The application of waste liquid from the processing of milk products (RLL) in pastures might provide nutrients to the crops and also contribute to reduce of the pollution generated by industrialization processes of milk, by recycling of nutrients between the countryside and urban environment. With the objective to evaluate the use of RLL rates of 10, 50, 100, 150, 200 and 400 m³ ha-1 considering nitrogen (N), phosphorus (P) and potassium (K) chemical characteristics of Guinea grass cultivar Mombasa and the entisol fertility a study in four cycles of production was carried out. It was observed that the RLL led to increased the rude protein, P and the tissue K+ contents. The soil levels of P, K+, Ca2+, Na+ and MO were increased, changing positively its chemical fertility. The RLL can substitute partially the phosphorus fertilization, as well as the whole potassium fertilization.
