| Regulatory changes by federal and state agencies portend a switch from nitrogen-based livestock manure disposal policies to phosphorus-based policies. This paper estimates the compliance costs of such a policy change for a hypothetical hog-grain farm in North Central Indiana. The farm includes 1,500 acres of cropland and has the capacity to raise 11,970 grow-finish hogs annually. The farm model also as the potential to produce four different crops on six different land types. A nonlinear math-programming model was developed to determine the optimal mix of management activities for a phosphorus-based regulation. The model allows mitigation of compliance costs via the choice between four different pig diets, three alternative methods of manure disposal,... |

| Federal and State regulatory agencies are considering switching from a nitrogen-based manure disposal policy to one that is phosphorus-based. This analysis estimates the compliance costs of this policy change for a representative hog-grain farm in Wabash County, Indiana. The representative farm includes 1,500 acres of cropland and has the capacity to raise 11,970 grow-finish hogs annually. The farm model also has the potential to produce four different crops on six different land types. A non-linear math-programming model was developed for this study to determine the optimal mix of management activities for a phosphorus-based regulation. The model maximizes farm returns above variable costs, subject to resource and regulatory constraints. The model allows... |
