Conservation tillage is a method used to reduce soil erosion in croplands. In 1981, about 27.4% of harvested cropland in the US used conservation tillage. The effectiveness of conservation tillage in controlling soil erosion varies by region, with the Corn Belt showing promising results. In this region, one-third of cropland used conservation tillage, with 2.5% using no-till methods. The use of conservation tillage is gradually increasing, and farmers who adopt these practices are more likely to continue using them. The effectiveness of conservation tillage in reducing soil erosion depends on factors like slope, rainfall, and soil characteristics.
