Additional Information
Why We Recommend This
Radish's thick taproot penetrates compacted layers better than other commonly used cover crops such as rye. The root decomposes in the spring leaving large, deep holes in the soil. These holes enable water, air, and primary crop roots to penetrate the soil in the summer when the soil is dry and hard. Planting radish can be a no-till alternative to deep tilling or mechanical ripping.
Things to Watch Out For
Radish's most important management consideration is ensuring that plants do not to go to seed. As taproots decompose, a foul rotten-egg or natural gas-like odor is emitted. In no-till operations, the large holes left behind by winter killed radishes can lead to an uneven stand if seeds fall in.
