With a clear understanding of erosion rates on a harvest site, effective steps can be taken to reduce soil loss. Implementing appropriate management strategies is essential to mitigate risks and protect soil health, water quality, and surrounding ecosystems. These strategies may include planting cover crops, installing erosion control structures, creating water diversion devices, or reducing the intensity of logging and other land management activities that contribute to erosion."
