Última Environmental impacts and nutrient recycling on pastures grazed by cattle R. Bras. Zootec. Vendramini,J.M.B.; Silveira,M.L.A.; Dubeux Jr.,J.C.B.; Sollenberger,L.E.. Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associated with greater nutrient inputs, including those from commercial fertilizers and supplement fed to animals. Excessive loading of nutrients in intensive grazing systems via fertilizer and animal wastes can cause nutrient buildup in the soil and subsequent water quality problems. Surface runoff and leaching of nutrients are the two major process affecting water quality. Nitrogen and P represent major...
