While residue prevents erosion and provides organic matter, it also holds moisture and prevents optimal drying and warming of the seedbed.
The Agriculture Department Economic Research Service recently released a report on tillage intensity and conservation cropping practices. Conservation tillage was used on a majority of wheat (67 percent), corn (65 percent), and soybeans (70 percent) acres.
Managing heavy corn residue can be challenging, but Iowa State University says tillage is not always the most effective or profitable solution.
