Alternatives for Reducing Insecticides on Cotton and Corn: Economic and Environmental Impact - Supplement 2: Procedures Used in Setting Up the Agricultural Production Model

摘要

The procedures used in setting up the agricultural production model used in a study of alternatives for reducing insecticides on cotton and corn are described. The major analytical tool used is a spatial equilibrium model of U.S. agriculture. This is a linear programming model that minimizes the cost of producing and transporting corn, sorghum, wheat, oats, barley, rye, soybeans, and cotton given resource availability, technology, and commodity demands. The model can be divided into a supply segment, a nutrient transfer segment,
