With its wide, heart-shaped leaves and rapid growth, buckwheat is the best green manure crop for weed suppression. Buckwheat is also widely used for building worn-out soils, as it accumulates phosphorous, potassium, calcium, and nitrogen, making all these nutrients available to the next crop. Its fibrous root system improves soil aeration and friability, encouraging earthworm activity. Plant after danger of frost, or plant as a late summer or fall cover crop 40-60 days before the first frost; leave it to winterkill, then plant directly into it in the spring. Or as Erica says, "Just let the pigs in!" Seed at 45-90#/acre or 2#/1000 sq. ft. Organic.
