| 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,... |

| The U.S. agricultural production and food distribution industry is currently in the midst of major structural changes. To assist in understanding the implications of these changes and the future of the industry, faculty in the School of Agriculture at Purdue University in collaboration with industry representatives undertook a study to assess the future of the food production, processing and distribution system. The results of this analysis are reported in detail in "Food System 21: Gearing Up for the New Millennium". This publication is one chapter of that book. It discusses the future challenges and opportunities in the U.S. hog/pork sector and the type of industry that is expected to evolve. For a copy of the entire Food System 21 study, contact:... |
