Iowa Crop Production and Soil Erosion with Cropland Expansion

Orley M. Amos and John F. Timmons

American Journal of Agricultural Economics, 1983, vol. 65, issue 3, 486-492

Abstract: A parametric programming model is used to estimate crop production profitability of Iowa's noncropland. The model indicates that Iowa cropland is expandable by five million acres if crop prices double the 1978 level. Additional cropland expansion is less responsive to further crop price increases. The model also indicates that soil erosion from cropland expansion is greater than the state's average. However, if the model constrains soil erosion to under five tons per acre, soil erosion is greatly reduced with only slight reductions in potential cropland.
