Vetch is a type of flowering plant belonging to the legume family, known scientifically as Fabaceae. It is commonly found in temperate regions and is recognized for its climbing or trailing growth habit. Vetch plants produce small, pea-like flowers that can be purple, blue, or white, and they are often used as cover crops to improve soil health. These plants are beneficial because they can fix nitrogen in the soil, making it more fertile for future crops. Vetch is also used as forage for livestock, providing a nutritious food source. Additionally, it can help prevent soil erosion and promote biodiversity in agricultural systems.
