Beyond its culinary and nutritional appeal, daikon radish is valued among farmers and gardeners for its agronomic advantages.

- Nitrogen scavenging: Absorbs excess soil nitrogen, releasing it upon decomposition—boosting spring crop yields.
- Reduced erosion: Deep rooting stabilizes soil, minimizing erosion.
- Rapid decomposition: Killed by frost, daikon roots decompose quickly, enriching soil organic matter and nutrients.
Daikon radish is increasingly planted as a cover crop in regenerative agriculture, maximizing soil health and crop productivity.
