THE CHOICE OF TILLAGE, ROTATION, AND SOIL TESTING PRACTICES - ECONOMIC AND ENVIRONMENTAL IMPLICATIONS

Farmers' management practices can have a significant effect on agricul tural pollution. Past research has analyzed factors influencing adopti on of a single management practice. But often adoption decisions about many practices are made simultaneously, which suggests use of a polyc hotomous-choice model to analyze decisions. Such a model is applied to the choice of alternative management practices on cropland in the Cen tral Nebraska Basin and controlled for self-selection and the interact ion between alternative practices. The results of the choice model are used to estimate the economic and environmental effects of adopting a lternative combinations of management practices.
