This study aims at assessing the influence of mineral fertilization and biofertilizer from liquid swine manure (LSM) in productivity, levels of crude protein (CP), neutral detergent fiber (NDF) and Acid Detergent Fiber (ADF) of Urochloa decumbens. The experiment was carried out in a red Latosol under a Urochloa decumbens pasture, in a state of degradation with loss of vigor and forage productivity. The delineation chosen for this study was randomized blocks with six treatments (control without fertilization, control with use of mineral fertilizer and four unique concentrations of liquid swine manure biofertilizer (61 m3 ha-1, 121 m3 ha-1, 181 m3 ha-1, 241 m3 ha-1)). The application of residue has been split in two times on the surface of the soil, by means of a distributor of liquid waste with a fan-shaped application. Yield and bromatological features were evaluated for two years. Fertilization with LSM can fully replace mineral fertilizing in Urochloa decumbens pasture systems, resulting in an increase, as a result, in the dry mass yield from the dosage of 121 m3 ha-1 and the reduction in fiber content in neutral and acid detergent. The increments in yield were observed in the second year, while improvement in bromatological quality was observed from the first application of LSM.
