USDA ERS - No-Till or Strip-Till Use Varies by Region

No-till and strip-till are two of many tillage methods farmers use to plant crops. During 2010-11, roughly 56 percent of all U.S. land used for corn, cotton, soybeans, and wheat was located on farms that used no-till/strip-till on at least some portion of this cropland.
