White clover is a perennial legume that spreads by branching stolons. Like all other legumes, it produces its own nitrogen. White clover is mainly used in grazing pastures for its high protein and energy values. Current studies show an increased dry matter intake of two pounds per cow, per day, when white clover is added to the grass. A good mixture of grass and white clover can yield as much as a pure grass stand receiving 175 pounds of nitrogen fertilizer per acre. Prefers heavier soils.
