Book excerpt: In agriculture, uncertainty permeates almost all types of decisions, a fact that greatly complicates the process by which choices are made. This study develops a method that combines fertilization-response data with preferences of decision makers, to help research and extension workers improve their fertilizer-application recommendations. To prescribe preferred fertilizer practices tailored to the risk preferences of individual decision makers, this study adopted two objectives: (1) to estimate risk aversion coefficients for corn farmers in the Cerrado region of Brazil and to relate them to socio-economic variables, and (2) to measure how farmers' attitudes toward risk influence their adoption of alternative corn-production techniques. To achieve the first objective, regression and discriminant analyses were employed to relate the measures of absolute risk-aversion coefficients, measured for 114 farmers in the Cerrado region, to selected socioeconomic variables, and to classify the farmers into different groups, based on their attitudes toward risk. The results showed that there seems to be a strong relationship between risk attitudes and socioeconomic variables such as age, educational level, family size, size of farm, income, and sources of information, and that different tenure arrangements may reveal different attitudes toward risk. A significant percentage of the individuals studied displayed risk preferences at least for the situation analyzed. To achieve the second objective, physical relationships, including the corn-response production function and the phosphorus carry-over fuction, were analyzed together with randomly generated weather patterns. A Monte Carlo program then was used to construct a large number of strategies that were evaluated by choice criterion stochastic dominance with respect to a function. This criterion provided sets of efficient choices for each class of decision makers. Model results indicated that the introduction of farmers' preferences in the form of risk-aversion measures has an important influence on decision-making choices. Highly risk-averse farmers, for example, tend to make use of strategies that produce, in general, lower expected returns and lower probability of losses. This indicates that one should recommend strategies efficiently tailored to each class of decision makers.

Available in PDF, EPUB and Kindle. Book excerpt: The results indicate that a grower would choose to continue with field-grown tomato production due to high option value and risk aversion. These results are consistent with what has been witnessed in tomato production in Florida. However, policies or market conditions such increase credit availability, increase interest rates, decrease energy prices, stabilize high tomato prices would make the greenhouse production more preferable. Finally, the third essay examines the production risk and the choices of fertilizer application rates by Florida potato producers. Nitrogen fertilizer is commonly used as a strategy to manage production risks; however, excessive nitrogen application has the potential to impact surface water quality. Using county-level data, the study explores the economically optimal nitrogen fertilizer rate by explicitly considering the production risks and producers\U+2019\ risk perceptions. The results show that no single fertilizer BMP can be recommended for all growers and all market conditions. Overall, the three essays contribute to the economic literature on agricultural risk management, and generate information to assist agricultural producers and policy makers.

Available in PDF, EPUB and Kindle. Book excerpt: Farmers apply fertilizers to crops in order to produce maximum economic return. To attain this, it is important that fertilizer requirements can be estimated accurately. The prevention of excessive use of fertilizers on economic grounds also has the beneficial consequence of minimizing environmental pollution of groundwaters through the leaching of unused fertilizers. This book is intended for both the agricultural scientist who is engaged in research on the use of fertilizers in crop production and consultants who might assist with the interpretation of statistical data. Relevant mathematical and statistical procedures are described critically, indicating their basis and limitations, and how they may be used or misused. Some basic knowledge of statistics is assumed on the part of the reader. Many of the procedures have been developed by the author from experience in soil fertility projects in Australia, Canada, the USA and a number of less-developed countries.

Book excerpt: "With ever-increasing pressures on world agriculture in both economic and environmental terms, application of the concept of precision agriculture is one way of enabling farmers and producers to cope. ‘Doing arable agriculture and horticulture more precisely’ means that the use of inputs is optimised, crop yield and quality are maximised and leakage of agro-chemicals and fertilisers to the environment is minimised. This publication contains papers presented at the 6th European Conference on Precision Agriculture. The papers reflect the wide range of disciplines encompassed by precision agriculture, including: soil physics, crop physiology, agronomy, IT, agricultural technology, sensor technology, remote sensing, geostatistics and environmental science. The wide range of research topics reported will be a valuable resource for researchers, advisors, teachers and professionals in agriculture long after the conference has finished. Peer-reviewed papers from the 3rd European Conference on Precision Livestock Farming are presented in a companion proceedings, Precision livestock farming ’07."

Download or read book Effects of Federal Risk Management Programs on Investment, Production, and Contract Design Under Uncertainty written by Sangtaek Seo and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural producers face uncertain agricultural production and market conditions. Much of the uncertainty faced by agricultural producers cannot be controlled by the producer, but can be managed. Several risk management programs are available in the U.S. to help manage uncertainties in agricultural production, marketing, and finance. This study focuses on the farm level economic implications of the federal risk management programs. In particular, the effects of the federal risk management programs on investment, production, and contract design are investigated. The dissertation is comprised of three essays. The unifying theme of these essays is the economic analysis of crop insurance programs. The first essay examines the effects of revenue insurance on the entry and exit thresholds of table grape producers using a real option approach. The results show that revenue insurance decreases the entry and exit thresholds compared with no revenue insurance, thus increasing the investment and current farming operation. If the policy goal is to induce more farmers in grape farming, the insurance policy with a high coverage level and high subsidy rate is effective. In the second essay, a mathematical programming model is used to examine the effects of federal risk management programs on optimal nitrogen fertilizer use and land allocation simultaneously. Current insurance programs and the Marketing Loan Program increase the optimal fertilizer rate 2% and increase the optimal cotton acreage119-130% in a Texas cotton-sorghum system. Assuming nitrogen is harmful to the environment and cotton requires higher nitrogen use, these risk management programs counteract federal environmental programs. The third essay uses a principal-agent model to examine the optimal contract design that induces the best effort from the farmer when crop insurance is purchased. With the introduction of crop insurance, the investor's optimal equity financing contract requires that the farmer bear more risk in order to have the incentive to work hard, which is achieved by increasing variable compensation and decreasing fixed compensation.

Available in PDF, EPUB and Kindle. Book excerpt: This Fertilizer Manual was prepared by the International Fertilizer Development Center (IFDC) as a joint project with the United Nations Industrial Development Organi zation (UNIDO). It is designed to replace the UN Fertilizer Manual published in 1967 and intended to be a reference source on fertilizer production technology and economics and fertilizer industry planning for developing countries. The aim of the new manual is to describe in clear, simple language all major fertilizer processes, their requirements, advan tages and disadvantages and to show illustrative examples of economic evaluations. The manual is organized in five parts. Part I deals with the history of fertilizers, world outlook, the role of fertilizers in agriculture, and raw materials and includes a glossary of fertilizer-related terms. Part II covers the production and transportation of ammonia and all important nitrogen fertilizers-liquids and solids. Part III deals with the characteristics of phosphate rock, production of sulfuric and phosphoric acid, and all important phosphate fertilizers, including nitrophosphates and ammonium phosphates. Part IV deals with potash fertilizers-ore mining and refining and chemical manufac ture; compound fertilizers; secondary and micronutrients; controlled-release fertilizers; and physical properties of fertilizers. Part V includes chapters on planning a fertilizer industry, pollution control, the economics of production of major fertilizer products anJ intermediates, and problems facing the world fertilizer industry.

Book excerpt: Soil fertility refers to the ability of a soil to supply plant nutrients. Bioavailable phosphorus is the element in soil that is most often lacking. Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example a 10-10-15 fertilizer has 10 percent nitrogen. Inorganic fertilizers are generally less expensive and have higher concentrations of nutrients than organic fertilizers. Also, since nitrogen, phosphorus and potassium generally must be in the inorganic forms to be taken up by plants, inorganic fertilizers are generally immediately bioavailable to plants without modification. However, some have criticized the use of inorganic fertilizers, claiming that the water-soluble nitrogen doesn't provide for the long-term needs of the plant and creates water pollution.
