英文文献摘要：
Crop yields, farm income, and soil losses were simulated over 1974-84 for southeastern Washington farms in three climatic subregions under alternative conservation and commodity policy scenarios. Historical commodity programs reinforced disincentives to retire highly erodible land, but Cropland Base Protection legislation would increase profitability and decrease risk of land retirement.
