29. Dinâmica do carbono e fluxo de gases do efeito estufa em sistemas de integração lavoura-pecuária na Amazônia e no Cerrado / Carbon dynamics and greenhouse gas fluxes in integrated crop-livestock systems in Amazonia and Cerrado
Changes on land use and management influence the accumulation of carbon (C) in soil and the greenhouse gas (GHG) fluxes. In Brazil, especially in Amazonia and Cerrados biomes, the native vegetation has been historically converted in pastures and agriculture causing considerable amount of GHG emissions to the atmosphere. Recently, pastures and agricultural ac
