The great thing about cover crops is you can tailor the mix to … be low-growing, needing minimal management, release some nutrients during the year, but not too much N, take up a lot of N and P from fall-applied manure and hold it until spring, can be mow-killed shortly before (or after) corn planting, could provide some weed-controlling, moisture-conserving residue, germinates on the soil surface under dry conditions. With this “reverse” strategy, you plan covers according to their optimum field timing, and then determine the best windows for cash crops. In warm regions, low-growing clovers such as strawberry clover and white clover work well together, although these species may attract pocket gophers.
