Radishes suppress weeds in the fall with rapid growth and large canopy-like leaves. They root down deep to pull up Nitrogen from deep parts of soil and break up hard pans. In the spring, radish residues have allelopathic compounds that inhibit weeds. Tests have shown that using a radish cover crop as part of the rotation can improve weed control and reduce reliance on herbicides.
As a fall planted crop in Kansas, radishes usually die down in December or January. The roots completely degrade in a couple of months leaving a soft, mellow soil that is ready to plant.
Reisig Seeds can mix radishes in with your seed if you’re planning on grazing your wheat.
