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. |

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. |

This study compares the effectiveness of five crop insurance/disaster assistance plans: an individual farm-yield insurance plan similar to the current Federal Crop Insurance Corporation multiperil program, two area-yield insurance plans, a farm-yield disaster assistance plan, and an area-yield disaster assistance plan. These methods are examined for reduction in yield and gross income variability with and without participation in the government deficiency payment program using farm-level yield data from 98 dryland wheat farms and 38 dryland corn farms in Kansas. Although individual farm-yield insurance is complex, suffers from moral hazard and adverse selection problems, and is likely to be the most expensive to administer, it provides more yield and gross... |

Farm-level, cross-section and panel data were used with econometric methods to examine relationships between variability in the rate of return to capital managed and explanatory variables including government payments per crop acre, gross crop income, gross livestock income, costs, efficiency measures, and other socioeconomic characteristics. Quantifying the impacts of socioeconomic factors on variability of the rate of return was difficult. Increasing the standard deviation of gross revenue and government payments increased the variability in rate of return to capital managed. An increase in the variability of labor, crop & equipment, livestock, and interest costs had the opposite effect. In addition, increase in labor and livestock costs to gross... |

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... |

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... |

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... |
