the price of agricultural products. The period of the research covered the years 1990-2010. A discussion was carried out to allow for the setting apart of factors that influenced conditions which shaped the cost of financial loans and credit. The character of dependencies or related factors were analysed. The different significance of individual accounts was shown.

A low temperature anaerobic digestion system reduces instability and produces optimal methane yield : case study of a Farrow to Finish farm marketing 10,000 hogs per year in Quebec

Villeneuve, E.; Boivin, S.; Hince, J.-F. [Bio-Terre Systems, Sherbrooke, PQ (Canada); Masse, D. [Agriculture and Agri-Food Canada, Ottawa, ON (Canada)

2008-07-01

This presentation described a joint collaboration between Agriculture and Agri-Food Canada (AAFC) and Bio-Terre Systems that resulted in the development of an innovative environmental solution for manure management. The solution which combines low-temperature anaerobic digestion, concentration of solids and production of green energy, responds to the growth of hog production in North America. A case study of a Farrow to Finish farm marketing 10,000 swine in St.-Hilaire, Quebec was presented with particular reference to background information on the farm, process stability and process performance. The Bio-Terre technology was discussed in detail including a discussion of the psychrophilic anaerobic digestion and microorganisms and sequencing batch reactor (SBR) process. The advantages and disadvantages of this process were presented. It was concluded that the process offers many benefits, including energy economy, improved health of animals, odorless spreading, better fertilizer, and reduction of land required. tabs., figs.

will be solved. Further negotiations with the ministry are necessary in order to obtain this certainty about the use of digested mixtures in agriculture. The result will probably be successful because codigestion is of interest with regard to several official policies from the government: production of sustainable energy, reduction and CO2 emissions, reduction of other greenhouse gases, reduction of mineral sur plusses in regions with intensive animal husbandry. Farm scale digestors which use the digested manure as a fertilizer on their own land have no legal difficulties. Therefore, extra attention should be given to promotion of these types of digestors. In Germany the introduction of these type of digestors is very successful and this may also be the case for the Netherlands. Large scale projects should also be promoted once the legal problems with the ministry of Agriculture has been solved. Both type of digestors should have a chance to prove themselves in the Dutch market. With the production of fertilizers for agriculture in the situation of manure surpluses it is of even more importance which price will be paid for the end product or should be paid by the producer himself in order to get rid of it. From the projects in this report surveyed it becomes clear that different prices are to be expected. The effect of these prices on the profitability of the projects is significant. Therefore more information on this subject is needed will be necessary or should be obtained. Notwithstanding the legal difficulties with agricultural application of the digested mixture, prospects of codigestion in the Netherlands has never been so favorable: attractive prices for sustainable energy and treatment of organic waste, good fiscal support for investments in sustainable energy projects and suppliers who have a wide experience in building these plants 'turn key'. Indeed difficulties exist, as have been described in this report, but the opportunities for codigestion in the

Market assessment of photovoltaic power systems for agricultural applications worldwide

Agricultural sector PV market assessments conducted in the Phillippines, Nigeria, Mexico, Morocco, and Colombia are extrapolated worldwide. The types of applications evaluated are those requiring less than 15 kW of power and operate in a stand alone mode. The major conclusions were as follows: PV will be competitive in applications requiring 2 to 3 kW of power prior to 1983; by 1986 PV system competitiveness will extend to applications requiring 4 to 6 kW of power, due to capital constraints, the private sector market may be restricted to applications requiring less than about 2 kW of power; the ultimate purchase of larger systems will be governments, either through direct purchase or loans from development banks. Though fragmented, a significant agriculture sector market for PV exists; however, the market for PV in telecommunications, signalling, rural services, and TV will be larger. Major market related factors influencing the potential for U.S. PV Sales are: lack of awareness; high first costs; shortage of long term capital; competition from German, French and Japanese companies who have government support; and low fuel prices in capital surplus countries. Strategies that may aid in overcoming some of these problems are: setting up of a trade association aimed at overcoming problems due to lack of awareness, innovative financing schemes such as lease arrangements, and designing products to match current user needs as opposed to attempting to change consumer behavior.

Methane emissions from digestate at an agricultural biogas plant.

Baldé, Hambaliou; VanderZaag, Andrew C; Burtt, Stephen D; Wagner-Riddle, Claudia; Crolla, Anna; Desjardins, Raymond L; MacDonald, Douglas J

2016-09-01

Methane (CH4) emissions were measured over two years at an earthen storage containing digestate from a mesophilic biodigester in Ontario, Canada. The digester processed dairy manure and co-substrates from the food industry, and destroyed 62% of the influent volatile solids (VS). Annual average emissions were 19gCH4m(-3)d(-1) and 0.27gCH4kg(-1)VSd(-1). About 76% of annual emissions occurred from June to October. Annual cumulative emissions from digestate corresponded to 12% of the CH4 produced within the digester. A key contributor to CH4 emissions was the sludge layer in storage, which contained as much VS as the annual discharge from the digester. These findings suggest that digestate management provides an opportunity to further enhance the benefits of biogas (i.e. reducing CH4 emissions compared to undigested liquid manure, and producing renewable energy). Potential best practices for future study include complete storage emptying, solid-liquid separation, and storage covering. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

Will EU Biofuel Policies affect Global Agricultural Markets?

International Nuclear Information System (INIS)

Banse, M.; Vvan Meijl, H.; Tabeau, A.; Woltjer, G.

2008-04-01

This paper assesses the global and sectoral implications of the European Union Biofuels Directive (BFD) in a multi-region computable general equilibrium framework with endogenous determination of land supply. The results show that, without mandatory blending policies or subsidies to stimulate the use of biofuel crops in the petroleum sector, the targets of the BFD will not be met in 2010 and 2020. With a mandatory blending policy, the enhanced demand for biofuel crops has a strong impact on agriculture at the global and European levels. The additional demand from the energy sector leads to an increase in global land use and, ultimately, a decrease in biodiversity. The development, on the other hand, might slow or reverse the long-term process of declining real agricultural prices. Moreover, assuming a further liberalization of the European agricultural market imports of biofuels are expected to increase to more than 50% of the total biofuel demand in Europe

Volatility Spillovers between Energy and Agricultural Markets: A Critical Appraisal of Theory and Practice

Directory of Open Access Journals (Sweden)

Chia-Lin Chang

2018-06-01

Full Text Available Energy and agricultural commodities and markets have been examined extensively, albeit separately, for a number of years. In the energy literature, the returns, volatility and volatility spillovers (namely, the delayed effect of a returns shock in one asset on the subsequent volatility or covolatility in another asset, among alternative energy commodities, such as oil, gasoline and ethanol across different markets, have been analysed using a variety of univariate and multivariate models, estimation techniques, data sets, and time frequencies. A similar comment applies to the separate theoretical and empirical analysis of a wide range of agricultural commodities and markets. Given the recent interest and emphasis in bio-fuels and green energy, especially bio-ethanol, which is derived from a range of agricultural products, it is not surprising that there is a topical and developing literature on the spillovers between energy and agricultural markets. Modelling and testing spillovers between the energy and agricultural markets has typically been based on estimating multivariate conditional volatility models, specifically the Baba, Engle, Kraft, and Kroner (BEKK and dynamic conditional correlation (DCC models. A serious technical deficiency is that the Quasi-Maximum Likelihood Estimates (QMLE of a Full BEKK matrix, which is typically estimated in examining volatility spillover effects, has no asymptotic properties, except by assumption, so that no valid statistical test of volatility spillovers is possible. Some papers in the literature have used the DCC model to test for volatility spillovers. However, it is well known in the financial econometrics literature that the DCC model has no regularity conditions, and that the QMLE of the parameters of DCC has no asymptotic properties, so that there is no valid statistical testing of volatility spillovers. The purpose of the paper is to evaluate the theory and practice in testing for volatility spillovers

Full Text Available After the end of the transition period for the purchase of the agricultural land by foreigners, the legislation regulating the acquisition of the agricultural land was adopted for the purpose of harmonization of the Slovak legislation with the legislation of the European Union. The Law no. 140/2014 Coll. on the acquisition of ownership to the agricultural land and amending and supplementing determines the subjects that are legitimated to acquire the ownership to the agricultural land. In addition, due to the creation of the Register of Offers of the Agricultural Land, the legislation allows the landowner to set a price on the sale of the agricultural land. In Slovakia, apart from the administrative prices and the market prices, there is a new type of prices, so-called „supply price“. The aim of the paper is to sum up the impact of the current legislation on the land market and the prices of agricultural land.

This paper investigates the role that carbon markets could have in facilitating the implementation of composting, anaerobic digestion and biochar production, in the city of Tamale, in the North of Ghana. Through a life cycle assessment of implementation scenarios for low-tech, small scale variants of the above mentioned three technologies, the potential contribution they could give to climate change mitigation was assessed. Furthermore an economic assessment was carried out to study their viability and the impact thereon of accessing carbon markets. It was found that substantial climate benefits can be achieved by avoiding landfilling of organic waste, producing electricity and substituting the use of chemical fertilizer. Biochar production could result in a net carbon sequestration. These technologies were however found not to be economically viable without external subsidies, and access to carbon markets at the considered carbon price of 7 EUR/ton of carbon would not change the situation significantly. Carbon markets could help the realization of the considered composting and anaerobic digestion systems only if the carbon price will rise above 75–84 EUR/t of carbon (respectively for anaerobic digestion and composting).

Essays on agricultural adaptation to climate change and ethanol market integration in the U.S

Science.gov (United States)

Aisabokhae, Ruth Ada

Climate factors like precipitation and temperature, being closely intertwined with agriculture, make a changing climate a big concern for the entire human race and its basic survival. Adaptation to climate is a long-running characteristic of agriculture evidenced by the varying types and forms of agricultural enterprises associated with differing climatic conditions. Nevertheless climate change poses a substantial, additional adaptation challenge for agriculture. Mitigation encompasses efforts to reduce the current and future extent of climate change. Biofuels production, for instance, expands agriculture's role in climate change mitigation. This dissertation encompasses adaptation and mitigation strategies as a response to climate change in the U.S. by examining comprehensively scientific findings on agricultural adaptation to climate change; developing information on the costs and benefits of select adaptations to examine what adaptations are most desirable, for which society can further devote its resources; and studying how ethanol prices are interrelated across, and transmitted within the U.S., and the markets that play an important role in these dynamics. Quantitative analysis using the Forestry and Agricultural Sector Optimization Model (FASOM) shows adaptation to be highly beneficial to agriculture. On-farm varietal and other adaptations contributions outweigh a mix shift northwards significantly, implying progressive technical change and significant returns to adaptation research and investment focused on farm management and varietal adaptations could be quite beneficial over time. Northward shift of corn-acre weighted centroids observed indicates that substantial production potential may shift across regions with the possibility of less production in the South, and more in the North, and thereby, potential redistribution of income. Time series techniques employed to study ethanol price dynamics show that the markets studied are co-integrated and strongly

Customer relationship management in the agricultural machinery market

Directory of Open Access Journals (Sweden)

Amanda Letícia Pit Nunes

Full Text Available ABSTRACT: Customer Relationship Management can be regarded as a business approach. The objective was to know the customers, meet their expectations, and thus build customer loyalty. Although, the agricultural sector makes significant economic contributions to the Brazilian market and induces sharp competition among its companies, a huge opportunity still presents itself for the diffusion and implementation of CRM in the agricultural machinery sector. This study aimed to highlight the importance of customer management, by introducing the customer relationship management (CRM concept. This is possible in the event of reselling agricultural machines, with the intention of retaining the customers and raising the profitability of these companies. It is necessary to understand CRM as more than a mere a concept or a tool. It is a business strategy, an endeavor that must be endorsed by the entire company. The concessionaire must be perceived as greater than a mere reseller. It is to be viewed rather as a problem solver, as one who offers services that are high in quality and meet client specifics.

Agricultural and Social Resiliency of Small-Scale Agriculture to Economic and Climatic Shocks: A Comparison of Subsistence versus Market-Based Agricultural Approaches in Rural Guatemala

Science.gov (United States)

Malard, J. J.; Melgar-Quiñonez, H.; Pineda, P.; Gálvez, J.; Adamowski, J. F.

2014-12-01

Agricultural production is heavily dependent not only on climate but also on markets as well as on the social and community systems managing the agroecosystem. In addition, the ultimate goal of agricultural production, human food security, is also affected not only by net agricultural production but also by similar economic and social factors. These complex feedbacks assume a particular importance in the case of smallholder farms in the tropics, where alternative rural development policies have led to different and contrasting agricultural management systems. Current approaches at comparing such systems generally study their environmental, economic or social components in isolation, potentially missing important interconnections. This research uses a participatory systems dynamics modelling (SDM) framework to compare two small-scale agricultural approaches in rural Guatemala which differ in their social, economic and ecosystem management decisions. The first case study community, in Quiché, has adopted a subsistence-based system that aims to use low levels of outside inputs to produce food for their own consumption, while the second, in Sololá, has opted for market-based agriculture that uses high input levels to obtain marketable crops in order to assure income for the purchase of food and other necessities. Each of these systems has its respective vulnerabilities; while the Sololá community suffers from more environmental degradation issues (soils and pests), the Quiché community, given lower monetary incomes, is more vulnerable to events whose responses require a significant monetary expenditure. Through the SDM approach, we incorporate local stakeholder knowledge of the respective systems, including biophysical and socioeconomic variables, into a joint biophysical and socioeconomic model for each community. These models then allow for the comparison of the resilience of both types of socio-agroecosystems in the face of climatic, economic and biological

To assess whether state-sponsored agricultural marketing programs had a positive influence on adult consumers' fruit and vegetable consumption. Differences in fruit and vegetable consumption between 2000 and 2005 in states that initiated marketing campaigns during this period and those that did not were examined. A representative sample (n  =  237,320) of adults aged 18 and older from states with and without marketing programs was used. The study used data from the 2000 and 2005 Behavioral Risk Factor Surveillance System. The number of fruit and vegetable servings per week and the percentage of respondents consuming five or more servings of fruits and vegetables per day were examined. Between-subjects analysis of variance and logistic regression. In the absence of a marketing campaign, there was a significant decrease in fruit and vegetable consumption between 2000 and 2005. In states with campaigns, consumption remained stable or increased. Marketing effects were stronger for women than for men. Conclusions . State-sponsored agricultural marketing programs had favorable effects on consumers' consumption of fruits and vegetables.

2017-11-01

Full Text Available One of the main problems of the world in the coming years is food security. The main problem of agriculture in the future is not only to produce more, but to do so in a sustainable way. European Innovation Partnership called "Productivity and sustainability of agriculture" aims to provide a working interface between agriculture, bio-economy, science and other disciplines at national, regional and EU level. European Innovation Partnership is a new concept that was introduced in Strategy Europe 2020 of the European Commission. In this document, the Commission underlines the role of research and innovation as key elements in adapting to future challenges of the European Union. This partnership will also serve as a catalyst to increase the effectiveness of actions related to innovation supported through rural development policy, EU research and innovation. It has been identified two main objectives for the European Innovation Partnership: promoting productivity and efficiency of agriculture and durable agriculture sustainability in all Member States. It aims to create a better cooperation between research and agricultural practice, namely farmers. Through National Program for Rural Development 2014 - 2020, can be financed such initiatives, through Measure 16, sub-16.1 - Support for the establishment and operation of operational groups of the EIP for agricultural productivity and sustainability and sub-16.2 - Support for pilot projects and development of new products, practices, processes and technologies. The purpose of these sub-measures is to support the establishment of operational groups between partners coming from research: research institutes, research stations or centers, higher education institutions that have research in agriculture or which can be applied in agriculture and agricultural producers (farmers, companies, cooperatives and producer groups. Development and innovation activities would enable farmers to capitalize on joint the

Duopoly price competition on markets with agricultural products

Directory of Open Access Journals (Sweden)

Marie Prášilová

2011-01-01

Full Text Available A situation, in which two firms compete, is in the economic theory described by duopoly models. Market equilibrium on the duopoly market is formed in a reciprocal adjustment process of market prices and materialized market opportunities. The goal of the analysis is to find out whether the agricultural products market is significantly influenced by appearance of duopolies, what form they have and if they can fundamentally influence the price level of food. That food chain stores endeavour to mutually adapt food product prices is generally known; it is set especially by the inelastic demand for the mentioned goods on the side of consumers, i.e., by the need to demand basic food. Duopoly reactions to price competition in food chain stores are particularly strong in the case of commodities of milk and tomatoes, where the reactions and approximation of prices can be clearly seen. Based on statistical research it is obvious that the reactions are most reflected on sales of the food chain stores Billa and Albert. To identify specific reactions of price duopoly at retail chains the ANOVA statistical method was used. The firm’s duopoly behaviour as such on the food market need not be a subject for applying punishment from the antimonopoly bureau, if it does not have the cartel agreement character. An example can be the identical potato prices inquiry in the supermarkets of food chain stores.

Agriculture in the intermountain western United States is dominated by extensive farming and ranching, mostly reliant on rainfed crops and therefore very exposed to precipitation shortfalls. It is also poorly diversified, dominated by five or six major grain crops, which makes it vulnerable to changes in agricultural markets. The economy of the region is very reliant on this type of agriculture, making the entire economy vulnerable to climatic and market fluctuations. Western agriculture is also of significant importance for national food security. Resource managers in the region are increasingly concerned with the impacts that more frequent and severe droughts, or the collapse of crop prices, may have on producers and food production. Effective resource management requires an understanding not only of the regional impact of adverse climatic and market events, but also of which geographic areas are most vulnerable, and why. Unfortunately, few studies exist that look into how farmers in different geographic areas respond to climate and market drivers. In this study we analyze the influence of precipitation and crop price anomalies on crop production, and map the characteristic time scale of these anomalies that correlate best with production anomalies for the 56 counties of Montana, U.S.A. We conduct this analysis using the standardized precipitation index (SPI), and defining a standardized crop value index (SCVI) and a standardized crop production index (SCPI). We use 38 years of data to calculate precipitation anomalies at monthly time scales and annual data to calculate crop price and production anomalies. The standardization of the indices allows for straightforward comparison of the relative influence of climatic and market fluctuations on production anomalies. We apply our methodology to winter wheat, spring durum wheat, barley, alfalfa, and beets which are the most valuable crops produced in the state. Results from this study show that precipitation anomalies

Full Text Available Planning and distribution economy with state ownership of agricultural enterprises, which were dominant in the early 90s the economy of the country, was unable to provide normal functioning of the agricultural land use in the conditions of transition to market relations. To switch to another economic system began a gradual process of transformation of agricultural enterprises. The result of this process was the change in the structure of agrarian enterprises due to privatization and raspaevaniya land, and appearance from small-scale farms to large agricultural enterprises. Today identified market actors (enterprises in agriculture: business companies, private enterprises, production cooperatives, farmers, public enterprises, other forms of management. The most common kind of private business are farms. They are one of the most promising and effective forms of management with high agriculture, appropriate level of production organization, prudent attitude to the land and best landscaping. However, today the formation of farming in Ukraine has not yet reached the level of development, which is observed in economically developed countries. The overall economic decline and inadequate legislation has forced farmers to rely on themselves. Notes the insufficient level of their competitiveness, making it impossible to provide the expanded reproduction, determines the risk of insolvency and, as a consequence, leads to bankruptcy. Farmers receive government support, but it is weak and temporary, which greatly impedes their development. Practical state support only a few farms that can affect the distribution of funds. Agricultural cooperation is one of the effective forms of management, which aims to unite the producers in the direction of increase of efficiency of use of their resource potential. However, today there are a number of unresolved problems that hinder the effective development of agricultural cooperatives. Since 2000 years, the initiative in

Substrate-induced instability of anaerobic digestion from fruit and vegetable waste (FVW) results in low biogas yield. In this study, substrate management through fruit to vegetable mix ratio in a two-stage semi-continuous digester was investigated as a pathway for optimality of yield. The experiment conducted over 105 days with 62.52 kg of FVWs sourced from Joburg Market, South Africa showed that a stable process was achieved at a fruit to vegetable waste mix ratio of 2.2:2.8. At this ratio, optimal organic loading rate ranged between 2.68 and 2.97 kg VS/m 3 -d which resulted in a specific biogas yield of 0.87 Nm 3 /kg VS with 57.58% methane on average. The results of the experimental study were used as a feasibility assessment for a full-scale 45 tonnes/d plant for Joburg Market considering three energy pathways. The plant will produce 1,605,455 Nm 3 /y of biogas with the potential for offsetting 15.2% of the Joburg Market energy demand. Conversion of all biogas to biomethane was the most economically attractive energy pathway with a net present value of $2,428,021, an internal rate of return of 16.90% and a simple payback period of 6.17 years. This route avoided the greenhouse gas emission of 12,393 tonnes CO 2 , eq. The study shows that the anaerobic digestion of FVWs as sole substrate is possible with financial and environmental attractiveness. Copyright © 2018 Elsevier Ltd. All rights reserved.

Cross-correlations between agricultural commodity futures markets in the US and China

2012-08-01

This paper examines the cross-correlation properties of agricultural futures markets between the US and China using a cross-correlation statistic test and multifractal detrended cross-correlation analysis (MF-DCCA). The results show that the cross-correlations between the two geographically distant markets for four pairs of important agricultural commodities futures are significantly multifractal. By introducing the concept of a “crossover”, we find that the multifractality of cross-correlations between the two markets is not long lasting. The cross-correlations in the short term are more strongly multifractal, but they are weakly so in the long term. Moreover, cross-correlations of small fluctuations are persistent and those of large fluctuations are anti-persistent in the short term while cross-correlations of all kinds of fluctuations for soy bean and soy meal futures are persistent and for corn and wheat futures are anti-persistent in the long term. We also find that cross-correlation exponents are less than the averaged generalized Hurst exponent when q0 in the short term, while in the long term they are almost the same.

Full Text Available Green agriculture can improve biodiversity, increase farmers’ income, reduce agricultural non-point source pollution, solve food safety issues, and will be an important way to promote sustainable development in China. At present, the green transformation of China’s agriculture has encountered a bottleneck in the development of a green agricultural product market. How to develop a green agricultural product market has become an issue worthy of in-depth study in the academia. Previous studies have already given persuasive explanations for the inability to form a green agricultural product market, but few have explored its development path from the angle of cooperation. By employing the method of a Transferable Utilities (TU cooperative game, and based on theoretical analyses and hypothetical data, this thesis aims to prove the effectiveness of the multilateral coalition to develop the green agricultural product market in China. The results show the effectiveness of the developed model of the green agricultural product market in which producers, consumers, food safety inspection departments, and e-commerce platforms cooperate with each other. This model meets the objective needs of the times and that of the market economy. According to the marginal contribution value of participants in different coalition orders, this thesis finds 6 kinds of coalition orders. When producers and consumers of green agricultural products enter the coalition in the last place, the marginal contribution value is maximized, which reflects the importance of the supply side and demand side of green agricultural products. In other words, the development of the green agricultural product market is a dynamic process—determined by consumers and promoted by producers—in which both sides promote and restrict each other. Finally, this article presents two policy recommendations: at the national level, to clearly proposes a strategy to build a green agricultural product e

What role will climate change play in EU agricultural markets? An integrated assessment taking into account carbon fertilization effects

Energy Technology Data Exchange (ETDEWEB)

Martinez, P.; Blanco, M.; Van Doorslaer, B.; Ramos, F.; Ceglar, A.

2017-07-01

Recent studies point to climate change being one of the long-term drivers of agricultural market uncertainty. To advance in the understanding of the influence of climate change on future agricultural market developments, we compared a baseline scenario for the year 2030 with alternative simulation scenarios that differ regarding: (1) emission scenarios; (2) climate projections; and (3) the consideration of carbon fertilization effects on crop growth. For each simulation scenario, the CAPRI model provides global and EU-wide impacts of climate change on agricultural markets. Results showed that climate change would considerably affect agrifood markets up to 2030. Nevertheless, market-driven adaptation strategies (production intensification, trade adjustments) would soften the impact of yield shocks on supply and demand. As a result, regional changes in production would be lower than foreseen by other studies focused on supply effects.

Full Text Available The successful development of Northern and Arctic areas depends on sustainable functioning of the agricultural sector. Agriculture and fishing agriculture is a way of life of the indigenous population. The article discusses the state of agriculture and food self-sufficiency in the Komi Republic in the years of relatively stable development (1960–1980 and in the conditions of market reforms. It analyzes production and consumption of food and shows a positive effect of modernization processes on the agricultural sector in the pre-reform period. It studies market transformation of the agrarian economy, accompanied in the 1990s by the sharp decline in agricultural production, degradation of productive capacity, rural demography, rural infrastructure, decrease in living standard of farmers, and disparity of prices on agricultural and industrial products. The paper discloses trends in food self-sufficiency of the northern region in 1980–2013 and reveals reasons for the decrease in its level in the period of market reforms. It considers possible scenarios to develop the agrarian sector and food self-sufficiency. To predict the agriculture development the author identifies strong and weak sides, opportunities and threats by means of SWOT-analysis. The article proposes 3 scenarios: inertial (pessimistic, baseline and optimistic. It finds out the most reasonable optimistic development scenario based on innovative modernization for the Komi Republic. The study results can be used to adjust the current State program of agricultural development and elaborate the strategy of the agro-food sector of the region

A study of the cost-effective markets for new technology agricultural aircraft

Hazelrigg, G. A., Jr.; Clyne, F.

1979-01-01

A previously developed data base was used to estimate the regional and total U.S. cost-effective markets for a new technology agricultural aircraft as incorporating features which could result from NASA-sponsored aerial applications research. The results show that the long-term market penetration of a new technology aircraft would be near 3,000 aircraft. This market penetration would be attained in approximately 20 years. Annual sales would be about 200 aircraft after 5 to 6 years of introduction. The net present value of cost savings benefit which this aircraft would yield (measured on an infinite horizon basis) would be about $35 million counted at a 10 percent discount rate and $120 million at a 5 percent discount rate. At both discount rates the present value of cost savings exceeds the present value of research and development (R&D) costs estimated for the development of the technology base needed for the proposed aircraft. These results are quite conservative as they have been derived neglecting future growth in the agricultural aviation industry, which has been averaging about 12 percent per year over the past several years.

The impact of German biogas production on European and global agricultural markets, land use and the environment

International Nuclear Information System (INIS)

Britz, Wolfgang; Delzeit, Ruth

2013-01-01

As part of its climate policy, Germany promotes the production of biogas via its so-called Renewable-Energy-Act (EEG). The resulting boost in biogas output went along with a significant increase in production of green maize, the dominant feedstock. Existing studies of the EEG have analysed its impacts on German agriculture without considering market feedback. We thus expand existing quantitative analysis by also considering impacts on European and global agricultural markets, land use and the environment by combining a detailed location model for biogas plants, the Regionalised Location Information System-Maize (ReSi-M2012), with a global Partial Equilibrium model for agriculture, the Common Agricultural Policy Regional Impact (CAPRI) model. Our results indicate that the German biogas production is large enough to have sizeable impacts on global agricultural markets in prices and quantities, causing significant land use change outside of Germany. While profits in the agricultural sector increase, food consumer face higher prices, and subsidies for biogas production are passed on to electricity consumers. The German biogas program, as long as it is almost entirely based on non-waste feedstocks, is probably not a promising avenue towards a GHG-saving renewable energy production, but a rather expensive one. - Highlights: • Recent changes to that program decrease green maize use but increase land demands. • The program could raise EU prices for cereals by 3%. • Agricultural land use expansion outside of the EU estimated at 1 Mio ha

Comparison of digestion methods to determine heavy metals in fertilizers

Full Text Available The lack of a standard method to regulate heavy metal determination in Brazilian fertilizers and the subsequent use of several digestion methods have produced variations in the results, hampering interpretation. Thus, the aim of this study was to compare the effectiveness of three digestion methods for determination of metals such as Cd, Ni, Pb, and Cr in fertilizers. Samples of 45 fertilizers marketed in northeastern Brazil were used. A fertilizer sample with heavy metal contents certified by the US National Institute of Standards and Technology (NIST was used as control. The following fertilizers were tested: rock phosphate; organo-mineral fertilizer with rock phosphate; single superphosphate; triple superphosphate; mixed N-P-K fertilizer; and fertilizer with micronutrients. The substances were digested according to the method recommended by the Ministry for Agriculture, Livestock and Supply of Brazil (MAPA and by the two methods 3051A and 3052 of the United States Environmental Protection Agency (USEPA. By the USEPA method 3052, higher portions of the less soluble metals such as Ni and Pb were recovered, indicating that the conventional digestion methods for fertilizers underestimate the total amount of these elements. The results of the USEPA method 3051A were very similar to those of the method currently used in Brazil (Brasil, 2006. The latter is preferable, in view of the lower cost requirement for acids, a shorter digestion period and greater reproducibility.

Model-based design of an agricultural biogas plant: application of anaerobic digestion model no.1 for an improved four chamber scheme.

Wett, B; Schoen, M; Phothilangka, P; Wackerle, F; Insam, H

2007-01-01

Different digestion technologies for various substrates are addressed by the generic process description of Anaerobic Digestion Model No. 1. In the case of manure or agricultural wastes a priori knowledge about the substrate in terms of ADM1 compounds is lacking and influent characterisation becomes a major issue. The actual project has been initiated for promotion of biogas technology in agriculture and for expansion of profitability also to rather small capacity systems. In order to avoid costly individual planning and installation of each facility a standardised design approach needs to be elaborated. This intention pleads for bio kinetic modelling as a systematic tool for process design and optimisation. Cofermentation under field conditions was observed, quality data and flow data were recorded and mass flow balances were calculated. In the laboratory different substrates have been digested separately in parallel under specified conditions. A configuration of four ADM1 model reactors was set up. Model calibration identified disintegration rate, decay rates for sugar degraders and half saturation constant for sugar as the three most sensitive parameters showing values (except the latter) about one order of magnitude higher than default parameters. Finally, the model is applied to the comparison of different reactor configurations and volume partitions. Another optimisation objective is robustness and load flexibility, i.e. the same configuration should be adaptive to different load situations only by a simple recycle control in order to establish a standardised design.

Full Text Available Almost all countries in the world actively regulate both import and export of agricultural products, however this process is very conflictгфд because of acute contradictions on the market. They are associated with the changing conditions of production, increase of attention of the world community to the food securitysituation, change of the used resources efficiency level, competition enhancement. Both internal and external components of agricultural producers support are important for Russia. That means the regulation should be aimed at meeting the needs of the domestic market and at increasing competitiveness of Russian products abroad. The development of the Russian export strategy for agricultural products is currently very important. This problem is closely related to the general subject of the agricultural productiondevelopment, but it has an explicit specific character. Inthiscontextexperienceofforeigncountriesisinteresting. Almost all tools of export regulation existing in the world practice are used in the foreign practice of export regulation of agricultural raw materials and food. Stimulation measures prevail in regards to the coverage of commodity items, number of episodes involving the use of agricultural export regulationmeasures, effectiveness of impact to the national agricultural sector. Holistic strategies of agricultural export development are not a widespread phenomenon abroad at the present stage of the world economy development. Their existence is typical for countries with a high level of food self-sufficiency. Special programs where export component is a harmonically built-in element are now more widely spread. Export development programs of the developed countries include a range of measures to maintain the target income level of producers and to maintain procurement and consumer prices. Export policy of the developing countries has a subordinated importance and is considered as one of the levels to develop national

Evaluating the impacts of farmers' behaviors on a hypothetical agricultural water market based on double auction

Agricultural water markets are considered effective instruments to mitigate the impacts of water scarcity and to increase crop production. However, previous studies have limited understanding of how farmers' behaviors affect the performance of water markets. This study develops an agent-based model to explicitly incorporate farmers' behaviors, namely irrigation behavior (represented by farmers' sensitivity to soil water deficit λ) and bidding behavior (represented by farmers' rent seeking μ and learning rate β), in a hypothetical water market based on a double auction. The model is applied to the Guadalupe River Basin in Texas to simulate a hypothetical agricultural water market under various hydrological conditions. It is found that the joint impacts of the behavioral parameters on the water market are strong and complex. In particular, among the three behavioral parameters, λ affects the water market potential and its impacts on the performance of the water market are significant under most scenarios. The impacts of μ or β on the performance of the water market depend on the other two parameters. The water market could significantly increase crop production only when the following conditions are satisfied: (1) λ is small and (2) μ is small and/or β is large. The first condition requires efficient irrigation scheduling, and the second requires well-developed water market institutions that provide incentives to bid true valuation of water permits.

Radiocesium and radiostrontium are among the most problematic soil contaminants following nuclear fallout due to their long half-lives and high fission yields. Their chemical resemblance to potassium, ammonium and calcium facilitates their plant uptake and thus enhances their chance to reach humans through the food-chain dramatically. The plant uptake of both radionuclides is affected by the type of soil, the amount of organic matter and the concentration of competitive ions. In the present lysimeter scale experiment, soil-plant transfer of Cs-137 and Sr-90 was investigated in an agricultural silty soil amended with digestate, a residue from a biogas plant. The liquid fraction of the digestate, liquor, was used to have higher nutrient competition. Digestate application was done in accordance with the field practice with an application rate of 34 Mg/ha and mixing it in top 5 cm soil, yielding a final concentration of 38 g digestate/Kg soil. The top 5 cm soil of the non-amended reference soil was also submitted to the same mixing procedure to account for the physical disturbance of the top soil layer. Six months after the amendment of the soil, the soil contamination was done with water-soluble chloride salts of both radionuclides, resulting in a contamination density of 66 MBq/m2 for Cs-137 and 18 MBq/m2 for Sr-90 in separate experiments. Our results show that digestate application led to a detectable difference in soil-plant transfer of the investigated radionuclides, effect was more pronounced for Cs-137. A clear difference was observed in plant uptake of different plants. Pest plants displayed higher uptake of both radionuclides compared to wheat. Furthermore, lower activity values were recorded in ears compared to stems for both radionuclides.

Full Text Available The goal of the article lies in development and approval of the indicator of complex assessment of the level of price and structure risks of agricultural enterprises with the further goal of selecting a marketing strategy. It was established in the result of the study that agricultural enterprises with a high price and structure risk ratio have high indicators of economic efficiency compared to the groups with a low value of this indicator. At the same time, major enterprises (mostly agro-holdings at a certain stage, which corresponds with the set critical size of the area or livestock, have a possibility to diversify production and, consequently, reduce the price and structure risk ratio. Further studies would deal with establishing groups of agricultural enterprises on the basis of differences in economic efficiency by selected criteria (profitability of realisation of products, profit per 1 hectare and crop capacity and livestock productivity, that result not from the territorial and geographical location, but from specific features of formation of the market of agrarian products of Ukraine.

Market assessment of photovoltaic power systems for agricultural applications in Morocco

Steingass, H.; Asmon, I.

1981-01-01

Results of a month-long study in Morocco aimed at assessing the market potential for stand-alone photovoltaic systems in agriculture and rural service applications are presented. The following applications, requiring less than 15 kW of power, are described: irrigation, cattle watering, refrigeration, crop processing, potable water and educational TV. Telecommunications and transportation signalling applications, descriptions of power and energy use profiles, assessments of business environment, government and private sector attitudes towards photovoltaics, and financing were also considered. The Moroccan market presents both advantages and disadvantages for American PV manufacturers. The principle advantages of the Moroccan market are: a limited grid, interest in and present use of PV in communications applications, attractive investment incentives, and a stated policy favoring American investment. Disadvantages include: lack of government incentives for PV use, general unfamiliarity with PV technology, high first cost of PV, a well-established market network for diesel generators, and difficulty with financing. The market for PV in Morocco (1981-1986), will be relatively small, about 340 kwp. The market for PV is likely to be more favorable in telecommunications, transport signalling and some rural services. The primary market appears to be in the public (i.e., government) rather than private sector, due to financial constraints and the high price of PV relative to conventional power sector.

Agricultural support is a very important element in agricultural policy in many countries. Agricultural support is basically an instrument to meet the overall objectives of the agricultural policy – objectives set by society. There are a great number of instruments and ways of intervention...... in agricultural policy and they have different functions and impacts. Market price support and deficiency payments are two very important instruments in agricultural policy; however, they belong to two different support regimes or support systems. Market price support operates in the so-called high price system...

Charlebois, Pierre; Hamann, Nathalie

2010-01-01

World prices for basic food commodities increased significantly in 2007-2008, triggering a worldwide food crisis. Among all the factors that contributed to the rise in agricultural prices in 2008, the depreciation of the U.S. dollar relative to other major currencies cannot be overlooked. The currencies of the major players in agricultural markets have shown strong appreciation from 2002 to 2008. The purpose of this study is to determine the effect of a strong depreciation of the U.S. dollar ...

Agricultural marketing in a country in transition : case of sweetpotato products in Sichuan, P.R. China

Zhang, X.

1999-01-01

China's achievements in its reform from a centrally planned economy toward a marketing economy during the last two decades are substantial. Although it still has a long way to go to reach its targeted aims, half of China's economy is now 'marketised, or is responsive to market forces (Lawrence, 1998). The influence of the transition on agricultural marketing is significant, particularly when the reforms were initiated by farmers and started in rural areas. The sweetpotato sector, one...

Agricultural and oil commodities: price transmission and market integration between US and Italy

Directory of Open Access Journals (Sweden)

Franco Rosa

2014-08-01

Full Text Available Purpose of this article it to get some evidences of market interaction between United States and Italy using the time series analysis of spot prices spanning from January 1999 to May 2012 for crude oil and three ag-commodities: wheat, corn and soybean. These crops have been selected for their relevance in ag-commodity exchanges between US and Italy markets. The integration between US and Italy agricultural markets is hypothesized for the consistent volume of crop traded between these two countries while the price transmission is related to the leading price signals of the CBT (Chicago Board of Trade. The integration between oil and ag-commodity markets is suggested both by the large use of energy intensive inputs, (fertilizer, seed, machinery in production of these ag-commodities, and their use in biofuel production. The results suggest: a for US market the evidence of market integration between crude oil and US ag-commodities; b for Italy the integration with US ag-commodity markets and less evidence of integration with the oil market. These results are valuable information both for the agents and policy makers contributing to improve the information accuracy to predict the price movements used by marketing operators for their strategies and policy makers to set up policies to re-establish conditions of market efficiency and allocate these ag-commodities in alternative market channels.

The sustainability of an agricultural system depends highly upon the recycling of all useful substances from agricultural wastes. This study explored the feasibility of comprehensive utilization of C, N and P resources in swine manure (SM) through short-term dry anaerobic digestion (AD) followed by dry ammonia stripping, aiming at achieving (1) effective total volatile fatty acids (VFAs) production and separation; (2) ammonia recovery from the digestate; and (3) preservation of high P bioavailability in the solid residue for further applications. Specifically, two ammonia stripping strategies were applied and compared in this work: (I) ammonia stripping was directly performed with the digestate from dry AD of SM (i.e. dry ammonia stripping); and (II) wet ammonia stripping was conducted by using the resultant filtrate from solid-liquid separation of the mixture of digestate and added water. Results showed that dry AD of the tested SM at 55 °C, 20% TS and unadjusted initial pH (8.6) for 8 days produced relatively high concentrations of total VFAs (94.4 mg-COD/g-VS) and ammonia-N (20.0 mg/g-VS) with high potentially bioavailable P (10.6 mg/g-TS) remained in the digestate, which was considered optimal in this study. In addition, high ammonia removal efficiencies of 96.2% and 99.7% were achieved through 3 h' dry and wet stripping (at 55 °C and initial pH 11.0), respectively, while the total VFAs concentration in the digestate/filtrate remained favorably unchanged. All experimental data from the two stripping processes well fitted to the pseudo first-order kinetic model (R(2) = 0.9916-0.9997) with comparable theoretical maximum ammonia removal efficiencies (Aeq, >90%) being obtained under the tested dry and wet stripping conditions, implying that the former was more advantageous due to its much higher volumetric total ammonia-N removal rate thus much smaller reactor volume, less energy/chemicals consumption and no foaming problems. After 8 days' dry AD and 3�

Improving biogas quality and methane yield via co-digestion of agricultural and urban biomass wastes.

Science.gov (United States)

Poulsen, Tjalfe G; Adelard, Laetitia

2016-08-01

Impact of co-digestion versus mono-digestion on biogas and CH4 yield for a set of five biomass materials (vegetable food waste, cow dung, pig manure, grass clippings, and chicken manure) was investigated considering 95 different biomass mixes of the five materials under thermophilic conditions in bench-scale batch experiments over a period of 65days. Average biogas and CH4 yields were significantly higher during co-digestion than during mono-digestion of the same materials. This improvement was most significant for co-digestion experiments involving three biomass types, although it was independent of the specific biomasses being co-digested. Improvement in CH4 production was further more prominent early in the digestion process during co-digestion compared to mono-digestion. Co-digestion also appeared to increase the ultimate CH4/CO2 ratio of the gas produced compared to mono-digestion although this tendency was relatively weak and not statistically significant.

Voluntary Certification of Agricultural Products in Competitive Markets: The Consideration of Boundedly Rational Consumers

Directory of Open Access Journals (Sweden)

Xujin Pu

2016-09-01

Full Text Available Market competition creates strategic incentives for firms to communicate private information about their own product quality through certification. Although voluntary certification has recently gained importance in the agricultural industry, information asymmetry is not always completely addressed. This study analyzes how the relative proportion of boundedly rational consumers in the market influences the effectiveness of voluntary certification mechanisms by using a duopoly game model of high- and low-quality firms. The presented results show that a change in the proportion of boundedly rational consumers leads to different certification behaviors and a different market equilibrium. We also find that the existence of boundedly rational consumers is an important factor in the failure of voluntary certification. Indeed, when the relative proportion of such consumers is very high, voluntary certification is ineffective at improving market efficiency.

Using social marketing to address barriers and motivators to agricultural safety and health best practices.

Science.gov (United States)

Yoder, Aaron M; Murphy, Dennis J

2012-01-01

Social marketing is an intervention development strategy that pays considerable attention to barriers to and motivators for behavioral change or adoption of recommended behaviors. Barriers are obstacles that prevent individuals from changing or adopting behaviors and are often referred to as the "cons" or "costs" of doing something. Motivators, on the other hand, are factors that encourage individuals to change or adopt behaviors and are often referred to as the "pros," "benefits," or "influencing factors" of doing something. Importantly, social marketing does not target education or knowledge change as an end point; rather, it targets behavior change. Studies across several types of desired behaviors (e.g., smoking cessation, weight control, more exercise, sunscreen use, radon testing) using the Stages of Change model have found systematic relationships between stages of change and pros and cons of changing behavior. A review of literature identifies numerous research and intervention studies that directly reference social marketing in agricultural safety and health, studies that identify reasons why parents allow their children to be exposed to hazardous situations on the farm, and reasons why youth engage in risky behaviors, but only two studies were found that show evidence of systematically researching specific behavioral change motivating factors. The authors offer several suggestions to help address issues relating to social marketing and agricultural safety and health.

The role of the agricultural credit cooperatives in the fertilizer market in Turkey

International Nuclear Information System (INIS)

Akcay, Y.; Cicek, A.; Akay, M.; Sayili, M.; Uzunoez, M.

1999-01-01

Agriculture has a certain degree of importance in the development and developing countries in the world. It is necessary to increase agricultural production and productivity to counter balance increasing food demand. To be able to reach to the goal, inputs one of which is fertilizer used in the agricultural production should be used in the optimum amount in the modern agriculture. Increasing the productivity in the agricultural production depends on the transformation of economic unity of the farms (Karacan, 1991). However, approximately 85 percentage of the farmers in Turkey has made agricultural activity on the farm land which is smaller than that of 100 decar (1 decar = 1000 m 2 ). This case has shown that there is a domination of the type of small family farms in Turkish agriculture. These farms generally have insufficient capital, saving, modern equipment, input usage and credit. This farm structure has increased the importance of the agricultural credit cooperatives (ACC) providing credit either inputs or cash. And also ACC have played an important role to transfer finance from government to farmers (Muelayim, 1995). The first main goal of the study is to determine the role of the ACC having a great importance in the fertilizer market in Turkey. The second goal is to evaluate the relationship between farmers-ACC and farmers-private fertilizer agent in the selected region, central district of Tokat province. Also the problems that the farmers faced and the preference of buying fertilizer from either ACC or private fertilizer agent of the farmers and some suggestions related to the subjects were investigated.

Potential of anaerobic digestion for mitigation of greenhouse gas emissions and production of renewable energy from agriculture: barriers and incentives to widespread adoption in Europe.

Science.gov (United States)

Banks, C J; Salter, A M; Chesshire, M

2007-01-01

The paper considers the role of anaerobic digestion in promoting good agricultural practice on farms and the contribution this would make to reducing the environmental impacts associated with manure management. There are no regulatory drivers to promote the use of digestion in Europe, and the technology has only been widely adopted where economic drivers and coherent policies have been implemented at a national level. These measures have included direct subsidy on the energy price paid for "green electricity", and exemption of tax when biogas is used as a vehicle fuel. In those countries where financial incentives are not available or where a financial penalty is incurred through the regulatory regime, the uptake of digestion has been poor. Even with subsidies, digestion of animal manures as a single substrate is not common, and countries with successful schemes have achieved this either by permitting the import of wastes onto the farm or offering bonus subsidies for the use of energy crops. Both of these measures improve the energy efficiency of the process by increasing the volumetric methane production, although concerns are expressed that attention could concentrate on energy production at the expense of improving manure management.

Factors controlling pathogen destruction during anaerobic digestion of biowastes

International Nuclear Information System (INIS)

Smith, S.R.; Lang, N.L.; Cheung, K.H.M.; Spanoudaki, K.

2005-01-01

Anaerobic digestion is the principal method of stabilising biosolids from urban wastewater treatment in the UK, and it also has application for the treatment of other types of biowaste. Increasing awareness of the potential risks to human and animal health from environmental sources of pathogens has focused attention on the efficacy of waste treatment processes at destroying pathogenic microorganisms in biowastes recycled to agricultural land. The degree of disinfection achieved by a particular anaerobic digester is influenced by a variety of interacting operational variables and conditions, which can often deviate from the ideal. Experimental investigations demonstrate that Escherichia coli and Salmonella spp. are not damaged by mesophilic temperatures, whereas rapid inactivation occurs by thermophilic digestion. A hydraulic, biokinetic and thermodynamic model of pathogen inactivation during anaerobic digestion showed that a 2 log 10 reduction in E. coli (the minimum removal required for agricultural use of conventionally treated biosolids) is likely to challenge most conventional mesophilic digesters, unless strict maintenance and management practices are adopted to minimise dead zones and by-pass flow. Efficient mixing and organic matter stabilisation are the main factors controlling the rate of inactivation under mesophilic conditions and not a direct effect of temperature per se on pathogenic organisms

Anaerobic digestion of agricultural and other substrates--implications for greenhouse gas emissions.

Science.gov (United States)

Pucker, J; Jungmeier, G; Siegl, S; Pötsch, E M

2013-06-01

The greenhouse gas (GHG) emissions, expressed in carbon dioxide equivalents (CO2-eq), of different Austrian biogas systems were analyzed and evaluated using life-cycle assessment (LCA) as part of a national project. Six commercial biogas plants were investigated and the analysis included the complete process chain: viz., the production and collection of substrates, the fermentation of the substrates in the biogas plant, the upgrading of biogas to biomethane (if applicable) and the use of the biogas or biomethane for heat and electricity or as transportation fuel. Furthermore, the LCA included the GHG emissions of construction, operation and dismantling of the major components involved in the process chain, as well as the use of by-products (e.g. fermentation residues used as fertilizers). All of the biogas systems reduced GHG emissions (in CO2-eq) compared with fossil reference systems. The potential for GHG reduction of the individual biogas systems varied between 60% and 100%. Type of feedstock and its reference use, agricultural practices, coverage of storage tanks for fermentation residues, methane leakage at the combined heat and power plant unit and the proportion of energy used as heat were identified as key factors influencing the GHG emissions of anaerobic digestion processes.

PRICE GENERATING PROCESS AND VOLATILITY IN NIGERIAN AGRICULTURAL COMMODITIES MARKET

Directory of Open Access Journals (Sweden)

Osaihiomwan Ojogho

2015-10-01

Full Text Available The literature on agricultural commodity price volatility in Nigeria has constantly reflected that an excessive price movement is harmful for both producers and consumers, particularly for those who are not able to cope with that new source of economic uncertainty. It has also raised an extensive debate on the main determinants behind the large agricultural commodity price swings observed in the last years without recourse for the price generating process. To narrow this gap, the study examined the price generating process and volatility in the Nigerian agricultural commodities market using secondary data for price series on meat, cereals, sugar, dairy and aggregate food for the period of January 1990 to February 2014. The data were analysed using the linear Gaussian State-Space (SS model. The results of the descriptive statistics showed that the coefficients of variation for cereals (39.88%, food (32.65% and dairy price (43.08% were respectively higher during the overall time period (January 1990 to February 2014 than during the first (January 1990 to January 2002 and second (February 2002 to February 2014 sub-time periods. The results of the inferential statistics showed that authoregressive moving average (ARMA model is the most selected Nigeria agricultural commodity price generating model for the time periods, that a unit increase in the past price state of cereals, dairy, sugar, meat and aggregate food would increase the future price of sugar, meat and aggregate food by N0.14, N0.28 and N0.15 respectively but decrease future price of cereals and dairy by about N1.00 and N0.21 respectively, and that the one-step ahead predicted value for the first out-ofsample period for cereals, meat, dairy and sugar price were 6317.86, 10.24 and 2.06 respectively. The Nigerian agricultural commodity prices have experienced high variability over the period, and such volatility, price-generating process and the determinants of the Nigerian food commodities

Full Text Available A filter bag method was used for estimating apparent dry matter (DM digestibility, apparent digestible organic matter in DM, true DM digestibility, true digestible organic matter in DM and Digestibility of neutral detergent fibre. The forage sample analysed comprised tree plant parts (whole, leaf and stem of alfalfa (Medicago sativa, one degree of particle breakdown (1 mm sieve size at miliing and two field replicates at Agricultural Research and Developement Station (ARDS Șimnic-Craiova. Rumen fluid was used from two cannulated dairy cows. The use of filter bags can give acceptable results for the in vitro digestibility of forages. The escape of soluble matter from bags with samples high in solubles could influence the microbial population and hence increase cell wall degradation in bags with samples low in soluble matter, if  all are in the same incubation vessel.

Microalgae treatment removes nutrients and reduces ecotoxicity of diluted piggery digestate.

Science.gov (United States)

Franchino, Marta; Tigini, Valeria; Varese, Giovanna Cristina; Mussat Sartor, Rocco; Bona, Francesca

2016-11-01

Liquid digestate is considered as an important by-product of anaerobic digestion of agriculture wastes. Currently, it is very often directly spread on local agricultural land. Yet recently concerns on its environmental risk of this processing has begun to rise. On the other hand, investigations on the effectiveness of microalgae for wastewater treatment have started to consider also this complex matrix. In this study, we cultured the green alga Chlorella vulgaris in diluted digestate coming from the anaerobic digestion of pig slurry and corn, with the aim to significantly reduce its toxicity and its very high nutrient concentration. For this purpose, a battery of toxicity tests composed of four acute and two chronic bioassays was applied after the alga cultivation. Results were compared with those obtained in the initial characterization of the digestate. Results show that highly diluted piggery digestate can be a suitable medium for culturing microalgae, as we obtained a high removal efficiency (>90%) for ammonia, total nitrogen and phosphate, though after a few days phosphorus limitation occurred. Toxicity was significantly reduced for all the organisms tested. Possible solutions for optimizing this approach avoiding high dilution rates are discussed. Copyright © 2016 Elsevier B.V.

Prospects of Anaerobic Digestion Technology in China

Institute of Scientific and Technical Information of China (English)

无

2007-01-01

As the world's largest developing country, China must face the problem of managing municipal solid waste, and the challenge of organic waste disposal is even more serious. Considering the characteristics of traditional waste disposal technologies and the subsequent secondary pollution, anaerobic digestion has various advantages such as reduction in the land needed for disposal and preservation of environmental quality. In light of the energy crisis, this paper focuses on the potential production of biogas from biowaste through anaerobic digestion processes, the problems incurred by the waste collection system, and the efficiency of the anaerobic digestion process. Use of biogas in a combined heat and power cogeneration system is also discussed. Finally, the advantages of anaerobic digestion technology for the Chinese market are summarized. The anaerobic digestion is suggested to be a promising treating technology for the organic wastes in China.

Biogas final digestive byproduct applied to croplands as fertilizer contains high levels of steroid hormones

International Nuclear Information System (INIS)

Rodriguez-Navas, Carlos; Björklund, Erland; Halling-Sørensen, Bent; Hansen, Martin

2013-01-01

In this study we evaluate and demonstrate the occurrence of nine natural and one synthetic steroid hormone, including estrogens, androgens and progestagens in biogas final digestate byproduct (digestion liquid) commonly used as an agricultural fertilizer. We investigated two biogas sites that utilize different anaerobic digestion technologies (mesophilic and thermophilic) from swine manure and other organic wastes. Individual hormone concentration levels were observed up to 1478 ng g −1 dry weight or 22.5 mg kg −1 N with estrone and progesterone reaching highest concentration levels. Evaluation of the potential environmental burden through the application in agriculture was also assessed on the basis of predicted environmental concentrations. This study indicates that the biogas digestion process does not completely remove steroid hormones from livestock manure and use of final digestate byproduct on croplands contributes to the environmental emission of hormones. -- Eight steroid hormones were found in biogas digestate byproduct in the ng g −1 dm levels. Anaerobic digestion processes do not completely remove steroid hormones from organic waste residues

Monitoring of full-scale hydrodynamic cavitation pretreatment in agricultural biogas plant.

Garuti, Mirco; Langone, Michela; Fabbri, Claudio; Piccinini, Sergio

2018-01-01

The implementation of hydrodynamic cavitation (HC) pretreatment for enhancing the methane potential from agricultural biomasses was evaluated in a full scale agricultural biogas plant, with molasses and corn meal as a supplementary energy source. HC batch tests were run to investigate the influence on methane production, particle size and viscosity of specific energy input. 470kJ/kgTS was chosen for the full-scale implementation. Nearly 6-months of operational data showed that the HC pretreatment maximized the specific methane production of about 10%, allowing the biogas plant to get out of the fluctuating markets of supplementary energy sources and to reduce the methane emissions. HC influenced viscosity and particle size of digestate, contributing to reduce the energy demand for mixing, heating and pumping. In the light of the obtained results the HC process appears to be an attractive and energetically promising alternative to other pretreatments for the degradation of biomasses in biogas plant.

The Effect of Agricultural Growing Season Change on Market Prices in Africa

to plan effective adaptation strategies. Remote sensing data can also provide some understanding of the spatial extent of these changes and whether they are likely to continue. Given the agricultural nature of most economies on the African continent, agricultural production continues to be a critical determinant of both food security and economic growth (Funk and Brown, 2009). Crop phenological parameters, such as the start and end of the growing season, the total length of the growing season, and the rate of greening and senescence are important for planning crop management, crop diversification, and intensification. The World Food Summit of 1996 defined food security as: "when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life". Food security roughly depends on three factors: 1) availability of food; 2) access to food and 3) appropriate use of food, as well as adequate water and sanitation. The first factor is dependent on growing conditions and weather and climate. In a previous paper we have investigated this factor by evaluating the effect of large scale climate oscillation on land surface phenology (Brown et al., 2010). We found that all areas in Africa are significantly affected by at least one type of large scale climate oscillations and concluded that these somewhat predictable oscillations could perhaps be used to forecast agricultural production. In addition, we have evaluated changes in agricultural land surface phenology over time (Brown et al., 2012). We found that land surface phenology models, which link large-scale vegetation indices with accumulated humidity, could successfully predict agricultural productivity in several countries around the world. In this chapter we are interested in the effect of variability in peak timing of the growing season, or phenology, on the second factor of food security, food access. In this chapter we want to determine if there is a link between market prices

Speculation and volatility spillover in the crude oil and agricultural commodity markets: A Bayesian analysis

International Nuclear Information System (INIS)

Du Xiaodong; Yu, Cindy L.; Hayes, Dermot J.

2011-01-01

This paper assesses factors that potentially influence the volatility of crude oil prices and the possible linkage between this volatility and agricultural commodity markets. Stochastic volatility models are applied to weekly crude oil, corn, and wheat futures prices from November 1998 to January 2009. Model parameters are estimated using Bayesian Markov Chain Monte Carlo methods. Speculation, scalping, and petroleum inventories are found to be important in explaining the volatility of crude oil prices. Several properties of crude oil price dynamics are established, including mean-reversion, an asymmetry between returns and volatility, volatility clustering, and infrequent compound jumps. We find evidence of volatility spillover among crude oil, corn, and wheat markets after the fall of 2006. This can be largely explained by tightened interdependence between crude oil and these commodity markets induced by ethanol production.

Climate Change and Agriculture: Can market governance mechanisms reduce emissions from the food system fairly and effectively?

Energy Technology Data Exchange (ETDEWEB)

Garnett, Tara

2012-05-15

Climate and agriculture are inextricably linked: the climate affects agricultural production and is itself affected by agricultural emissions. Agriculture is responsible for 30 per cent of global greenhouse gas emissions. How agriculture is practised therefore has significant potential for mitigating climate change, for providing food security and for improving the livelihoods of millions of food producers worldwide. There is growing interest in the use of market governance mechanisms for tackling climate change by giving the financial incentives to make the kinds of changes that are required. But how widely are these mechanisms being used in agriculture, and are they effective in reducing emissions? What impact do they have on adaptation and other aspects of sustainable development? Are they able to balance the competing demands of producers and consumers, the environment and food security? The key messages emerging from this study are that economic measures have a vital part to play within this regulatory context, but they need to be designed with care. To be effective, emissions from food production and consumption must be addressed together. If not, emissions reduced in one region will simply be displaced elsewhere. A balance needs to be struck by applying a mix of approaches – regulatory, economic, voluntary, and information: no single measure will be effective in achieving emissions reductions on its own. 'Soft' measures, such as voluntary agreements and information have a part to play in providing an enabling context for action, but they must be backed up by 'harder' regulatory or economic measures. Regulation, in the form of a cap on emissions, is a prerequisite for other market governance measures to function well. To be effective, MGMs need to consider the social, cultural and economic context within which they operate.

Performance of farmers in the future stock market in agricultural sector

Paulo Ricardo Lima

2013-03-01

Full Text Available This study aimed to evaluate the performance of the Coopermibra associated members related to agricultural contracts future. The study was carried in the municipality of Campo Mourão, State of Paraná, Brazil, through a descriptive and qualitative method. The sample consisted of 40 cooperative members, who were interviewed in September/2008 during on-farm visits together technical assistants or during farmers´ visits to the Cooperative. It was observed that 80% of the farmers perform early sales in the Cooperative branch. Among them, who can achieve a higher level of good decision (67.5%, are those that follow daily prices. The Cooperative works as an intermediary between the farmers and BM&F BOVESPA stock market because it has offered contracts to farmers for setting the price at the future at it branch, but it does not provide for the cooperative members a way to act directly in the market for derivatives. Such situation does not prevent the farmers to hold both types of contracts.

Agriculture is a hazardous industry, yet there are few regulations on the ages at which children may engage in farm work. Local agricultural market producers (LAMPs) are a growing subset of farmers within "sustainable agriculture" who engage in direct-to-consumer and direct-to-retailer enterprises. This study explores the occupational health and safety perceptions of parents and children for children who work on their families' LAMP farms. In-depth interviews were conducted with 12 parent-child dyads from LAMP farms in Illinois and North Carolina. Four themes emerged from these 24 interviews; parents and children perceived that: (1) the nature of small farms makes them safer than industrial agricultural operations; (2) child safety on farms is common sense; (3) avoiding hazardous tasks keeps children safe; and (4) parents know best (compared to regulations) about ways to keep their children safe. Some of these themes echo the results of earlier studies conducted with more conventional farms. Further research is needed to develop programs to improve child occupational safety on LAMP farms.

Anaerobic digestion has become an established and proven technology for the treatment of solid wastes. Co-digestion offers several possible ecological, technology and economical advantages. Anaerobic co-digestion can increase CH{sub 4} production of manure diesters in a 50-200% according to the operation conditions and the co-substrates used. Last September 2007, PROBIOGAS project started up with the objective of improving the production and use of biogas from co-digestion of farming, agricultural and industrial waste. Our research group takes part in the study of co-digestion of swine manure firstly with tuna fish waste and secondly with glycerine (bio diesel production waste). (Author)

Full Text Available Introduction: Agriculture as one of old sectors of economy has been important role in the supply food for peoples and raw materials. Globalization causes rapid growth of world trade and reduces information and communications costs. Globalization and rapid growth of trade increases the potential benefits of trade for agriculture from various aspects. The potential benefits of trade for agriculture increases from three aspects. Direct increase in the domain of agricultural sector activities for competition in the global market results in the benefits of access to global markets. This is especially true in cases where there is comparative advantage and the indirect effects of increased global trade on non-agricultural sectors that cause the domestic demand for food change from qualitative and quantitative aspects, are the benefits of this event. However, during the process of globalization, how to influence prices in different markets, including the impact of world prices on domestic prices is an important issue in trade policy analysis. During this process domestic prices are directly related to world prices. With this approach, the main objective of this study is to examine the effect of world price transfers to domestic markets for sensitive and certain agricultural products in Iran during 1360-91. Materials and Methods: To achieve this goal in this study, the Armington and the foreign currency elasticity of ten selected agricultural products in Iran including wheat, barley, rice, corn, soybean meal, vegetable oil (soybean and sunflower, sugar, eggs, poultry and beef, have been estimated and examined using Autoregressive Distribution lag Model (ARDL. In order to investigate speed of adjustment or in other words the speed of movement towards equilibrium, typically the error correction model (ECM is used. Existence of cointegration or in other words, long term relationship between a set of economic variables provide the basis for the use of error

Impacts on irrigated agriculture of changes in electricity costs resulting from Western Area Power Administration's power marketing alternatives

International Nuclear Information System (INIS)

Edwards, B.K.; Flaim, S.J.; Howitt, R.E.; Palmer, S.C.

1995-03-01

Irrigation is a major factor in the growth of US agricultural productivity, especially in western states, which account for more than 85% of the nation's irrigated acreage. In some of these states, almost all cropland is irrigated, and nearly 50% of the irrigation is done with electrically powered pumps. Therefore, even small increases in the cost of electricity could have a disproportionate impact on irrigated agriculture. This technical memorandum examines the impacts that could result from proposed changes in the power marketing programs of the Western Area Power Administration's Salt Lake City Area Office. The changes could increase the cost of power to all Western customers, including rural municipalities and irrigation districts that rely on inexpensive federal power to pump water. The impacts are assessed by translating changes in Western's wholesale power rate into changes in the cost of pumping water as an input for agricultural production. Farmers can adapt to higher electricity prices in many ways, such as (1) using different pumping fuels, (2) adding workers and increasing management to irrigate more efficiently, and (3) growing more drought-tolerant crops. This study projects several responses, including using less groundwater and planting fewer waterintensive crops. The study finds that when dependence on Western's power is high, the cost of power can have a major effect on energy use, agricultural practices, and the distribution of planted acreage. The biggest percentage changes in farm income would occur (1) in Nevada and Utah (however, all projected changes are less than 2% of the baseline) and (2) under the marketing alternatives that represent the lowest capacity and energy offer considered in Western's Electric Power Marketing Environmental Impact Statement. The aggregate impact on farm incomes and the value of total farm production would be much smaller than that suggested by the changes in water use and planted acreage

Sewage sludge management is an important element of environmental protection. Composting and anaerobic digestion are the biological conversion methods for sewage sludge management. Mass and volume reduction is a result of a properly composted process. Solid fraction of digested pulp can be use as co-substrate, because it is good structural material. The aim of the study was to determine the possibility of composting sewage sludge with a solid fraction of digestate. The compost mix consisted of 25 kilograms of sewage sludge and 20 kilograms solid fraction of digestate in fresh mass. The experiment was carried out in laboratory conditions. Bioreactors of 165 dm3 volume were used. The experiment included two stages. Stage I took place in bioreactors and lasted until the cooling phase of the compost was complete. Stage II included compost maturation for a period of eight months (to 287 day of composting). The reduction of mass obtained at the end of Stage I amounted 30.2%. At the end of Stage II, it was 86.7% relative to the initial weight of the compost. The maximum value of temperature was 75.1°C. Studies have shown that sludge with a solid fraction of digestate can be a suitable substrate for composting with sewage sludge.

AGRICULTURE AND AGRICULTURAL COOPERATIVES IN JAPAN - A MODEL FOR COOPERATIVIZATION OF AGRICULTURE FROM ROMANIA

Directory of Open Access Journals (Sweden)

Remus Gherman

2016-10-01

Full Text Available Japan's agriculture provides only a part from the population's needs, in caloric terms Japan must impute 60% of foods. Arable land are few, but are worked very performant, rice being the main crop together with cotton, citrus, sugarcane, wheat, potato, soybean, sugar beet, other vegetables. Widely is practiced sericulture and fisheries, Japan being one of the leading producers of silk from the world and having over 600 ports specialized for fishing. Japanese agriculture has remained behind the industry and services, this trend being manifested after the very high economic growth from 1960-1970. The main focus of the movements from the Japanese cooperative system is represented by the creation of large specialized farms through the replacing of the traditional ones. The most important task of agricultural cooperatives from Japan is meeting the consumption needs of its members. Integrated leadership of Japanese cooperatives of farmers act at all levels, primary, at prefecture level and at national level. Contractual relationships play a decisive role in the integration of Japanese farmers. In Japan there are about 840 agricultural cooperatives very well organized with a balanced planning and efficiently conducted, agricultural cooperative MIKABI being the most developed, mainly focused on the production of mandarins. In Japan there are three large distribution centers of agricultural products, 29 distribution markets controlled by the prefecture and 1,000 local markets. Organization of cooperatives is the pyramid system on three levels: local, prefecture and national (National Federation of Agricultural Cooperatives.

Implications of Climate Volatility for Agricultural Commodity Markets in the Presence of Biofuel Mandates

Science.gov (United States)

Verma, M.; Diffenbaugh, N. S.; Hertel, T. W.; Beckman, J.

2011-12-01

In presence of bio-fuels, link between energy and agricultural commodity markets has become more complex. An increase in ethanol production to minimum 15bn gallons a year - Renewable Fuel Standard (RFS) and current technically permissible maximum 10% blending limit - Blend Wall (BW); make the link even stronger. If oil prices in future do not rise significantly from their current levels, this minimum production requirement would likely be binding. In such a scenario any fluctuation in crop production will have to be absorbed by the non-ethanol usage of the crop and would translate into crop prices adjusting to clear the markets and therefore the commodity prices will be more volatile. At high oil prices it is possible that the BW may become binding, severing the link between oil prices and commodity prices as well, potentially leading to higher price volatility. Hertel and Beckman (2010) find that, with both RFS and BW simultaneously binding, corn price volatility due to supply side shocks (which could arise from extreme climate events) could be more than 50% as large as in the absence of bio-fuel policies. So energy markets are important determinants of agricultural commodity price volatility. This proposal intends to introduce the increased supply side volatility on account of climate change and volatility, in the framework. Global warming on account of increased GHG concentrations is expected to increase the intensity and frequency of hot extremes in US (Diffenbaugh et al. 2008) and therefore affect corn yields. With supply shocks expected to increase, binding RFS and BW will exacerbate the volatility, while if they are non-binding then the price changes could be cushioned. We propose to model the impacts of climate changes and volatility on commodity prices by linking three main components - a. Projections for change in temperature and precipitation using climate model b. A statistical model to predict impacts of change in climate variable on corn yields in US

Life-cycle energy production and emissions mitigation by comprehensive biogas-digestate utilization.

Science.gov (United States)

Chen, Shaoqing; Chen, Bin; Song, Dan

2012-06-01

In the context of global energy shortages and climate change, developing biogas plants with links to agricultural system has become an important strategy for cleaner rural energy and renewable agriculture. In this study, a life-cycle energy and environmental assessment was performed for a biogas-digestate utilization system in China. The results suggest that biogas utilization (heating, illumination, and fuel) and comprehensive digestate reuse are of equal importance in the total energy production of the system, and they also play an important role in systemic greenhouse gas mitigation. Improvement can be achieved in both energy production and emissions mitigation when the ratio of the current three biogas utilization pathways is adjusted. Regarding digestate reuse, a tradeoff between energy and environmental performance can be obtained by focusing on the substitution for top-dressing, base fertilizers, and the application to seed soaking.

Wang, G.

2010-12-15

In this thesis, the feasibility of utilizing energy crops (willow and miscanthus) and agriculture residues (wheat straw and corn stalker) in an anaerobic digestion process for biogas production was evaluated. Potential energy crops and agriculture residues were screened according to their suitability for biogas production. Moreover, pretreatment of these biomasses by using wet explosion method was studied and the effect of the wet explosion process was evaluated based on the increase of (a) sugar release and (b) methane potential when comparing the pretreated biomass and raw biomass. Ensiling of perennial crops was tested as a storage method and pretreatment method for enhancement of the biodegradability of the crops. The efficiency of the silage process was evaluated based on (a) the amount of biomass loss during storage and (b) the effect of the silage on methane potential. Co-digestion of raw and wet explosion pretreated energy crops and agriculture residues with swine manure at various volatile solids (VS) ratio between crop and manure was carried out by batch tests and continuous experiments. The efficiency of the co-digestion experiment was evaluated based on (a) the methane potential in term of ml CH4 produced per g of VS-added and (b) the amount of methane produced per m3 of reactor volume.

Implementation of co-digestion and sludge management systems in Portugal

Energy Technology Data Exchange (ETDEWEB)

Di Berardino, Santino [INETI/DER, Lisboa (Portugal)

2006-07-01

A solution based on sludge and Olive oil mill effluent (OME) co-digestion, coupled with a management plan, has been implemented, to treat and dispose safely, the mixed residues, into the natural forest and agricultural land. The mixture of up to 25% OME to the sludge improved anaerobic degradation of phenols and fats. High density fat compounds, present in OME, enhanced aggregation, settling and acetoclastic activity of anaerobic sludge. The full scale unit, obtained by modification of a cold digester, allowed to set-up a low capital cost system. The system produced large quantity of biogas and electric energy. Anaerobic degradation of the mixture improved fertilizing properties, making feasible land application of the digested mixture. Regional plan based in Geographical Information System (GIS) selected 800 ha of adequate land area for application near the WWTP. The experience is technically and economically successful. Main incomes are provided by energy use and OME charge. Sludge application in local agriculture does not generate any income, but eliminated landfill costs and reduced transportation costs.

Soil incorporation of digestate represents a common practice to dispose the solid residues from biogas producing plants. Although the digestate constitutes a residual biomass rich in partially decomposed organic matter and nutrients, whose content is often highly variable and unbalanced, its potential fertilizer value can vary considerably depending on the recipient soil properties. The aim of the work was to assess short-term changes in the fertility status of two contrasting agricultural soils in Southern Italy (Calabria), olive grove on a clay acid soil (Typic Hapludalfs) and citrus grove on a sandy loam slightly calcareous soil (Typic Xerofluvents), respectively located along the Tyrrhenian or the Ionian coast. An amount of 30 t ha-1 digestate was incorporated into the soil by ploughing. Unamended tilled soil was used as control. The following soil physical, chemical and biochemical variables were monitored during the experimental period: aggregate stability, pH, electrical conductivity, organic C, total N, Olsen-P, N-NH4+, N-NO3-, microbial biomass carbon (MBC), microbial biomass nitrogen (MBN) and the mineralization quotient (qM). Moreover, in the olive grove soil CO2 emissions have been continuously measured at field scale for 5 months after digestate incorporation. Digestate application in both site exerted a significant positive effect on soil aggregate stability with a greater increase in clay than in sandy loam soil. Over the experimental period, digestate considerably affected the nutrient availability, namely Olsen-P, N-NH4+, N-NO3-, along with the electrical conductivity. The soil type increased significantly the soil N-NH4+ content, which was always higher in the olive than in citrus grove soil. N-NO3- content was markedly increased soon after the organic amendment, followed by a seasonal decline more evident in the sandy loam soil. Moreover, soil properties as CaCO3 content and the pH selectively affected the Olsen-P dynamics. No appreciable

Anaerobic digestion has been practically applied in agricultural and industrial waste treatment and recognized as an economical-effective way for food waste disposal. This paper presented an overview on the researches about anaerobic digestion of food waste. Technologies (e.g., pretreatment, co-digestion, inhibition and mitigation, anaerobic digestion systems, etc.) were introduced and evaluated on the basis of bibliometric analysis. Results indicated that ethanol and aerobic prefermentation were novel approaches to enhance substrates hydrolysis and methane yield. With the promotion of resource recovery, more attention should be paid to biorefinery technologies which can produce more useful products toward zero emissions. Furthermore, a technological route for food waste conversion based on anaerobic digestion was proposed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Mathematical tool to size rural digesters

Florentino Helenice de Oliveira

2003-01-01

Full Text Available Anaerobic digesters have been highlighted due to the current energy crisis and its consequent search for alternative energy sources, allied to the intense process of livestock farming and agriculture modernization, which besides demanding a lot of energy, produces a great amount of crop and animal residues, most of the times generating sanitary problems. The aim of this work is to provide a mathematical tool to establish parameters for projects of construction of rural digesters, considering the response to energy demand, the suitability of the dimensions of the systems, yield factors and the guarantee of functionality. Non-linear optimization models, of easy resolution, for the three main types of rural digesters were formulated in this way. With the resolution of these models one can determine the height and the diameter that lead to a minimum volume for each type, so reducing the necessary amount of masonry and, consequently, diminishing the cost.

This investigation studied the application of digester effluent from co-digestion of pig manure and spent mushroom substrate as a fertilizer for leaf mustard planting and as feed for Tilapia fish growing. The fish raising experiment was set up in 1 × 1 × 1 m hapa conditions (triplicate for each treatment) with the density of 10 individiual per hapa; the fish weight and length were measured every 10 days for 50 continuous days. The leaf mustard was planted in real conditions at farmer's garden with normal cultivation style, and the weight and length of the plant were measured four times during the growing period. The study result shows that the harvest yield of leaf mustard fertilized by the digester effluent was 5.4 times higher than that by an inorganic fertilizer (IF). In addition to its contribution to a higher yield, the digester effluent accelerated the flower formation and shortened cultivation duration. For Tilapia fish culture, the growing rate of fish in the treatments supplied with 50% digester effluent + 50% commercial food (CF) was not significantly different in comparison to the fish cultivation with 100% CF. The result strongly confirms that the digester effluent from a co-digestion biogas plant of pig dung and spent mushroom compost is possible to be used as an organic fertilizer well for not only vegetable planting but also fish culture.

Green House Gas Control and Agricultural Biomass for Sustainable Animal Agriculture in Developing Countries

Directory of Open Access Journals (Sweden)

J Takahashi

2010-06-01

Full Text Available Important green house gases (GHG attributed to animal agriculture are methane (CH4 and nitrous oxide (N2O, though carbon dioxide (CO2 contributes almost half of total greenhouse effect. Rumen CH4 production in an enteric fermentation can be accounted as the biggest anthropogenic source. Some of prebiotics and probiotics have been innovated to mitigate rumen CH4 emission. The possible use of agricultural biomass consisted of non-edible parts of crop plants such as cellulose and hemi cellulose and animal wastes was proposed as a renewable energy and nitrogen sources. The ammonia stripping from digested slurry of animal manure in biogas plant applied three options of nitrogen recycling to mitigate nitrous oxide emission. In the first option of the ammonia stripping, the effect of ammonolysis on feed value of cellulose biomass was evaluated on digestibility, energy metabolism and protein utilization. Saccharification of the NH3 treated cellulose biomass was confirmed in strictly anaerobic incubation with rumen cellulolytic bacteria, Ruminoccous flavefaciens, to produce bio-ethanol as the second option of ammonia stripping. In an attempt of NH3 fuel cell, the reformed hydrogen from the NH3 stripped from 20 liter of digested slurry in thermophilic biogas plant could generate 0.12 W electricity with proton exchange membrane fuel cell (PEM as the third option.

Stochastic modelling of the economic viability of on-farm co-digestion of pig manure and food waste in Ireland

2017-01-01

Highlights: •Assessed economic viability of on-farm manure mono- and co-digestion. •Assessed three farm sizes: 521 sows; 2607 sows; and 5214 sows. •Mono-digestion of manure alone not economically viable. •Co-digestion viable on small farms as food waste likely to be sourced. •Viability on larger farms dependent on securing sufficient food waste. -- Abstract: The majority of studies analysing the economic potential of biogas systems utilise deterministic models to assess the viability of a system using fixed inputs. However, changes in market conditions can significantly affect the viability of biogas plants, and need to be accounted for. This study assessed the economic potential of undertaking on-farm anaerobic co-digestion of food waste (FW) and pig manure (PM) using both deterministic and stochastic modelling approaches. The financial viability of three co-digestion plants sized to treat PM generated from 521, 2607 and 5214 sow integrated units was assessed. Under current market conditions the largest co-digestion scenario modelled was found to be unviable. Stochastic modelling of four key input variables (FW availability, renewable electricity tariff, gate fees and digestate disposal costs) was undertaken to assess the sensitivity of project viability to changes in market conditions. Due to the high likelihood of accessing sufficient FW, the smallest co-digestion scenario was found to be the least sensitive to any future changes in market conditions. Due to its potential to treat greater amounts of FW than the smallest scenario, a co-digestion plant designed for a 2607 sow farm had the highest revenue generating potential under optimal market conditions; however, it was more sensitive to changes in FW availability than the smaller scenario. This study illustrates the need for farm-based biogas plant projects to secure long-term, stable supplies of co-substrates and to size plants’ capacity based on the availability of the co-substrates which drive

Capsule-type pe biogas digester: low-cost and environment friendly system

International Nuclear Information System (INIS)

Ahmad, S.; Khan, M.A.; Aslam, M.; Hussain, Z.

2005-01-01

The Indian model of the biogas digester has been introduced in the country during the last three decades, whereas the Chinese dome-type design could not be introduced due to the skills required for construction of this digester. The other problem associated with Chinese dome-type digester is that large quantities of solid waste are needed to fill the digester. The Chinese dome-type digester constructed on experimental basis could not perform satisfactorily. The Indian Model, although popular in the country, is not environment friendly and is of high cost, both in terms of capital investment and 0 and M. It creates quite dirty environment around the digester due to the free movement of slurry. It also creates problems of mosquitoes, as the environment. is conducive for their breeding. Taking into consideration, these limitations, design of polyethylene capsule-type digester (with black carbon and UV stabilizers) was developed, using water tanks normally constructed for domestic water storage by the local plastic companies. Modification was made in the PE water tank and one of the local companies collaborated to manufacture the capsule-type digester. Solid waste is introduced from the top, whereas the slurry can be disposed from the bottom through a controlled valve. Thus input of solid waste and slurry-disposal is now within the choice of the owner. The slurry can be disposed into a tank, where it can be composted to reduce the pH, before its use for agriculture. The PE capsule-type black-color digester is also attractive for increasing the temperature of the digester due to black body absorption. The production of gas during summer season might take a few days, whereas additional greenhouse effect during winter can raise the temperature by 10 degree C. Hence, this digester is more suitable for cooler regions where the Indian model is not successful. The design is modular in nature; therefore linking additional modules in series can increase the capacity of biogas

The static welfare effects of the accession to the European Union on the Finnish agricultural markets

2008-12-01

Full Text Available Finland’s entry into the European Union in 1995 and the application of the Common Agricultural Policy have had major repercussions on Finland’s agriculture, which faces the major disadvantages of an unfavourable climate and farm structure. This paper attempts to measure the direct static welfare effects associated with the opening of Finnish agricultural markets for more competition. Using a standard comparative static partial equilibrium analysis in the Marshallian economic surplus framework, the welfare effects are calculated for eight major cereal and livestock commodities produced in Finland for the year 2003. The results suggest that farmers, despite the growth in direct payments, have incurred large annual welfare losses ranging from EUR 570 to EUR 600 million. Consumers, on the other hand, have gained from the accession between EUR 815 and 875 million annually.

Can anaerobic digestion of sugar beet pulp support the circular economy? a study of biogas and nutrient potential

Science.gov (United States)

Suhartini, S.; Heaven, S.; Banks, C. J.

Anaerobic digestion (AD), known as a biological process without oxygen to convert complex organic materials into biogas, is capable of processing large tonnage quantities of biomass, such as sugar beet pulp (SBP). In addition to biogas production, its use allows nutrients and organic carbon recycle back to agriculture through the spreading of digestate. Digestate still contains high amount of nutrients (N, P, K) for use as biofertiliser. The aims of this research were to determine biogas/methane potential as a baseline for comparison with performance in semi-continuous digestion, and to determine nutrient and potentially toxic elements (PTE) of digestate fractions with respect to their potential for utilisation in agriculture. The Biochemical Methane Potential (BMP) test was performed in triplicate against blank and positive controls over a period of 28 days with gas measured at regular intervals. Semi-continuous AD of SBP was operated under mesophilic and thermophilic condition for 206 and 165 days. The results indicated that SBP is a very promising feedstock for AD, with the average BMP of 0.321 l CH4 g-1 VS and biogas potential of 0.605 l g-1 VS. Under semi-continuous operation, SBP also demonstrated positive results. Digestates from mesophilic and thermophilic AD of SBP contained useful quantities of N, P and K, with an acceptable Ni concentration in accordance to limits for PTE. These results suggest that digestate has the potential to be utilised on agricultural and arable land. This study illustrated the positive effects of applying AD to the achievement of economic savings and environmental-friendly performance.

Recovering energy and nutrients from waste offers opportunities to tackle issues of energy and food security whilst simultaneously improving waste management. Waste materials from the bioenergy industry potentially contain valuable resources for use in agriculture and there is growing evidence to suggest that the use of digestate, from anaerobic digestion, and biomass ash from incineration processes could contribute to improving soil health and nutrition. The work presented here is part of the Adding Value to Ash and Digestate (AVAnD) project which looks at the impacts of digestate and ash blends on soil fertility, crop yields and soil health. Whilst increased crop productivity is one of the essential indicators of the success of these alternative soil amendments; it is important that the impacts on soil biological function is understood. Field and lab experiments were conducted with a number of different fertiliser treatments, including conventional fertiliser (urea and superphosphate), digestate from two contrasting feedstocks, ash material and ash-digestate blends. Looking across different biological scales from soil microbe to soil macro-fauna, this work examines the benefits and threats to soil biota arising from the use of ash-digestate fertilisers in agriculture. Measurements of microbial respiration and biomass (by chloroform fumigation) and community composition (by phospholipid fatty acid analysis) were made at different timescales (days/weeks). Data from these studies demonstrates that none of the soil amendments decreased microbial activity or biomass in the short term (t= 1 month). Additions of both conventional fertilisers and the fertilisers derived from waste stimulated microbial activity with significantly higher respiration observed from the digestate based treatments. Digestate-based treatments also resulted in higher soil microbial biomass and differential effects were observed between digestate amendments with and without ash. These results

Full Text Available Financial institutions present on the market become more attentive when they have to give loans to the agriculture sector. The lack of necessary guarantees the low profit registered in agricultural district, economy instability and other things had and continue to have a negative impact on the evolution of agricultural sector, this being seen as one with a high level of risk. Commercial banks use less own funds for lending to agriculture and especially when the loans are guaranteed from various funds, programs or foreign donor agencies. Farmers find it difficult to bank loans because of collateral amount required is too high. However, commercial banks in Moldova provide agricultural loans, thus increasing the economic efficiency of agriculture.

Soil carbon sequestration, carbon markets, and conservation agriculture practices: A hypothetical examination in Mozambique

Directory of Open Access Journals (Sweden)

Timoteo E. Simone

2017-09-01

Full Text Available Payments for Environmental Services (PES are relatively novel mechanisms whereby the adoption of sustainable management practices by a stakeholder is rewarded by incentives linked to external markets. Adoption of PES for conservation agricultural practices (CAPS by smallholder farmers may provide opportunities to increase household income or cover the technology costs of adoption if the carbon sequestration benefits of CAPS are quantifiable, adoption rates are accelerated and maintained, a mechanism exists whereby carbon sequestration services can be compensated, and carbon offset exchange markets are viable. This research suggests a methodology to examine a PES market for carbon offsets generated by the adoption of CAPS by farmers in Mozambique. Assuming a cumulative adoption of 60% over a 20-year period, revenue from PES market participation to CA adopters was two times higher than revenue earned when disadoption occurred midway through the simulation. Lower adoption targets are associated with higher per household returns when fertilizer rates typical to the region are increased. Establishing and maintaining a sustainable PES system in the study region would require significant investment in time and resources. The lack of on-the-ground institutions or local support for such a program would also challenge successful implementation. Finally, the programs where participant success depends on external markets, such as the hypothetical one suggested here, are subject to the ebb and flow of foreign demand for carbon offsets. Addressing these three broad constraints to a PES/CAPS program in the region would require grass-roots driven policy initiatives with buy-in at multiple social, economic, and political levels.

Marketing activities are introduced into a rational expectations model of the food marketing system. The model is used to evaluate effects of alternative marketing technologies on the distribution of the benefits of contingency markets in agriculture. Benefits depend on two parameters: the cost share of farm inputs and the elasticity of substitution between farm and nonfarm inputs in food marketing. Over a broad spectrum of technologies, consumers are likely to be the net beneficiaries and fa...

Hygiene tests in the anaerobic digestion of household refuse

Energy Technology Data Exchange (ETDEWEB)

Maier, H.; Philipp, W.; Wekerle, J.; Strauch, D.

In a pilot plant the disinfecting effect of composting the effluent of an anaerobic mesophilic digestion process of the organic fraction of household refuse was investigated. The dewatered effluent was mixed with straw as bulking material, put in not aerated windrows and aerobically composted. It was further investigated whether the influent of the digester could be disinfected with lime milk prior to the anaerobic mesophilic digestion process. For the evaluation of the disinfection salmonellas, enterococci, klebsiellas, parvo-, polio- and rotavirus were used as test agents. Temperature, total aerobic germ count, enterobacteriaceae and coliforms were also considered. The effect of lime milk in the influent on the digestion process, survival of the test bacteria and gas production was also studied. Both treatments can result in a hygienically safe product. But composting under the conditions given should not be operated during the winter period. Lime treatment of the influent results in a disinfection of the effluent which immediately can be utilized as liquid sludge in agriculture. (orig.)

A project was undertaken to examine the feasibility of treating organic wastes from Thai fruit and vegetable markets using the sequential batch anaerobic digester (SEBAR) approach. A key feature of the SEBAR system is the regular interchanging, or recirculation, of portions of leachate between each freshly filled digester and a support digester to which it is coupled until it is ready to operate independently. Leachate transfer from this support digester to the fresh waste digester provides additional alkalinity to help counteract the effects of early high acid release rates; it also helps build a balanced microbial population in the fresh waste digester. To optimize the leachate recirculation process, the effect of varying the quantities of leachate interchanged between freshly filled waste digesters and the still highly active support digesters to which they were coupled was studied. It was found that increasing the recirculation rate accelerated the onset of both waste degradation and methane production. The increasing of recirculation rate from 10% to 20% and 10% to 30% could reduce the SEBAR cycle period by approximately 7% and 22% without significant reduction in the amount of methane obtained from the systems. The methane yields were 0.0063, 0.0068 and 0.0077 l g(-1) VS added in the NEW digester per day using leachate recirculation rates of 10%, 20% and 30%, respectively. This finding has potentially important practical and economic implications for those using the SEBAR system to add value to market waste.

Full Text Available In this study Stochastic Data Envelopment Analysis method was used in order to estimate the economic efficiency of agricultural cooperatives in the Buinzahra city. Moreover, the Analytical Hierarchy Process method and Entropy criteria were used in order to prioritizate the agricultural cooperatives problems of this city in management and marketing system. The required dates were related to the years 2012-2013 during which data were collected by interviewing and completing questionnaires for 43 members of the cooperatives. The Random Sampling method and the Cochran formula were used to determine the sample size and from the Cronbach's Alpha method was used in order to evaluate the validity and reliability of the questionnaire. The results showed that the random efficiency average of agricultural cooperatives in Buinzahra city is at the low level (79 Percent and animal husbandry units have the lowest level of the efficiency. Also the results showed that inappropriate policies in the pricing and price volatility of agricultural products, the low level of services of packaging, processing, marketing and distribution of the products and the lack of long-term comprehensive planning by managers have the first, second and third ranks in the inefficiency of the management process and the marketing system of cooperatives in the study area respectively. Finally, the site locating studies before the establishment of cooperatives, providing funding and loans with low interest rates to animal husbandry units, transferring the experiences and expertise of successful cooperatives to inefficient cooperatives and strengthening and supporting the marketing system in order to resolve the problems facing the agricultural cooperatives of city Buinzahra were proposed based on the results obtained.

Learning achievements of farmers during the transition to market-oriented organic agriculture in rural Uganda

Directory of Open Access Journals (Sweden)

Amos Owamani

2010-04-01

Full Text Available Organic agriculture requires farmers with the ability to develop profitable agro-enterprises on their own. By drawing on four years of experiences with the Enabling Rural Innovation approach in Uganda, we outline how smallholder farmers transition to organic agriculture and, at the same time, increase their entrepreneurial skills and competences through learning. In order to document this learning we operationalised the Kirkpatrick learning evaluation model, which subsequently informed the collection of qualitative data in two study sites. Our analysis suggests that the Enabling Rural Innovation approach helps farmers to develop essential capabilities for identifying organic markets and new organic commodities, for testing these organic commodities under varying organic farm management scenarios, and for negotiating contracts with organic traders. We also observed several obstacles that confront farmers’ transition to organic agriculture when using the Enabling Rural Innovation approach. These include the long duration of agronomic experimentation and seed multiplication, expensive organic certification procedures and the absence of adequate mechanism for farmers to access crop finance services. Despite prevailing obstacles we conclude that the Enabling Rural Innovation approach provides a starting point for farmers to develop entrepreneurial competences and profitable agro-enterprises on their own.

Dual Approach to the Study of Land Market Functioning

Directory of Open Access Journals (Sweden)

Liliya Oganesovna Oganesyan

2015-12-01

Full Text Available The article reveals the essence, the structural elements and features of the mechanism of functioning of the market of agricultural land. The authors present the supplementing idea on the structural dichotomy of the agricultural land market. In contrast to neoclassical approaches, it is proposed to explore the market based on its structural dichotomy – market property rights and market rights of management. In this context, the mechanism of functioning of agricultural lands market performs the function of a basic element in the system of land relations to ensure market circulation of agricultural land through alienation and assign full or partial rights of land ownership. The use of the institutional approach to the study of market structures justifies the dual nature of the mechanism of functioning of the market of agricultural land due to the fact that on the one hand, the market is slow and limited in the market space of the rare economic good or factor of production, and on the other hand, it is a dynamic institutional and economic system within which the specification of property rights to land is implemented. The structure of the mechanism of functioning and development of agricultural land market is considered as a system of interrelated and interacting elements of state regulation and market self-regulation, based on the principles of coordination and harmonization of personalized economic interests and market law of supply and demand. The combination of elements of market self-regulation and state regulation allows in practice to justify the choice of model combinations of stable and changing elements of the mechanism. This combination complies with the institutional conditions for the functioning of the market of agricultural land considering the dominance of regulated sustainable standards at the market of property rights and in the frames of informal institutions at the market of the management rights.

Highlights: • TetQ had the highest relative abundance and tetG was the most persistent gene. • The anaerobic digestion has no effective removal of most ARGs. • The abundance of ARGs in soils and fishpond was higher than that of control system. • Positive correlations were observed between the total ARGs and TN, TP and TOC. - Abstract: This study aims to determine abundance and persistence of antibiotics and antibiotic resistance genes (ARGs) in eco-agricultural system (EAS), which starts from swine feces to anaerobic digestion products, then application of anaerobic digestion solid residue (ADSR) and anaerobic digestion liquid residue (ADLR) to the soil to grow ryegrass, one of swine feed. Oxytetracycline had the highest concentration in manure reaching up to 138.7 mg/kg. Most of antibiotics could be effectively eliminated by anaerobic digestion and removal rates ranged from 11% to 86%. ARGs abundance fluctuated within EAS. TetQ had the highest relative abundance and the relative abundance of tetG had the least variation within the system, which indicates that tetG is persistent in the agricultural environment and requires more attention. Compared to the relative abundance in manure, tetC and tetM increased in biogas residue while three ribosomal protection proteins genes (tetO, tetQ, tetW) decreased (p 0.05). Most ARGs in downstream components (soils and fishpond) of EAS showed significantly higher relative abundance than the control agricultural system (p < 0.05), except for tetG and sulI.

Above all, the consumption pattern and preference of rural consumer is changing due to the dynamic nature of marketing. However, marketers are failing to reach this largest target market of the population. This is mainly because, marketers are focusing on designing a product for urban market and when it becomes obsolete, it moves to the rural market. Indeed, it is unethical to override the marketing preference of the rural consumer. Recognizing the marketing requirements of the majority of the population would helps to bring a vibrant economic impact in the development of the nation. The present paper highlighted the major challenges and opportunities of Rural Marketing in Ethiopia, identified ways to explore the untapped Ethiopian Rural Market and identified possible recommendations and policy implications that would help to bring an improved development in the rural Ethiopia. Accordingly, the present article seeks the attention of Policy makers, Investors, Higher education curriculum developers and marketers to

Toxic fables: the advertising and marketing of agricultural chemicals in the great plains, 1945-1985.

Science.gov (United States)

Vail, David D

2012-12-01

This paper examines how pesticides and their technologies were sold to farmers and pilots throughout the midtwentieth century. It principally considers how marketing rhetoric and advertisement strategies used by chemical companies and aerial spraying firms influenced the practices and perspectives of farm producers in the Great Plains. In order to convince landowners and agricultural leaders to buy their pesticides, chemical companies generated advertisements that championed local crop health, mixture accuracy, livestock safety and a chemical-farming 'way of life' that kept fields healthy and productive. Combining notions of safety, accuracy and professionalism with pest eradication messages reinforced the standards that landowners, pilots and agriculturalists would hold regarding toxicity and risk when spraying their fields. As the politics of health changed in the aftermath of Rachel Carson's Silent Spring, these companies and aerial spraying outfits responded by keeping to a vision of agricultural health that required poisons for protection through technological accuracy.

Biogas recovery in anaerobic digestion plants for pig wastewater

International Nuclear Information System (INIS)

Collivigarelli, C.; Sorlini, S.

2001-01-01

This work deals with a monitoring of thee anaerobic digestion plants in mesophilic conditions treating pig wastewater with the aim to study the treatment efficiency and energetic aspects. A good waste stabilization is reached in all plants, as shown by the high removal efficiency of total and volatile solids and COD, mainly due to the digestion process. On the contrary, Kjeldahl nitrogen and ammonia (low) removal takes place mainly in the final storage tank, thanks to ammonia stripping. The digestion process not only produces a well stabilized wastewater, that can be more surely reused for agricultural spreading, but it offers also an important energy recovery from the biogas combustion, whose specific production varies from 0,78 to 0,99 Nm 3 t - 1 (live weight) d - 1. It is used in cogeneration plants for the combined production of thermal energy (that is reused for waste heating in the digestion tank at mesophilic conditions and for other internal utilizations) and electric energy (that is used for internal requirements while the surplus is sent into the public grid) [it

Persistence and potential Viable but Non-culturable state of pathogenic bacteria during storage of digestates from agricultural biogas plants

Directory of Open Access Journals (Sweden)

Geraldine Maynaud

2016-09-01

Full Text Available Despite the development of on-farm anaerobic digestion as a process for making profitable use of animal by-products, factors leading to the inactivation of pathogenic bacteria during storage of digestates remain poorly described. Here, a microcosm approach was used to evaluate the persistence of three pathogenic bacteria (Salmonella enterica Derby, Campylobacter coli and Listeria monocytogenes in digestates from farms, stored for later land spreading. Nine samples, including raw digestates, liquid fractions of digestate and composted digestates, were inoculated with each pathogen and maintained for 40 days at 24°C. Concentrations of pathogens were monitored using culture and qPCR methods. The persistence of L. monocytogenes, detected up to 20 days after inoculation, was higher than that of Salmonella Derby, detected for 7-20 days, and of C. coli (not detected after 7 days. In some digestates, the concentration of the pathogens by qPCR assay was several orders of magnitude higher than the concentration of culturable cells, suggesting a potential loss of culturability and induction of Viable but Non-Culturable (VBNC state. The potential VBNC state which was generally not observed in the same digestate for the three pathogens, occurred more frequently for C. coli and L. monocytogenes than for Salmonella Derby. Composting a digestate reduced the persistence of seeded L. monocytogenes but promoted the maintenance of Salmonella Derby. The effect of NH4+/NH3 on the culturability of C. coli and Salmonella Derby was also shown.The loss of culturability may be the underlying mechanism for the regrowth of pathogens. We have also demonstrated the importance of using molecular tools to monitor pathogens in environmental samples since culture methods may underestimate cell concentration. Our results underline the importance of considering VBNC cells when evaluating the sanitary effect of an anaerobic digestion process and the persistence of pathogens during

Digestibility and energetic value of agricultural wastes as affected by gamma irradiation and chemical treatments

International Nuclear Information System (INIS)

Al-Masri, M.R.

2002-01-01

Experiments were carried out to study the changes in the values of in-vitro apparent organic matter digestibility (IVOMD), metabolizable energy (ME) and net energy lactation (NEL) of wheat straw, sunflower seed shell, olive cake wood, date palm seeds and peanut shell after spraying with different concentrations of hydrobromic acid (HBr) and sodium hydroxide (NaOH) (0,3,6 ml HBr and 3,6 g NaOH/25 ml water/100 g Dm) or after exposure to various doses of gamma radiation (0, 20, 40, 60 kGy). Results indicated that, except for the date palm seeds, the chemical treatments with either HBr or NaOH significantly (P<0.05) increased IVOMD, Me and NEL values for all treated samples. The experimental agricultural wastes did not respond equally to the chemical treatments investigated, i.e. they differ in the induced increases pertaining to their IVOMD, ME and NEL. The highest changes in the studied parameters due to chemical treatments were obtained when applying the 6% concentration. There was no significant effect (P<0.05) of irradiation on IVOMD, ME and NEL values for all treated samples. Moreover, the combined treatments of irradiation and hydrobromic acid or sodium hydroxide were found to have no significant affects on the IVOMD, ME and NEL values compared to the individual chemical treatments.

Manure digestion in the Netherlands. Mestvergisting in Nederland; Tien jaar kennis en ervaring in de praktijk

1990-05-01

The experiences with digestion of effluent animal manure in the Netherlands are complemented with relevant information from other sources. Mesophylic manure digestion at farmscale is discussed. This type of manure digestion is most used in the Netherlands. With the surplus of manure in large parts of the Netherlands and the increasing awareness of the environmental issue, digestion is regularly mentioned as a manner to deal more efficiently with materials from manure and to improve the processability. Furthermore digestion offers a source of energy by way of biogas and environmental hygienic advantages, such as stench reduction and destruction of bacteria and seeds. With the modest research done so far, the agricultural and environmental effects are only quantified very superficially. These effects are not financially valued. Opposing the advantages manure digestion offers, are the relatively high investments as well as possible technical and processing problems with the system management. Given the experience with 5 existing manure digestion plants as well as other results from research and practice, the issue is thoroughly discussed, so that many problems can already be avoided in the design phase. Based on the present results, at a gas production of 18 m{sup 3} manure gas per m{sup 3} supplied (cattle) manure, a manure digestion plant is not cost-efffectively exploitable. With regard to the present price of energy of Hfl. 12.00 per GJ, the price of energy from manure gas is Hfl. 24.00-32.00 per GJ. The future of manure digestion depends on the degree to which gas production can be improved as well as the value that is assigned to agricultural and environmental aspects. For both fields an increase of value is expected in the near future. In Denmark, with adding organic matter, already double the amount of gas per kg organic matter is extracted compared to the Netherlands. (Abstract Truncated)

Engineering Digestion: Multiscale Processes of Food Digestion.

Science.gov (United States)

Bornhorst, Gail M; Gouseti, Ourania; Wickham, Martin S J; Bakalis, Serafim

2016-03-01

Food digestion is a complex, multiscale process that has recently become of interest to the food industry due to the developing links between food and health or disease. Food digestion can be studied by using either in vitro or in vivo models, each having certain advantages or disadvantages. The recent interest in food digestion has resulted in a large number of studies in this area, yet few have provided an in-depth, quantitative description of digestion processes. To provide a framework to develop these quantitative comparisons, a summary is given here between digestion processes and parallel unit operations in the food and chemical industry. Characterization parameters and phenomena are suggested for each step of digestion. In addition to the quantitative characterization of digestion processes, the multiscale aspect of digestion must also be considered. In both food systems and the gastrointestinal tract, multiple length scales are involved in food breakdown, mixing, absorption. These different length scales influence digestion processes independently as well as through interrelated mechanisms. To facilitate optimized development of functional food products, a multiscale, engineering approach may be taken to describe food digestion processes. A framework for this approach is described in this review, as well as examples that demonstrate the importance of process characterization as well as the multiple, interrelated length scales in the digestion process. © 2016 Institute of Food Technologists®

Highlights: • TetQ had the highest relative abundance and tetG was the most persistent gene. • The anaerobic digestion has no effective removal of most ARGs. • The abundance of ARGs in soils and fishpond was higher than that of control system. • Positive correlations were observed between the total ARGs and TN, TP and TOC. - Abstract: This study aims to determine abundance and persistence of antibiotics and antibiotic resistance genes (ARGs) in eco-agricultural system (EAS), which starts from swine feces to anaerobic digestion products, then application of anaerobic digestion solid residue (ADSR) and anaerobic digestion liquid residue (ADLR) to the soil to grow ryegrass, one of swine feed. Oxytetracycline had the highest concentration in manure reaching up to 138.7 mg/kg. Most of antibiotics could be effectively eliminated by anaerobic digestion and removal rates ranged from 11% to 86%. ARGs abundance fluctuated within EAS. TetQ had the highest relative abundance and the relative abundance of tetG had the least variation within the system, which indicates that tetG is persistent in the agricultural environment and requires more attention. Compared to the relative abundance in manure, tetC and tetM increased in biogas residue while three ribosomal protection proteins genes (tetO, tetQ, tetW) decreased (p < 0.05), with other genes showing no significant change after anaerobic fermentation (p > 0.05). Most ARGs in downstream components (soils and fishpond) of EAS showed significantly higher relative abundance than the control agricultural system (p < 0.05), except for tetG and sulI.

Sensitivity of Earth Wheat Markets to Space Weather: Comparative Analysis based on data from Medieval European Markets

Science.gov (United States)

Pustil'Nik, Lev

We consider a problem of the possible influence of unfavorable states of the space weather on agriculture markets through the chain of connections: "space weather"-"earth weather"- "agriculture crops"-"price reaction". We show that new manifestations of "space weather"- "earth weather" relations discovered in the recent time allow revising a wide range of the expected solar-terrestrial connections. In the previous works we proposed possible mechanisms of wheat market reaction on the specific unfavorable states of space weather in the form of price bursts and price asymmetry. We point out that implementation of considered "price reaction scenarios" is possible only for the case of simultaneous realization of several necessary conditions: high sensitivity of local earth weather in the selected region to space weather; the state of "high risk agriculture" in the selected agriculture zone; high sensitivity of agricultural market to a possible deficit of yield. Results of our previous works (I, II), including application of this approach to the Medieval England wheat market (1250-1700) and to the modern USA durum market (1910-1992), showed that connection between wheat price bursts and space weather state in these cases was absolutely real. The aim of the present work is to answer the question why wheat markets in one selected region may be sensitive to a space weather factor, while in other regions wheat markets demonstrate absolutely indifferent reaction on the space weather. For this aim, we consider dependence of sensitivity of wheat markets to space weather as a function of their location in different climatic zones of Europe. We analyze a database of 95 European wheat markets from 14 countries for the 600-year period (1260-1912). We show that the observed sensitivity of wheat markets to space weather effects is controlled, first of all, by a type of predominant climate in different zones of agricultural production. Wheat markets in the Northern and, partly, in

[Anaerobic digestion of lignocellulosic biomass with animal digestion mechanisms].

Science.gov (United States)

Wu, Hao; Zhang, Pan-Yue; Guo, Jian-Bin; Wu, Yong-Jie

2013-02-01

Lignocellulosic material is the most abundant renewable resource in the earth. Herbivores and wood-eating insects are highly effective in the digestion of plant cellulose, while anaerobic digestion process simulating animal alimentary tract still remains inefficient. The digestion mechanisms of herbivores and wood-eating insects and the development of anaerobic digestion processes of lignocellulose were reviewed for better understanding of animal digestion mechanisms and their application in design and operation of the anaerobic digestion reactor. Highly effective digestion of lignocellulosic materials in animal digestive system results from the synergistic effect of various digestive enzymes and a series of physical and biochemical reactions. Microbial fermentation system is strongly supported by powerful pretreatment, such as rumination of ruminants, cellulase catalysis and alkali treatment in digestive tract of wood-eating insects. Oxygen concentration gradient along the digestive tract may stimulate the hydrolytic activity of some microorganisms. In addition, the excellent arrangement of solid retention time, digesta flow and end product discharge enhance the animal digestion of wood cellulose. Although anaerobic digestion processes inoculated with rumen microorganisms based rumen digestion mechanisms were developed to treat lignocellulose, the fermentation was more greatly limited by the environmental conditions in the anaerobic digestion reactors than that in rumen or hindgut. Therefore, the anaerobic digestion processes simulating animal digestion mechanisms can effectively enhance the degradation of wood cellulose and other organic solid wastes.

Market opportunities for solar drying

International Nuclear Information System (INIS)

Voskens, R.G.J.H.; Out, P.G.; Schulte, B.

2000-01-01

One of the most promising applications for solar heating is the drying of agricultural products. The drying of agricultural products requires large quantities of low temperature air, in many cases, on a year-round basis. Low cost air-based collectors can provide heated air at solar collection efficiencies of 30 to 70%. In 1998/1999 a study was commissioned to better understand the technical and economic potential for solar drying of agricultural products in the world. The practical potential for solar drying was then determined for 59 crops and 22 regions. The world market for solar drying can be divided into three market segments: 1) mechanical drying T 50 deg. C; 3) sun drying. The most promising market for solar drying is generally market segment 1. For this segment the potential amount of energy displaced by solar is in between 216 770 PJ (World-wide). For Western Europe this potential is estimated between 23 88 PJ and for Eastern Europe between 7 and 13 PJ. A different market introduction strategy is required for each market segment. A total of 13 combinations of crops and regions are selected that appear to have the highest practical potential for solar drying. In the Netherlands a programme of activities was carried out by Ecofys and other organisations, to identify and develop the market potential for solar (assisted) drying of agricultural products. A promotional campaign for the use of renewable energy in the (promising) flower bulb sector is planned on a short-term basis to speed up market developments. It can be concluded that there is a large market for solar drying in the World as well as in Europe. (au)

Methane production by anaerobic digestion of biomass. Final report of innovative research program subtask, December 1977--September 1978

Energy Technology Data Exchange (ETDEWEB)

Murphy, V G

1978-10-01

It has long been known that methane is produced during the anaerobic digestion of agricultural wastes, but this potential source of fuel has not been greatly exploited in the United States. The chief reason is that anaerobic decomposition of lignocellulosic materials occurs very slowly, resulting in a need for long detention times and large digestion vessels, both of which markedly increase process costs. However, recent work at CSU has shown that pretreatment of manure fibers (an abundant agricultural waste) with saturated steam at 130 to 210/sup 0/C renders this material more susceptible to attack by microbial enzymes. The main objectives of this project were to identify the chemical events occurring during the steam treatment and to correlate these with the rate of methane generating during subsequent anaerobic digestion. The study was expected to lead to an optimal pretreatment strategy.

Techno-economic assessment of anaerobic digestion systems for agri-food wastes

Energy Technology Data Exchange (ETDEWEB)

Lau, A.; Baldwin, S.; Wang, M. [British Colombia Univ., Vancouver, BC (Canada)

2010-07-01

Activities in British Columbia's Fraser Valley generate an estimated 3 million tones of agriculture and food wastes annually, of which 85 per cent are readily available for anaerobic digestion. The potential for energy generation from biogas through anaerobic digestion is approximately 30 MW. On-farm manure-based systems represent the most likely scenario for the development of anaerobic digestion in British Columbia in the near future. Off-farm food processing wastes may be an alternative option to large centralized industrial complexes. Odour control, pathogen reduction, improved water quality, reduced greenhouse gas emissions and reduced landfill usage are among the environmental benefits of anaerobic digestion. The economical benefits include power and heat generation, biogas upgrading, and further processing of the residues to produce compost or animal bedding. This paper described a newly developed anaerobic digestion (AD) calculator that helps users regarding their investment decision in AD facilities. The calculator classifies various technology options into several major types of AD systems. It also constructs kinetic and economic models for these systems and provides a fair estimation on biogas yield, digester volume, capital cost and annual income. The calculator takes into consideration factors such as the degradability of wastes with different compositions and different operating parameters.

The modern global society faces great challenges in supply of energy and management of wastes in sustainable ways. One way of resolving the local challenges is to develop environmentally appropriate and socio economically viable biotechnological processes for converting biomass to energy. The general principles of anaerobic bio-digestion, digester design and features of bio-digestion are presented in the feature article, focusing on the prospects of utilizing cassava peels as a readily available lignocellulose feedstock for co-digestion with manure for the production of biogas and bio-fertilizer. Aside of the high cyanogenic properties, cassava peels would require pre-treatment before use as a substrate, hence, a multi-stage and high rate digestion system might be adopted in efficient digestion of cassava peels. To optimize carbon-nitrogen ratio for efficient digestion, cassava should be co-digested with manure. The socio-economic benefits of the anaerobic co-digestion technology and key policy measures to be implemented to harness bio-energy from agricultural wastes are also outlined. (au)

At the beginning of spring in the northern hemisphere, the situation in agricultural markets relaxes visibly. After the year 2012 was characterized by periods of drought in the United States and some Eastern European countries, in recent months good harvests in major producing countries in the southern hemisphere have provided that the stocks of major agricultural commodities are grown again. Thus, enough resources are still available for the supply of food and energy. There still exists land potential in Europe and on other continents for the use of bio-energy. In addition to new power plant crops, known arable crop cultures contribute to the exploration of such a potential: An example of this is the sugar beet. The view on the global supply balance in agricultural goods inter alia the major staple food rice shows that there exist large surpluses on the food markets. However, these surpluses do not benefit the hungry persons in the world. Hunger is a problem of distribution which is not associated with the growth of bio-energy.

2015-09-01

Full Text Available The paper deals with the intensification of separating the solid phase of digestate using flocculants only. The separated solid phase should subsequently be used in agriculture for fertilising. Flocculants (polyacrylamides are difficult to biodegrade. In this respect, they should not deteriorate the properties of the solid phase and the flocculant dose must be as low as possible. The research aimed to identify the optimal cationic flocculant and its application procedure which would enable a dosage that would be both economically and ecologically acceptable. We tested 21 cationic flocculants of different charge density and molecular weight and 1 mixture of two selected flocculants (Sokoflok 53 and Sokoflok 54 with the aim to discover the lowest possible dose of flocculating agent to achieve the effective aggregation of digestate particles. The lowest flocculant doses were obtained using the mixture of flocculants labelled Sokoflok 53 and Sokoflok 54 in 4:1 proportion, both of a low charge density and medium molecular weight, namely 14.54 g/kg of total solids for a digestate from the biogas plant Stonava and namely 11.80 g/kg of total solids for a digestate from the biogas plant Vrahovice. The findings also reveal that flocculation is most effective during two-stage flocculant dosing at different mixing time and intensity.

Experiments have been carried out to study the changes in the values of in vitro apparent organic matter digestibility (IVOMD) and in vitro digestible energy (IVDE) of wheat straw (WS), cotton seed shell (CSS), peanut shell (PS), soybean shell (SS), extracted olive cake (EOC) and extracted unpeeled sunflower seeds (ESS) after irradiation by various doses of gamma radiation (0, 100, 150, 200 kGy) or after spraying with different amounts of sodium hydroxide (NaOH): 0, 2, 4, and 6 g NaOH/25 ml water/100 g DM. The results indicate that there were significant increases in IVOMD and IVDE values for all irradiated samples and for sodium hydroxide treatments except for SS and ESS. Combined treatment of irradiation and sodium hydroxide resulted in a larger increase in the digestible energy than the individual treatments

Anaerobic digestion is increasingly recognized for its ability to produce renewable energy and reduce greenhouse gas emissions from livestock operations. In 2010, there were 2645 U.S. dairy farms with herd sizes large enough to support anaerobic digesters, yet only 156 systems were in operation (U.S. Environmental Protection Agency (U.S. EPA), 2010a. Market Opportunities for Biogas Recovery Systems at U.S. Livestock Facilities. AgSTAR Program; U.S. Environmental Protection Agency (U.S. EPA), 2011. Operational Anaerobic Digesters, Sorted by State (Dairy). AgSTAR Program.). This study analyzes the net present value of digester systems under alternative electricity purchase agreements and how returns are affected by standby charges, net metering policies and the use of feed-in-tariffs. In order for digester potential to be fully realized on a state or national level, changes to distributed energy policy are required. Results indicated that standby charges can reduce revenues from offsetting electricity by an average of nearly 20%. Net metering rules limit participation among larger farms and negatively affect profitability by restricting engine–generator size. Lastly, the effectiveness of a fixed price feed-in-tariff policy for digesters is significantly affected by project size differentiation. Digester energy policies are similar nationwide, making this study useful for government regulatory agencies and digester owners throughout the U.S. - Highlights: ► Anaerobic digester net present value was examined over a range of herd sizes. ► Standby charges reduce electricity sales revenues by an average of nearly 20%. ► Net metering rules reduce profitability by restricting engine–generator size. ► Feed-in-tariffs for digesters are significantly affected by project size.

2018-03-01

Full Text Available The aim of the article is to conduct an analysis of the agricultural products market in Ivano-Frankivsk region by assessing the main channels for selling products and the price level. By summarizing and analyzing the research of domestic scientists, the importance of conducting a qualitative and detailed market research in the system of intermediary activity is substantiated. Due to the results of the analysis of channels for selling agricultural products, it is revealed that intermediary structures have the largest market share. It is found that there is a tendency to increase the share of sold agricultural products to intermediaries both in Ukraine in general and in Ivano-Frankivsk region in particular. At the same time, direct sales on the market, and, therefore, direct contact with the end user, are decreasing year by year. Prospects for further research in this direction are searching for ways to reduce control over the agricultural market by intermediary structures.

2018-01-01

This study investigates the effect of ultrasonication and microwave sludge disintegration/pre-treatment techniques on the anaerobic co-digestion efficiency of wastewater sludges with olive and grape pomaces. The effects of both co-digestion and sludge pre-treatment techniques were evaluated in terms of the organic removal efficiency and the biogas production. The "co-digestion" of wastewater sludge with both types of pomaces was revealed to be a much more efficient way for the biogas production compared to the single (mono) sludge digestion. The ultrasonication and microwave pre-treatments applied to the sludge samples caused to a further increase in biogas and methane yields. Based on applied specific energies, ultrasonication pre-treatment was found much more effective than microwave irradiation. The specific energy applied in microwave pre-treatment (87,000kj/kgTS) was almost 9 times higher than that of used in ultrasonication (10,000kj/kgTS), resulting only 10-15% increases in biogas/methane yield. Co-digestion of winery and olive industry residues with pre-treated wastewater sludges appears to be a suitable technique for waste management and energy production. Copyright © 2017 Elsevier B.V.

Leonhardt, J.W.; Baer, M.; Nehring, K.

1983-01-01

Gamma and electron radiation effects on wheat straw, oat straw, barley straw, rye straw and dried green fodder are reported. In vitro and in vivo studies show that the digestibility of these agricultural by-products with high fibre content can be increased up to 80% and more at high doses. The increase of the digestibility is connected with a depolymerization of the cellulose and hemicellulose. (author)

Disinfection and physical and chemical changes in waste waters, sludge and agricultural wastes

International Nuclear Information System (INIS)

Groneman, A.F.; Oosterheert, W.F.

1980-01-01

It is of interest for agriculture to consider recycling scenarios that use undigested sludges as they contain higher concentrations of nitrogen, phosphorus and organic matter than digested sludges. Also from the point of view of waste water management, this approach is of interest because it reduces the time and number of treatments of sludges, thus resulting in technological and economic advantages. However, the utilization of this type of sludge in agriculture is restricted by the presence of human pathogens. Therefore studies concerning the disinfection efficiency of gamma irradiation in undigested sludge at pilot plant level were performed and results compared with the disinfection efficiency of this radiation treatment in digested sludge.

Digestibility and energetic value of some agricultural wastes as affected by gamma irradiation and chemical treatments

International Nuclear Information System (INIS)

Al-Masri, M.R.

2001-08-01

Experiments were carried out to study the changes in the values of in-vitro apparent organic matter digestibility (IVOMD), metabolizable energy (ME) and net energy lactation (NEL) of wheat straw, sunflower seed shell, olive cake wood, date palm seeds and peanut shell after spraying with different concentrations of hydrobromic acid (HBr) and sodium hydroxide (NaOH) (0,3,6 ml HBr and 3,6 g NaOH/25 ml water/100 g DM) or after exposure to various doses of gamma radiation (0, 20, 40, 60 kGy). Results indicated that, except for the date palm seeds, the chemical treatments with either HBr or NaOH significantly (P<0.05) increased IVOMD, Me and NEL values for all treated samples. The experimental agricultural wastes did not respond equally to the chemical treatments investigated, i.e. they differ in the induced increases pertaining to their IVOMD, ME and NEL. The highest changes in the studied parameters due to chemical treatments were obtained when applying the 6% concentration. There was no significant effect (P<0.05) of irradiation on IVOMD, ME and NEL values for all treated samples. Moreover, the combined treatments of irradiation and hydrobromic acid or sodium hydroxide were found to have no significant affects on the IVOMD, ME and NEL values compared to the individual chemical treatments.

POLISH FARM MACHINERY MARKET AFTER ACCESSION TO THE EUROPEAN UNION – PRODUCTION AND SUPPLY OF MEANS OF AGRICULTURAL MECHANIZATION

Directory of Open Access Journals (Sweden)

Jan Pawlak

2014-09-01

Full Text Available After accession to the EU in 2004 the demand for tractors and agricultural implements has grown, followed by increasing supply of them. In 2012, the supply of brand-new agricultural tractors was by 185.4% higher than in 2003. In 2012 the value of renovation index of tractor fleet in agriculture was by 149.3% higher than in 2003. In spite of significant increase of demand for tractors, their production in 2012 was by 39.2% lower than in 2003. The downfall in number of tractors produced in Poland caused that imported tractors achieved more and more important share in supplies on Polish market. In 2003 the share of imports amounted to 64.0% and in 2012 – 91.4%. Production of most other means of agricultural mechanization was in 2012 higher than in 2003. The increase in a case of manure spreaders amounted to 704.3%; self loading or unloading agricultural tractor trailers – 362.1%; fertilizer spreader – 335.2%; field sowing machines – 245.3%; pick-up balers – 222.1% and harvester threshers – 194.8. Decreases were noted in cases of steamers – by 73.3%; potato planters – by 49.7%; harrows other than disc ones – by 42.2%; potato diggers – by 31.2% and rototillers – by 22.8%.

Sustainability and Competitiveness of Romanian Farms through Organic Agriculture

Directory of Open Access Journals (Sweden)

Mirela Ionela Aceleanu

2016-03-01

Full Text Available Currently, the development of any sector involves respecting the principles of sustainability, which means economic, social and environmental development. Moreover, organic farming is a very important field for ensuring sustainable development. Romania has great potential for the development of organic agriculture, especially due to the large number of available farmland and reduced use of fertilizers and other chemicals. However, the development of organic farming in Romania is in an early stage, due to the numerous problems that Romanian agriculture is still facing. Concern for the environment should be reflected at the level of production processes and consumption. As market demand influences and stimulates production, we can ask the question to what extent stimulating the consumption of organic products through green marketing can boost organic agriculture development and competitiveness of Romanian farms. Using several methods of research, such as analysis, synthesis, comparison, statistical methods and by calling on studies, reports and data series on organic farming in the EU and Romania, this paper highlights Romania's position in terms of the level of development of organic agriculture and recommends several ways to improve the outcomes obtained by Romania in the field. Moreover, based on regression equations, the trend of convergence of Romanian organic agriculture development in relation to the EU countries is analysed. The paper demonstrates that one of the measures that can be taken by Romanian farms is green marketing strategy development that can stimulate both consumption and production of organic products. Therefore, with increasing interest in the development of organic agriculture in Romania, green marketing can play an increasingly important role in promoting the benefits of consuming organic products, thus contributing to business development of organic products as well as to the development of Romanian agriculture

Culture clash: alcohol marketing and public health aspirations.

Science.gov (United States)

Munro, Geoffrey; de Wever, Johanna

2008-03-01

It is of no coincidence that a number of recent Harm Reduction Digests have addressed the issue of the reduction of alcohol-related harm. Despite the dominant focus on illicit drug use in the popular discourse, alcohol remains Australia's number one drug problem, as it is in many other developed countries. In this Digest Munro and de Wever use the 'four Ps' of marketing: product, price, place and promotion, to critique the two decades industry self-regulation of alcohol marketing. They conclude that if we are going to develop policies which effectively change Australian drinking culture to reduce alcohol-related harm, we need first to accept that the alcohol industry and the health field have separate and conflicting interests.

Hannu E.S. Haapala

2013-09-01

Full Text Available An OECD funded research was conducted where methods and processes for speeding up innovation in agriculture were assessed. A global web-based questionnaire was sent to experts in agricultural engineering, research, marketing, education and users of new technologies. Interviews of selected experts were done to deepen the analysis. The results show that considerable part of the relatively slow innovation comes from the fact that users do not trust in new technologies or that the usability of them is unacceptable. The experts suggest that education of the engineers and designers should include more elements from User-Centered Design (UCD and also User-Driven Innovation methods should be more used. As a conclusion a new ‘Dream Team’ of agricultural innovation was developed where user interaction and marketing professionals were given more roles.

Marketing Green Fertilizers: Insights into Consumer Preferences

Directory of Open Access Journals (Sweden)

Johannes Dahlin

2016-11-01

Full Text Available In an effort to support the long-term viability of the bioenergy industry through an end market for digestate, we investigated purchasing preferences for fertilizer product features in the home gardening market. We conducted a discrete choice experiment (DCE, presenting 504 respondents with a total of 6048 product attribute choices in a simulated context that replicated the tradeoff decisions made in the real marketplace. We analyzed the choice data using a hierarchical Bayes estimate to generate part-worth utilities for fertilizer product attributes. We then conducted a latent class analysis to identify market segments that could be expected to respond to differentiated product design strategies. We were able to quantify both purchasing preferences for fertilizer product attributes as well as the importance of each attribute to the perceived utility of a product. We were further able to identify five distinct market segments that make clear the potential for differentiated strategies in the home gardening market. We found both negative and positive price sensitivities, with sociodemographically distinct subgroups that favored low-, mid-, and high-priced products. We also found purchasing preferences for brand status, product labeling and nutrient values. Our results provide insights that should help product managers in the biogas industry develop marketing strategies to integrate digestate into a sustainable energy production system.

In this study biogas and high quality digestate were recovered from winery waste (wine lees) through anaerobic co-digestion with waste activated sludge both in mesophilic and thermophilic conditions. The two conditions studied showed similar yields (0.40 m(3)/kgCODfed) but different biological process stability: in fact the mesophilic process was clearly more stable than the thermophilic one in terms of bioprocess parameters. The resulting digestates showed good characteristics for both the tested conditions: heavy metals, dioxins (PCDD/F), and dioxin like bi-phenyls (PCBs) were concentred in the effluent if compared with the influent because of the important reduction of the solid dry matter, but remained at levels acceptable for agricultural reuse. Pathogens in digestate decreased. Best reductions were observed in thermophilic condition, while at 37°C the concentration of Escherichia coli was at concentrations level as high as 1000 UFC/g. Dewatering properties of digestates were evaluated by means of the capillary suction time (CST) and specific resistance to filtration (SRF) tests and it was found that a good dewatering level was achievable only when high doses of polymer (more than 25 g per kg dry solids) were added to sludge.

In the present study, three full-scale biogas plants (BGP) were investigated for the concentration of heavy metals, organic pollutants, pesticides and the pathogenic bacteria Bacillus cereus and Escherichia coli in the anaerobically digested residues (ADR). The BGPs mainly utilize source-separated organic wastes and industrial food waste as energy sources and separate the ADR into an ADR-liquid and an ADR-solid fraction by centrifugation at the BGP. According to the Norwegian standard for organic fertilizers, the ADR were classified as quality 1 mainly because of high zinc (132-422 mg kg -1 DM) and copper (23-93 mg kg -1 DM) concentrations, but also because of high cadmium (0.21-0.60 mg kg -1 DM) concentrations in the liquid-ADR. In the screening of organic pollutants, only DEHP (9.7-62.1 mg kg -1 ) and Σ PAH 16 (0.2-1.98 mg kg -1 DM) were detected in high concentrations according to international regulations. Of the 250 pesticides analyzed, 11 were detected, but only imazalil ( -1 DM) and thiabendazol ( -1 DM) were frequently detected in the ADR-fiber. Concentrations of imazalil and thiabendazol were highest during the winter months, due to a high consumption of citrus fruits in Norway in this period. Ten percent of the ADR-liquid samples contained cereulide-producing B. cereus, whereas no verotoxigenic E. coli was detected. The authors conclude that the risk of chemical and bacterial contamination of the food chain or the environment from agricultural use of ADR seems low.

Daniela Konstantinovna Sanakoeva

2015-12-01

Full Text Available The article reviews primary directions for economical regulation of agriculture, for solving problems of insufficient funds of agricultural enterprises. Goals for development of agricultural economics growth and competitive abilities are determined, economical measures for governmental support are described as functions of system for development of agricultural market. The authors reveal the problems of innovational and optimizational model for development of agriculture, and system of state regulative and supportive measures for implementing the innovational model of development by consolidation of self-development mechanisms within revealing of inner economical reserves and activisation of “growth points” for resource potential. The mutual system dependence for mechanisms of taxes and subsidiaries and their influence on budget and socio-economical externalities are analyzed. It is substantiated that the state regulation of agricultural markets must take into account low incomes of small agricultural business, not allowing to accumulate necessary funds for starting cooperation. Due to that, the article specially reviews issues of loan availableness for small agricultural enterprises, including private farmings, peasant farms and cooperatives created by them, and, for this goal, the issues of marketing effectiveness for production of such small forms of agriculture are further reviewed. As a result of research, the authors discovered the necessity for government support of socially important businesses in agriculture, which are not of high profitability and, due to that, are not attractive for investors, but are necessary for saving the traditional rural lifestyle and maintaining important social functions for sustainable development.

Anaerobic digestion of paunch in a CSTR for renewable energy production and nutrient mineralization.

Nkemka, Valentine Nkongndem; Marchbank, Douglas H; Hao, Xiying

2015-09-01

A laboratory study investigated the anaerobic digestion of paunch in a continuous stirred tank reactor (CSTR) for the recovery of biogas and mineralization of nutrients. At an organic loading rate (OLR) of 2.8gVSL(-1)day(-1) with a 30-day hydraulic retention time (HRT), a CH4 yield of 0.213Lg(-1)VS and CH4 production rate of 0.600LL(-1)day(-1) were obtained. Post-anaerobic digestion of the effluent from the CSTR for 30days at 40°C recovered 0.067Lg(-1)VS as CH4, which was 21% of the batch CH4 potential. Post-digestion of the effluent from the digestate obtained at this OLR is needed to meet the stable effluent criteria. Furthermore, low levels of soluble ions such as K(+), Ca(2+) and Mg(2+) were found in the liquid fraction of the digestate and the remainder could have been retained in the solid digestate fraction. This study demonstrates the potential of biogas production from paunch in providing renewable energy. In addition, recovery of plant nutrients in the digestate is important for a sustainable agricultural system. Crown Copyright © 2015. Published by Elsevier Ltd. All rights reserved.

Anaerobic co-digestion of dairy manure and potato waste

Science.gov (United States)

Yadanaparthi, Sai Krishna Reddy

Dairy and potato are two important agricultural commodities in Idaho. Both the dairy and potato processing industries produce a huge amount of waste which could cause environmental pollution. To minimize the impact of potential pollution associated with dairy manure (DM) and potato waste (PW), anaerobic co-digestion has been considered as one of the best treatment process. The purpose of this research is to evaluate the anaerobic co-digestion of dairy manure and potato waste in terms of process stability, biogas generation, construction and operating costs, and potential revenue. For this purpose, I conducted 1) a literature review, 2) a lab study on anaerobic co-digestion of dairy manure and potato waste at three different temperature ranges (ambient (20-25°C), mesophilic (35-37°C) and thermophilic (55-57°C) with five mixing ratios (DM:PW-100:0, 90:10, 80:20, 60:40, 40:60), and 3) a financial analysis for anaerobic digesters based on assumed different capital costs and the results from the lab co-digestion study. The literature review indicates that several types of organic waste were co-digested with DM. Dairy manure is a suitable base matter for the co-digestion process in terms of digestion process stability and methane (CH4) production (Chapter 2). The lab tests showed that co-digestion of DM with PW was better than digestion of DM alone in terms of biogas and CH4 productions (Chapter 3). The financial analysis reveals DM and PW can be used as substrate for full size anaerobic digesters to generate positive cash flow within a ten year time period. Based on this research, the following conclusions and recommendations were made: ▸ The ratio of DM:PW-80:20 is recommended at thermophilic temperatures and the ratio of DM:PW-90:10 was recommended at mesophilic temperatures for optimum biogas and CH4 productions. ▸ In cases of anaerobic digesters operated with electricity generation equipment (generators), low cost plug flow digesters (capital cost of 600/cow

Decentralized biogas technology of anaerobic digestion and farm ecosystem: opportunities and challenges

Directory of Open Access Journals (Sweden)

Junye eWang

2014-03-01

Full Text Available Long-term economic and environmental concerns have resulted in a great amount of research on renewable sources of biomass and bioenergy to replace fossil fuels in the past decades. Decentralized biogas technology is one of the most potential technologies of biomass and bioenergy by using agricultural waste materials (e.g., animal manure, crop straw and by-products from food industries as feedstocks. By-products from biogas production, called digestate, are nutrient rich which could potentially be reused as green fertilizers in agriculture, thereby providing a sustainable substitute for synthetic fertilizers for ecosystem farm. Thus, the biogas production of anaerobic digestion (AD is win-win option for livestock and crop producers to address issues of waste management and energy supply, and to avoid contamination of surface and ground waters and emissions of odors and greenhouse gases. In this paper, we review biogas production technology and then evaluate environmental effects of digestate used as fertilizer. Finally, we discuss issues of deployment of decentralized biogas technology for ecosystem farms. Economic and technological barriers still exist for large scale deployment of biogas technology. Two national scale deployments in China and Nepal showed that the operational status of biogas digesters is not optimal and up to 50% of plants are non-functional after a short operation period regardless of the social and economic factors. Main barriers are a wide variation of feedstocks and environmental conditions (e.g., temperature over space and time. It becomes clear that the experimental conditions of the pilot plants need to be adjusted and calibrated to the local feedstocks and climate. Also, more research needs to be done in cold fermentation technology.

streams investigated were diverse and included food waste, cheese whey processing waste, brewery waste, FOG, poultry waste, beef and sheep abattoir waste and vegetable market waste. The preliminary findings of the YVW study showed favourable economic analysis and resulted in YVW inviting tenders for assistance in design, construction and operation of the waste to energy facility in July 2012. The higher level of accuracy achieved through the tendering process will provide more certainty to the business case, and the waste to energy facility will be built subject to business case verification. The facility is proposed to be co-located with a wastewater treatment plant. CWW is currently reviewing the concept design report for a Resource Recovery Centre (RCC) to consider the benefits sustainable organic waste management may deliver to its customers and community by beneficial reuse of water, energy and solids and the barriers that need to be overcome. The most commonly used technologies for digestion are mesophilic anaerobic digestion (MAD), thermophilic anaerobic digestion (TAD), temperature phased anaerobic digestion (TPAD) and acid-gas (AG) phased anaerobic digestion. The high temperature processes (TAD and TPAD) are not well suited for small facilities, and though MAD is well suited to small facilities it typically has medium process stability and potential for high strength waste to breakthrough. The acid-gas phased digestion is an appropriate process, which is more stable due to separate digesters for acidification and methane production, has lower risk of process failure, has comparable capital and operating cost, and a smaller footprint when compared to the other available technologies. Though the acid-gas phased digestion has advantages over other processes, the selected technology largely depends on the method of procurement (design-build-operate, design and construct, build-own-operate-transfer etc) and on the experience of involved parties with the various

Manure management is a major concern for dairy farms, as manure emits significant quantities of greenhouse gases and contains concentrated nutrients, especially nitrogen and phosphorus. Current manure management practices consist of spreading minimally processed manure on agricultural fields, which releases greenhouse gases directly to the atmosphere and often leads to nutrient overloading on fields and runoff to surface and groundwater. A novel manure treatment system has been proposed that mitigates many of the current environmental concerns and creates value added products from the manure including bioplastics, electricity, fertilizer, and animal bedding. DAIRIEES, an Excel based model, allows users to enter characteristics about a dairy farm’s manure, manure management plan, and regional market. Based on these inputs, the five main processes of the integrated system—fermenter, anaerobic digester, bioplastics reactor, algae cultivation, and hydrothermal liquefaction or fast pyrolysis system—are analyzed in detail using data from laboratory scale experiments supplemented by information on full-scale processes from the literature. The model can be used to estimate performance of the integrated manure treatment system, including: 1) carbon and nutrient sequestration, 2) quantities and market value of end products, and 3) the system’s overall economic viability. The DAIRIEES model outlines the major economic considerations for construction and operation of a full scale integrated treatment system. This information can be used to inform a more detailed pro forma analysis of the deployed system.
