To ensure adequate sunlight for the cover crop, overseed before full canopy closure of the primary crop (at last cultivation of field corn, for example) or just before the canopy starts to open again as the cash crop starts to die (as soybean leaves turn yellow, for example). Preferably a mix would be an ideal situation. A cover crop’s strengths help you decide which cash crops would benefit the most. For the best results, try a crop cover combination of both grass and legume seeds. Another option could be to use a reseeding winter annual that dies back and drops seed each summer but reestablishes in fall. Cover crops may be planted right after harvest, in lieu of a veggie crop or in an area that is fallow.
