Última NY Pollution Discharge Elimination Permits for CAFOs, Management Adjustments and the Environment AgEcon Enahoro, Dolapo K.; Schmit, Todd M.; Boisvert, Richard N.. Weakening demand for livestock and dairy produce, historically high prices for feed ingredients and increasingly strict regulations on animal waste management continue to put significant pressure on livestock and dairy operating margins. In this paper, we use representative farm mathematical programming models to analyze important linkages between farm management adjustments and changes in farm income due to recent changes in relevant agricultural prices and restrictions on land application of nutrients. We account explicitly for new restrictions on land application of nitrogen and phosphorus, and specifically applied to confined animal feeding operations (CAFOs). Our mathematical methods and the distinctive data available allows for the assessment of...

Ano: 2010 URL: http://purl.umn.edu/61143 Incorporating Environmentally Compliant Manure Nutrient Disposal Costs into Least-Cost Livestock Ration Formulation AgEcon Hadrich, Joleen C.; Wolf, Christopher A.; Black, J. Roy; Harsh, Stephen B.. Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements. We incorporate nutrient disposal costs into a modified least-cost ration formulation model to arrive at a joint least-cost decision that minimizes the sum of feed and net nutrient disposal costs. The method is demonstrated with phosphorus disposal costs on a representative dairy farm. Herd size, land availability and proximity, crop rotation, and initial soil phosphorus content are shown to be important in determining phosphorus disposal costs.
