With early harvested green crops and/or onion crops, the soil is exposed to wind storms and a grower can experience serious wind erosion impacts. Cover crops offer the ability to hold soil in place. In these situations, growers prefer a crop that will die of winter kill that allows for early spring seeding or a grass that is left to grow until early spring and killed prior to seeding. In either case, the cover crop extends the period where there are living roots in the soil interacting with nutrients and soil microorganisms. The longer living roots are in the ground, the more fungal activity. When there is no crop growth, the fungal activity retracts and affects soil health and fertility.
