Conservation tillage, the practice of growing crops in ways that leave maximum crop residue on the soil surface, may provide an answer to farmers needing to cut costs without reducing quality of yield and to environmentalists concerned about water quality and pollution caused in part by intensive cropland farming. Four years of demonstration projects in 31 counties in Indiana, Michigan and Ohio have helped farmers adapt less intensive tillage systems to farm businesses. Projects provided information on the economics of conservation tillage and its impact on the environment.
