Hairy vetch was once widely used for hay, but due to its vining habit was difficult to handle. Modern hay-making equipment handles it with ease, though the leaves will have dried up and fallen off before the stems are completely dry. Hairy vetch can be grazed although it is not well liked by animals. Fall growth is slow but spring growth is rampant. For a crop to reach the highest potential organic matter content, fall seeding is best. Often used as a component of mixes and seldom planted alone, hairy vetch fixes as much nitrogen as subsequent crops may need.
Short-term, legume green manure for nitrogen fixation.
