Conservation Tillage

Any tillage and planting system that leaves at least 30% of the soil surface covered by residue after planting. Conservation tillage maintains a ground cover with less soil disturbance than traditional cultivation, thereby reducing soil loss and energy use while maintaining crop yields and quality. Conservation tillage techniques include minimum tillage, mulch tillage, ridge tillage, and no-till. Conservation tillage varies widely by crop and soil type, but more than 100 million acres is cropped using some form of conservation tillage, according to annual surveys conducted by the Conservation Technology Information Center.
