| Recent trends in livestock concentration suggest that there may be an increasing risk of water pollution from manure applications. These trends in livestock operations may be offsetting improvements in commercial fertilizer management that have the potential to reduce the risk of water pollution. This conclusion was derived by tracking excess nutrient trends between 1996 and 2002 and by examining measures of economic performance for livestock farms. First, a link was established between the expansion of AFOs (Animal Feeding Operations) and excess nutrients from commercial fertilizer and manure sources. Second, technical efficiency was measured in order to identify whether technical efficiency explains structural change and in order to see whether... |

| This research presents a competitive dynamic model to evaluate the economic and groundwater quality benefits resulting from the adoption of soil/water nitrogen testing. The model is applied to an irrigated corn production county in the Nebraska Mid-State area where the groundwater contamination level from nitrates is reported to be, on average, 18.7 parts per million (ppm). Adoption of nutrient management practices would result in increased economic benefits to farmers and reduced nitrate stocks in groundwater. |

| Recent trends in livestock concentration in major corn producing states suggest that increasing risk of water pollution from manure applications may be offsetting declines in risk of water pollution from chemical fertilizer. Analysis of data from ARMS surveys found that potential excess nitrogen and phosphorous per corn acre increases sharply between 1996 and 2001 when manure nutrient credits are included. Cohort analysis of farms found that the level of technical efficiency appears to be positively associated with potential nutrient pollution from both sources. Operations with high ratios of manure applied to manure produced and excess phosphorous tend to be more technically efficient than operations with low ratios of manure applied to manure produced... |

| U.S. dairy operations are sorted via a multinomial logit model into three production systems: pasture-based, semi-pasture-based, and conventional. Region, farm size, financial situation, and production intensity measures impact system choice. Analysis follows to determine the impact of production system on enterprise profitability. Region, farm size, and demographic variables impact profitability, as does system choice: semi-pasture-based operations were less profitable than conventional operations on an enterprise, per hundredweight of milk produced basis. Significant differences were not found in the profitability of pasture-based operations versus those using other systems. |

| U.S. dairy production is consolidating into fewer but larger farms. This report uses data from several USDA surveys to detail that consolidation and to analyze the financial drivers of consolidation. Specifically, larger farms realize lower production costs. Although small dairy farms realize higher revenue per hundredweight of milk sold, the cost advantages of larger size allow large farms to be profitable, on average, even while most small farms are unable to earn enough to replace their capital. Further survey evidence, as well as the financial data, suggest that consolidation is likely to continue. |

| This study identifies and analyzes factors that contribute to the success of small farms. Particular attention is given to the effect of participation in marketing and supply cooperatives on the success of small farms. Using modified net farm income per dollar of assets and operator’s labor and management income as measures of success, results show participation in marketing and supply cooperatives is positively correlated with success. Further, analysis findings indicate farm size, controlling for variable and fixed costs, type of ownership, management strategies used, working off the farm, and age of the operator are important factors that influence profitability (modified net farm income per dollar of assets and operator’s labor and management income)... |
