摘要：Nutrients are a major source of water quality impairment. This paper compares efficient use of nutrientsin a wholly owned animal-crop production system versus an integrator-operator animal-crop productionsystem and highlights the operator's tradeoff between prevention and utilization of excreted nutrientsunder conditions of uncertainty. Results derived from the comparison of different production systems areused to infer the consequences of implementation of nutrient land application restrictions, a key elementin the recently drafted United States Department of Agriculture and United States EnvironmentalProtection Agency Unified Strategy for Animal Feeding Operations.
