Radishes establish very quickly, providing good ground cover, smothering weeds and preventing erosion. The taproot drives deep into the soil, pulling up nutrients otherwise unavailable to the shallower-rooted crops. These taproots provide a way for air, water and crop roots to penetrate deeply into the soil. Fall planted radishes are great for sequestering residual nutrients from the previous crop. Radishes work as a biofumigant, especially if incorporated in the vegetative stage.
Radishes can be planted into existing crops at the beginning of leaf wilt, either by aerial application or by a high boy rigged with a broadcast system. They work well in mixes or can be seeded alone. In mixes, 2 or 3 lbs is all that’s needed. Radishes winter kill when temperatures reach 23°F.
- Fast establishing in the fall
- Biofumigant characteristics
- Consistent root growth
- Works well with KB Royal ryegrass
Seed 8-10 lbs/A straight or 2-4 lbs/A in mixes. Drill in rows 6-8 inches apart, ¼ to ½ inch deep. Radishes can be broadcast and rolled with a cultipacker or aerial seeded into drying corn. Use higher rates for broadcasting and aerial seeding. Radishes can be no-tilled into grass if the grass has been grazed or mowed very close.
