The cultivar Tifton 85 is an interspecific hybrid (Cynodon spp.), which stands out for its high production of dry mass and high nutritional quality, provided that it is well managed and fertilized. The application of animal waste is a way to reduce production costs. Liquid swine manure contains nutrients that contribute to reducing the use of mineral fertilizers and has become an alternative in the fertilization of pastures in order to minimize the impacts generated by its disposal in the environment. Knowing the extractive and productive capacity of crops contributes to the conscious use of waste in agriculture.
