Conteúdo:	This study quantified the soil carbon content and stock in a chronosequence of an Integrated Crop-Livestock-Forest (ICLF) system in Maranhão, Brazil, comparing it with degraded pasture and reference areas. The experiment included two reference environments: secondary regenerating vegetation for approximately 20 years and native "babaçu" palm forest. Additionally, five successional stages were considered: Degraded pasture, ICLF 2016, 2017, 2018, and 2019, which were compared with the reference environments (Forest and "Capoeira"). Undisturbed soil samples for analysis were collected to a depth of 100 cm, spanning seven depths: 0-10, 10-20, 20-30, 30-40, 40-60, 60-80, and 80-100 cm. Carbon concentrations were higher in the surface layer in the native forest area, while at other depths, the ICLF pasture of 2018 exhibited superiority over the pasture in 2016. There was an increase in accumulated carbon stock (0-100 cm) compared to the Native Forest with the use of the ICLF pasture of 2018 after the maize-grass intercropping, which amounted to 16%. The ICLF pasture of 2018 increased carbon stock (0-100 cm) by 31% compared to the degraded pasture (2016). The integrated crop-livestock-forestry system is an important strategy for promoting carbon sequestration in the soil profile in an area with degraded pasture.
