A major component of the program is educational assistance provided through a statewide coordinator and five regional specialists working with conservation agencies, agribusinesses, agricultural and environmental organizations, and cooperating farmers. Generally, conservation tillage systems, which leave at least 30 percent of the soil surface covered by crop residue after planting, reduce sheet and rill erosion 50 percent compared to conventional tillage systems. Increasing the adoption of conservation tillage systems on Indiana's cropland will thus aid in achieving the T-by-2OOO program goal of significantly reducing soil erosion. Recent studies in the midwest (4, 5, 7), however, indicate that economic factors, including equipment purchases and perceived higher chemical control costs, are the major obstacle to conservation tillage adoption. Additionally, Indiana surveys reveal that less than 25 percent of cropland with slopes greater man 6 percent is treated with some form of conservation tillage (S). Given this current status of land treatment and the constraints to adoption of conservation tillage, the T … ER -
