Última The Choice of Tillage, Rotation, and Soil Testing Practices: Economic and Environmental Implications AgEcon Wu, JunJie; Babcock, Bruce A.; Lakshminarayan, P.G.. Which management practices farmers adopt has a significant effect on agricultural pollution. Research has analyzed factors influencing adoption of a single management practice. But often adoption decisions about many practices are made simultaneously, which suggests use of a polychotomous-choice model to analyze decisions. We apply such a model to the choice of alternative management practices on cropland in the Central Nebraska Basin and control for self-selection and the interaction among alternative practices. We use the results of the choice model to estimate the economic and environmental effect so adopting alternative combinations of management practices. Our results suggest that crop rotation and soil N testing are complementary practices, perhaps...
