| This analysis determines profit maximizing N fertilization levels of hard red spring wheat (HRSW) for various wheat prices, N prices, and protein-based HRSW price premium/discount (P/D) structures for south eastern Washington data. Fertilizer response data consisting of rates of N fertilization (lb/ac), grain yield (bu/ac), and grain protein (%) were used to statistically estimate regression relationships that predicted yield and protein in response to N. All predicted net return maximizing N, protein, and yield levels were within the data range. Increasing P/D incentives for protein increased optimal N, the expected economic result. At the high P/D structures, the P/D structure dominated N and wheat prices in determining optimal N application levels.... |

| This study examines the question of income adequacy as it relates to the broader issue of an economically viable farm size in the Columbia Basin of Washington State. The issue is especially relevant because of possible limitations on farm size resulting from enforcement of the 1902 Reclamation Act. Income estimates derived under two alternative accounting frameworks - the standard economic accounting method and the after-tax cash flow accounting method - were examined. Findings were that the after tax cash flow accounting framework was more appropriate for examining the income adequacy aspect of the viability issue as it incorporated the effect of federal income taxes and farmer's equity, both of which are important determinates of income levels. Using the... |

| This study analyses short and long term safety first business risk associated with twenty six no-till transition strategies across four types of farms in eastern Washington. Risk of transition failure generated from risk averse criteria are also contrasted with a risk neutral criterion. Results revealed (1) that speeds of adoption have a larger effect than drill acquisition sequences in successful transition, (2) high equity farm have higher chance of success, and (3) slow acreage expansion with a custom or rental drill is preferred until yield penalty is eliminated. |

| Feedforward networks have powerful approximation capabilities without the "explosion of parameters" problem faced by Fourier and polynomial expansions. This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks. First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments. Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility. Third, we show how one can constrain feedforward networks to satisfy a priori information without losing their flexible... |

| Farm level risk analyses have used price and yield variability almost exclusively to represent risk. Results from a survey of 149 agricultural producers in 12 states indicate that producers consider a broader range of sources of variability in their operations. Significant differences exist among categories with respect to the importance of the sources of variability in crop and livestock production. Producers also used a variety of management responses to variability. There were significant difference among categories in the importance given to particular responses and their use of them. These results have implications for research, extension, and policy programs. |

| Logit and ordered probit analyses were used to identify factors associated with reduced tillage adoption, continuous spring cropping, and the number of changes made in response to wind erosion. Contrary to previous results for water erosion control, simple perception of a wind erosion problem or membership in a particular socioeconomic category did not significantly explain adoption of wind erosion control practices, but participating in a targeted educational program did. This educational program: (a) highlighted the threats of wind erosion to human health and to soil productivity, and (b) described specific potentially profitable farming practices for solving the wind erosion problem. |

| Crop yields, farm income risk and returns, and soil losses were simulated from 1974 to 1984 for southeastern Washington Palouse-region farms in three climatic subregions under alternative conservation and commodity policy scenarios. Historical commodity programs reinforced preexisting disincentives to retire highly erodible land to perennial grasses, but cropland base protection (CBP) legislation would eliminate such disincentives and increase profitability and decrease risk of land retirement. Nevertheless, additional incentives would be needed. Government rental payments can provide necessary incentives, but they are more costly without CBP. CBP was not included in the 1985 farm bill. |

| The Canadian prairies traditionally have been dominated by spring wheat production. Crop diversification is now being advocated to enhance farm-level risk management, ecological benefits, nutrient cycling, and pest and disease control, and to reduce the farm economy’s reliance on income from a single crop. There has always been interest in diversifying away from wheat, but until recently, economically feasible alternatives have been limited, and government policies may have constrained the shift to other crops. Knowing the impact of prices and policies on crop diversification is essential to understanding producer response and to determining strategies to enhance cropping diversity. |

| The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen the long run payoff to conservation tillage. Nonetheless, conservation tillage was found to be competitive with conventional tillage only if its current yield disadvantages were eliminated. Conservation tillage was relatively more competitive on shallower topsoils and for longer planning horizons. Short-term subsidies coupled with research directed towards reducing the cost and yield disadvantages of conservation tillage in the Palouse were advocated to maintain long-term soil productivity. |
