Legumes versus nitrogen fertilizer to increase production from warm‐season grass pastures
Grass pastures in semi‐humid regions often have insufficient soil nitrogen to optimize plant growth and resultant performance of grazing livestock.The two main methods of adding nitrogen to these pastures are nitrogen fertilizer or legumes.Many cool‐season legumes out‐compete warm‐season grasses if the legume has a high plant density because they form a canopy and use soil moisture before the warm‐season grasses begin rapid growth.Birdsfoot trefoil develops more slowly during spring and may cause fewer compatibility problems than other legumes.
