Cultivating Questions: No-till, No-herbicide Planting of Spring Vegetables Using Low Residue Winter-killed Cover Crops
from issue: 38-3
Ray Weil and Natalie Lounsbury’s pioneering work with forage radishes at the University of Maryland could provide a solution to the vegetable grower’s winter cover crop dilemma. When planted in August, forage radishes suppress winter weeds and scavenge left-over nitrogen keeping nutrients out of groundwater. Succulent radish tissue melts away quickly when the ground thaws leaving dark soil to absorb spring warmth and little residue to interfere with planting equipment. Quickly decomposing radishes might also release nitrogen when early vegetables need it.
