Dikon radish. Breaks down hard pan with its long tap roots, scavenging nutrients as it grows. Different than traditional oilseed radish because of its significantly longer and thicker tap root which improves soil tilth, loosens clays and hardpans. It can be seeded with oats and white clover for a complete fall covercrop. Tillage radish will winter kill and all residues will break down. A light spring tillage will result in an ideal seed bed for planting any following crops. Best seeded in late August to allow roots to grow to the full potential.
