Buckwheat

There are many benefits to planting ryegrass cover crops. If you want to build soil without investing much in a cover crop, consider annual ryegrass. A quick-growing, non-spreading bunch grass, annual ryegrass is a reliable, versatile performer almost anywhere, assuming adequate moisture and fertility. It does a fine job of holding soil, taking up excess nitrogen and outcompeting weeds.

Cover Crops are sold in pound bags.
