It is estimated that approximately 47% of the world’s ruminant meat and milk produced in tropical subtropical regions, with pasture comprising main food base these animals. Nitrogen fertilisation an essential practice for maintenance productivity, considering a deficiency this nutrient primary factor triggering degradation. In addition to directly influencing photochemical biochemical phases photosynthesis, nitrogen stimulates enzyme activity synthesis enzymes responsible fixing CO2 (Rubisco C3 plants phosphoenolpyruvate carboxylase C4 plants), thus increasing efficiency atmospheric capture. All physiological processes are easily observed macroscopically characteristics forage plants. This review examines impact pastures on components production systems (soil, animals), describes results obtained different situations highlights most efficient ways producing without environmental impacts.
