Reducing tillage and increasing soil cover (through crop rotations and cover crops) can enhance soil health. To gauge the intensity of tillage over time, this report estimates the number of years no-till or strip-till are used over a 4-year period. Conservation tillage was used on 70 percent of soybean (2012), 65 percent of corn (2016), and 67 percent of wheat (2017) acres.
