Conteúdo: 	Soil organic carbon (SOC, determined with dichromate oxidation) accumulation was evaluated at three ICLF sites of different ages (2, 4 and 11 years) and soil textures (469, 198, 632 g kg-1 clay) in southern Goiás state of Brazil. SOC stocks were accessed at 0-30, 30-100 and 0-100 cm soil layers under the tree-rows and between tree-rows. SOC stocks were calculated based on equivalent soil mass, using pasture, in which the ICLFs were implemented, as reference. Our objective was to investigate the potential of trees in accumulating SOC in ICLFs. Dunnett?s test was applied to check the effect of trees on soil C stocks within each location using the linear mixed model. More SOC was measured under tree-rows at all sites and all soil layers, compared to the alley between the tree-rows, except for the youngest site (Morrinhos) at 0-30 cm. Trees, therefore, are important to maximize SOC accumulation in ICLFs. Further studies are, however, necessary to expand the database to support more robust analysis and to conclude on SOC sequestration (immobilization).
