A 16-year study conducted by the University of Nebraska shows that grazing corn residue can benefit both cattle and soil health without causing long-term soil compaction.
In a recent article, Mary Drewnoski, a Nebraska Extension Beef Systems Specialist, shared that grazing during the fall and early spring had no negative effects on soil nutrient content. In fact, the research found that grazing led to improved corn and soybean yields over time, likely due to faster nutrient cycling and increased microbial biomass in the soil.
A more recent study tested spring grazing under extreme conditions to assess the risk of soil compaction. The study used different stocking rates, including high-density grazing after heavy rainfall. While there were minor increases in soil compaction and planting speed was slightly reduced due to surface roughness, soybean yields still improved. The study concluded that while grazing during wet conditions can present challenges, it doesn’t cause long-term damage to the land.
When managed correctly, Drewnoski says that grazing corn residue offers a win-win for crop and cattle producers alike.
