"No-till" practices are used on over half of major cropland acres
Soil health improves when farmers refrain from disturbing the soil. While no-till production systems are increasingly used on land in corn, soybeans, and wheat?the three largest U.S. crops by acreage?they are not necessarily used every year. Field-level data, collected through the Agricultural Resource Management Survey, show that famers often rotate no-till with other tillage systems. Farmers growing wheat (in 2009), corn (in 2010), and soybeans (in 2012) were asked about no-till use in the survey year and the 3 previous years.
