Farm-Level Effects of Soil Conservation and Commodity Policy Alternatives: Model and Data Documentation.
Sutton, John D.
This report documents a profit-maximizing linear programming (LP) model of a farm typical of a major corn-soybean producing area in the Southern Michigan-Northern Indiana Drift Plain. Following an introduction, a complete description of the farm is provided. The next section presents the LP model, which is structured to help analyze after-tax income and erosion effects of soil conservation and commodity program options on cash-grain farms having various land, labor, and financial resources. The model can be used directly or easily modified for farms in other critically eroding Major Land Resource Areas (MLRAs). (The model maximizes after-tax farm income subject to a simultaneous system of linear resource constraints.) The mathematical expression of the model is presented; a sample tableau of the LP matrix follows as well as a full documentation of the purpose and coefficient derivation procedure for each row and column. Symbols used in the equations appear immediately after the equations. Other contents include a description of the data sets used for this study and the output report of a sample optimization run on a microcomputer. (YLB)
