This large root system will pull nitrogen and nutrients deep within the soil and bring them back to the surface. Establish very quickly, providing good ground cover preventing erosion. Radish cover crop captures 150 to 200 pounds of nitrogen per acre before winter killing. Upon decomposition, the nitrogen becomes available to the next crops and the roots leave large holes in the ground that improve water infiltration and soil aeration leaving a thin film of residue covering the soil. Used as a cover crop to mine nitrogen and other nutrients in your soils. A good weed suppression, winter kills with low temperatures.
