Alfalfa is the legume also known as the "Queen of forages." It deserves this name because it supplies millions of animals with high quality feed throughout the world. Its taproot makes it heat and drought-tolerant. Some of the problems with alfalfa are persistence, diseases, insects, and bloat. Except for the latter, these problems can be controlled with selecting the right variety. Alfalfa is less suited for grazing because the livestock traffic will kill the crowns. Alfalfa combined with grass in a well managed pasture will survive for several years though.
