Pieces of crop residue shield soil particles from rain and wind until plants can produce a protective canopy. How it helps Ground cover prevents soil erosion and protects water quality. Residue improves soil tilth and adds organic matter to the soil as it decomposes. Fewer trips and less tillage reduces soil compaction. Time, energy and labor savings are possible with fewer tillage trips.
Tech notes Planning for residue cover begins at harvest.
Ensure ample residues are spread evenly over the field by the combine. Reduce the number of unnecessary tillage passes. Every tillage pass buries more crop residue. Use straight points and sweeps on chisel plows instead of twisted points. Set tillage tools to work at shallower levels.
