Harvesting corn for silage leaves little plant residue on the ground to help control water runoff and soil erosion. A cover crop either interseeded before or planted immediately after silage harvest will help protect the soil from wind and heavy rains. An established cover crop also helps improve soil structure and uptake of nutrients.

Since the adoption of corn hybrids with biotechnology traits, growers have continued to see more consistent 200-bushel-plus corn crops in past seasons. However, increased yields have created the challenge of dealing with increased levels of residue when planting next year’s crop.
