The management practices farmers choose have significant effect on agricultural pollution. The authors analyze the adoption of alternative combinations of conservation practices and their impacts on fertilizer use, corn yield, and soil erosion in the Central Nebraska Basin, using a polychotomous-choice selectivity model. The results suggest that soil N testing and corn-legume rotation complement each other, but that the interaction between conservation tillage and rotation is more complicated.
