Corn Residue

Figure 1. Where moisture is not limited, research shows that removing some corn residue from a field may benefit yield in the following crop. However, if residue is removed for more than three years, research showed longer term impacts to the soil.

Crop Residue Removal: Impacts on Yield December 8, 2017

A review of multiple research studies indicates that where moisture is not limited, residue removal can result in no yield reduction to yield increases for the subsequent crop. However, long-term residue removal has been shown to affect other production factors and it's recommended that even in minimal erosion areas, removing residue does impact other production factors and it's recommended that 2.4 tons/acre of residue be left in the field.
