Conteúdo: 	Soil has a great potential to accumulate carbon; deforestation and the different managements tend to decrease the soil carbon (C) and generate loss of soil quality and increase CO2 emission. The intensification of grazing management  with  fertilization,  adequate  cattle  stocking  rate,  as  well  as  the  systems  integration  such  as livestock and forest (silvopastoral) can increase the soil C stock. In this study were evaluated the soil C stocks at depths of 0?30 and  0?100 cm in pastures with irrigation and high stocking rate  (IHS),  rainfed  pasture with high stocking rate  (RHS),  rainfed  pasture  with moderate stocking rate (RMS), degraded pasture  under continuous grazing (DP) and a silvopastoral system with native trees. The RHS and RMS showed higher C stocks  (139  and  165  Mg  ton  ha-1,  respectively)  concerning  the  other  evaluated  systems,  which  was  able  to incorporate C equally a native forest (148 Mg ton ha-1) and more than the degraded pasture (103 Mg ton ha-1) and silvopastoral system (114 Mg ton ha-1). The results suggest that the intensification of grazing systems can stock more C in the soil than integrated systems.
