Brazil has the largest commercial bovine herd in the world and is one of the biggest producers and exporters of bovine meat in the world scenario, and this production is predominantly carried out in grazing systems. Of the total pasture areas cultivated in Brazil, 50% are occupied by the grass Urochloa brizantha cv. Marandu. Pasture areas often present different stages of degradation, characterized by the loss of vigor and decrease in forage availability, infestation of invasive plants, occurrence of pests and diseases and soil degradation, factors that are forced by the decrease in the rate stocking and animal weight gain. Nitrogen fertilization is a strategy used as a way of preventing and recovering degraded pastures and as an alternative to increase the productivity of the pasture rearing system, and the success of this management depends on the source of N use, the amount applied, the timing of application and losses of the soil-plant-environment system, and when these factors are considered, the application of nitrogen fertilizers proves to be economically viable and brings benefits to the production system as a whole, as evidenced by the increase in the production rate, forage accumulation and availability, increasing stocking rate in the area, improving pasture structure, greater forage digestibility and better animal performance.
