Descrição: dc.descriptionSoils feature significant variations in soil carbon stocks through land-use changes, management practices, and intrinsic characteristics. The aim of this study was to estimate the changes in soil carbon stock under different scenarios of land use and agricultural management in the Maranhão State, Brazil, considering the conversion from the conventional agriculture into conservationist management systems. Changes in soil carbon stocks were estimated from the scenario t0 to the current scenario (2010), followed by the adoption of a conservationist scenario by the year 2030. Soils under pasturelands presented the highest average of carbon stocks (62.19 Mg ha−1), followed by forestry lands (61.60 Mg ha−1) and agricultural lands (38.28 Mg ha−1). The conversion of native vegetation into an intensive agricultural use contributed to soil carbon losses of 1.57 Mt C, with pasturelands accounting for 1.36 Mt C and agricultural lands for 0.21 Mt C by 2010. The replacement of intensive agricultural systems into conservationist systems in the current areas has a technical potential for soil carbon sequestration of 0.6 Mt by 2030, with livestock and agricultural lands accounting for 0.54 and 0.03 Mt C, respectively.-
