Goals of sustainable agriculture include reduced soil erosion, maintenance and restoration of crop productivity, reduced pollution of ground and surface water, and farm profitability. A major means of accomplishing these goals is the wide-spread adoption of conservation tillage, in which significant levels of crop residue remain on the soil surface to reduce soil erosion. Complementary to the erosion control goals of sustainable agriculture are the conservation compliance provisions of the Illinois T by 2000 program, the U.S. Food Security Act of 1985, and the 1990 Farm bill. These federal and state acts require conservation measures be used on land classified as highly erodible. A major conservation measure to be used to meet compliance is conservation tillage. New computer programs compare alternative farming methods on the basis of costs of machinery, herbicides, fertilizers, and other crop inputs that aid in the farm sector's decision making. One Illinois computer program was designed to assist in selecting a low cost set of machinery for a farm. It schedules the desired field operations and calculates all machinery related costs. Computer programs and economic budgeting worksheets provide efficient methods for determining profitability of different tillage systems.
