A MICROCOMPUTER MODEL FOR IRRIGATION SYSTEM EVALUATION AgEcon
Williams, Jeffery R.; Buller, Orlan H.; Dvorak, Gary J.; Manges, Harry L..
ICEASE (Irrigation Cost Estimator and System Evaluator) is a microcomputer model designed and developed to meet the need for conducting economic evaluation of adjustments to irrigation systems and management techniques to improve the use of irrigated water. ICEASE can calculate the annual operating costs for irrigation systems and has five options that can be used to economically evaluate improvements in the pumping plant or the way the irrigation system is used for crop production.

A Risk Analysis of Converting CRP Acres to a Wheat-Sorghum-Fallow Rotation AgEcon
Williams, Jeffery R.; Llewelyn, Richard V.; Pendell, Dustin L.; Schlegel, Alan J.; Troy, Dumler.
This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region. This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums. Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy. Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP...

A Yield Sensitivity Analysis of Conventional and Alternative Whole-Farm Budgets for a Typical Northeast Kansas Farm AgEcon
Diebel, Penelope L.; Llewelyn, Richard V.; Williams, Jeffery R..
This analysis compares net returns of conventional and alternative agricultural cropping systems in northeast Kansas, with and without government commodity programs. The highest net return is consistently from the alternative system, wheat/clover-sorghum-soybeans. Sensitivity analysis reveals that the economic performances of the alternative systems are sensitive to yield penalties.

An Economic Analysis of Carbon Sequestration for Wheat and Grain Sorghum Production in Kansas AgEcon
Aller, Taryn D.; Williams, Jeffery R.; Nelson, Richard G.; Claassen, Mark M.; Rice, Charles W..
This study examined the economic potential with and without carbon credit payments of two crop and tillage systems in South Central Kansas that could reduce carbon dioxide emissions and sequester carbon in the soil. Experiment station cropping practices, yield data, and soil carbon data for continuously cropped wheat and grain sorghum produced with conventional tillage and no-tillage from1986 to 1995 were used to determine soil carbon changes and to develop enterprise budgets to determine expected net returns for a typical dryland farm in South Central Kansas. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual soil C gains than under conventional tillage. Carbon credit...

An Economic Analysis of the IFMPO AgEcon
Williams, Jeffery R.; Diebel, Penelope L..
The Integrated Farm Management Program Option (IFMPO) of the 1990 farm bill is designed to increase crop management flexibility and promote the use of resource-conserving crops. Economic analysis of this program indicates that, although the current format provides flexibility, it provides little economic incentive to adopt resource-conserving crop rotations.

An Economic Comparison of Composted Manure and Commercial Nitrogen with Imperfect Information AgEcon
Berends, Patrick T.; Diebel, Penelope L.; Williams, Jeffery R.; Schlegel, Alan J..
The economic feasibility of fertilizing irrigated grain sorghum with compos ted manure is evaluated using net return budgeting and production function analysis. Although the use of compost is technically feasible, the economic analysis indicates that compost does not comprise a large percentage of the nitrogen source in the profit-maximizing combination with commercial fertilizer.

DERIVED CARBON CREDIT VALUES FOR CARBON SEQUESTRATION: DO CO2 EMISSIONS FROM PRODUCTION INPUTS MATTER ? AgEcon
Williams, Jeffery R.; Nelson, Richard G.; Aller, Taryn D.; Claassen, Mark M.; Rice, Charles W..
An economic analysis was conducted involving wheat and grain sorghum production systems that affect carbon dioxide emissions and sequester soil carbon. Parameters examined were expected net returns, changes in net carbon sequestered and the value of carbon credits necessary to equate net returns from systems that sequester more carbon to those that sequester less with and without adjustments for CO2 emissions from production inputs. Evaluations were based on experiment station cropping practices, yield, and soil carbon data for continuously cropped and rotated wheat and grain sorghum produced with conventional and no-tillage. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual...

EFFECTIVE LEARNING IN LARGE CLASSES THROUGH RISK MANAGEMENT AgEcon
Broder, Josef M.; Tew, Bernard V.; Williams, Jeffery R..
Risk management strategies for maintaining student performance in large classes are discussed. Risk management theory is discussed and used to describe student behavior. Results of risk management experiments in which students are exposed to alternative levels of grading are reported along with other factors which influence student behavior. Class performance was not found to decline under a system involving only a 50 percent chance of assignments being graded. Procedures for implementing and limitations of chance grading systems in large classes are discussed.

FARM CHARACTERISTICS THAT INFLUENCE NET FARM INCOME VARIABILITY AND LOSSES AgEcon
Dunn, Jerry W.; Williams, Jeffery R..
Farm-level, cross-section and panel data were used with econometric methods to examine relationships between variability in net farm income and explanatory variables including government payments, gross crop income, gross livestock income, costs, efficiency measures, and other socioeconomic characteristics such as age, leverage, percent of land rented, and enterprise diversification. The results suggest that quantifying the impacts of socioeconomic factors on variability of net farm income is difficult. Among the income variables, changes in gross crop income had the largest impact. Among cross-section data, increases in interest costs, age, and diversification were found to have positive relationships with net income variability. However, only the...

FARM VALUE OF TOPSOIL IN SPRING WHEAT PRODUCTION AgEcon
Williams, Jeffery R.; Tanaka, Donald L.; Herbel, Kevin L..
Relationships among topsoil removal treatments and additions of nitrogen and phosphorus fertilizer in spring wheat yields are used to determine the effects on net returns and to estimate the marginal value of soil. The results indicate that risk-averse managers are not willing to make an expenditure for controlling erosion from the first 2.5 inches of soil if the erosion rate is 20 tons/acre/year or less and the planning horizon is 20 years or less. These managers would be willing to make an erosion control investment for the second 2.5 inches of soil equivalent to $4.90 to $5.20/acre from the twenty-first to forty-third year in the planning horizon.

Farmers’ Willingness to Grow Sweet Sorghum as a Cellulosic Bioenergy Crop: A Stated Choice Approach AgEcon
Bergtold, Jason S.; Fewell, Jason E.; Williams, Jeffery R..
Biofuel production must increase to 36 billion gallons by the year 2022, according to government mandates. The majority of this fuel must be produced from “advanced” or second-generation biofuel feedstocks after 2015. Advanced biofuel feedstocks include annual crops such as sweet sorghum. Kansas farmers are poised to be major producers of sweet sorghum for biofuels. A stated choice survey was administered to Kansas farmers to assess their willingness to grow sweet sorghum for biofuels under various contracting scenarios. Results show that farmers are willing to grow biomass for bioenergy under contract and that insurance availability plays an important role in their decision.

Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop: A Stated Choice Approach AgEcon
Fewell, Jason E.; Bergtold, Jason S.; Williams, Jeffery R..
Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop: A Stated Choice Approach Agriculture’s role as a source of feedstocks in a potential lignocellulosic-based biofuel industry is a critical economic issue. Several studies have assessed the technical feasibility of producing bioenergy crops on agricultural lands. However, few of these studies have assessed farmers’ willingness to produce or supply bioenergy crops or crop residues. Biomass markets for bioenergy crops do not exist, and developing these markets may take several years. Therefore, an important, yet unaddressed question is under what contractual or pricing arrangements farmers will grow biomass for bioenergy in these nascent markets. The purpose of this paper is to examine...

MATHEMATICAL FORMULAS FOR CALCULATING NET RETURNS FROM PARTICIPATION IN GOVERNMENT PROGRAMS, CRP, AND CROP INSURANCE ALTERNATIVES AgEcon
Pendell, Dustin L.; Perry, William R.; Williams, Jeffery R.; Barnaby, Glenn Arthur, Jr.; Lubben, Bradley D..
The purpose of this report is to provide a revised version of the publication, "Mathematical Formulas for Calculating Net Returns from Participation in Government Commodity Programs including Marketing Loans" (Williams and Barnaby, 1994). The change in design of the government commodity programs and development of several crop insurance alternatives has been significant since the previous paper was published. The formulas for calculating net returns incorporate provisions from the Farm Security and Rural Investment Act of 2002 and several crop insurance designs developed in the 1990s. Individuals conducting research or education programs will be able to use this revision for reference when estimating net returns for producers under current commodity...

Net Returns for Grain Sorghum and Corn under Alternative Irrigation Systems in Western Kansas AgEcon
Williams, Jeffery R.; Llewelyn, Richard V.; Reed, Matthew S.; Lamm, Freddie R.; DeLano, Daniel R..
This study evaluates seven irrigation systems for use in production of grain sorghum and corn. These systems are medium pressure center-pivot (MPCP), low pressure center-pivot (LPCP), low drift nozzle center-pivot (LDN) , low energy precision application center-pivot (LEPA), furrow flood (FF) , surge flood (SF), and subsurface drip (SD). After-tax net present value estimates from investing in and using each system over a 10-year period to produce grain sorghum and corn are compared. The surge flood system, has the highest net returns under typical conditions for irrigation of both grain sorghum and corn. The furrow flood system generates the next highest net returns for both crops, followed by the subsurface drip system. The medium pressure center-pivot...
