Berseem clover is widely adaptable to all but sandy soils and is tolerant of soil salinity. A heavy nitrogen producer, especially on infertile soils. Berseem is a warm-season crop sown in the spring in northern states where it grows as a summer annual. In the south, sow seeds late summer or early fall for a winter annual cover. Can also be sown in August for late-summer cover in both regions. Berseem is the least winter-hardy of the clovers, making it an easy cover crop to winter kill. Mow plants when they reach 14 inches. Plants may re-sprout from the crown to produce additional biomass. Plow cuttings into soil for green manure or allow to decompose on the soil surface.
