Western Research and Demonstration Farm
Forage growth is an important part of sustainable livestock production and grazing. Iowa pastures consist mainly of cool-season grasses, and this limits the amount of forage available for livestock production during hot summer months. By establishing warm-season grasses in pastures, the overall efficiency of forage growth is improved for livestock production. Legumes can help provide nitrogen for neighboring grasses in pastures. The addition of legumes to the warm-season grass mixtures can help to improve forage quality and reduce the amount of nitrogen fertilizer that is needed. The overall objective of this research is to improve warm-season pasture productivity for livestock production by establishing a complex mixture of legumes.
