Tillage Practices Vary Across the United States
USDA ERS - Washington, D.C. No-till and strip-till are two of many tillage methods farmers use to plant crops. In a no-till system, farmers plant directly into the undisturbed residue of the previous crop without tillage, except for nutrient injection; in a strip-till system, only a narrow strip is tilled where row crops are planted. These tillage practices contribute to improving soil health, and reduce net greenhouse gas emissions. During 2010-11, about 23 percent of land in corn, cotton, soybeans, and wheat was on a farm where no-till/strip-till was used on every acre (full adopters). Another 33 percent of acreage in these crops was located on farms where a mix of no-till, strip-till, and other tillage practices were used on only some acres (partial adopters). In the Prairie Gateway, Northern Great Plains, and Heartland regions—which account for 72 percent of corn, soybean, wheat, and cotton acreage—more than half of these crop acres were on farms that used no-till/strip-till to some extent. Partial adopters have the equipment and expertise, at least for some crops, to use no-till/strip-till; these farmers may be well positioned to expand these practices to a larger share of cropland acreage.
