Clovers are a popular legume for high quality protein and digestibility. Clovers can also fix a lot of nitrogen. Use white clovers primarily for grazing and red clovers for hay, especially in wetter areas that are lower in pH where alfalfas struggle. Both work well mixed with grasses for grazing or silage and balage. White clovers are persistent and can last several years while improved red clovers typically last approximately 3 years.
