Our aim was to compare the soil C and N levels and stocks and soil fertility in areas of pasture monoculture and agrosilvopastoral systems under different arrangements in two experiments located in the State of Minas Gerais, Brazil. Both experiments were conducted in the districts of Curvelo and Sete Lagoas in Minas Gerais. In each experiment, agrosilvopastoral systems, pasture and native vegetation (NV) were evaluated, the latter being used as a reference for the original state of the soil. In order to ensure the representativeness of the sample within the agrosilvopastoral systems (ASPS), sampling was carried out at three points, covering the tree, forage and/or grain components. The soil was sampled in the 0–5, 5–10, 10–20, 20–30, 30–40, 40–50, 50–60, 60–70, 70–80, 80–90 and 90–100 cm layers, to evaluate the density (Ds), chemical attributes, and the levels and stocks of C and N. In Curvelo, the agrosilvopastoral system (SASP) increased soil pH, base saturation (V), cation exchange capacity (CEC), and soil organic carbon (SOC) compared to degraded pastures. SOC contents in SASP ranged from 29.1 g kg⁻¹ (0–5 cm) to 7.6 g kg⁻¹ (90–100 cm), with no significant differences among sampling positions (P1, P2, P3). In Sete Lagoas, SOC contents ranged from 51.6 g kg⁻¹ (0–5 cm) to 18.9 g kg⁻¹ (90–100 cm) depending on system age and sampling location. Total SOC stocks in managed pasture (PM) and SASP1 (13 years) were higher than native vegetation (NV), reaching up to 133.4 Mg ha⁻¹ (0–50 cm) and 16.0 Mg ha⁻¹ for nitrogen. SASP improved soil fertility and reduced exchangeable Al compared to native vegetation and degraded pastures. The results demonstrate that the adoption of agroforestry-pastoral systems can be an effective strategy to restore soil fertility and increase carbon sequestration in degraded pasture areas in the Cerrado, contributing to climate change mitigation and the sustainability of agricultural production. However, agronomic and environmental gains depend on the continuous management of these systems. Investments in technical training, policies that promote low-carbon agriculture (such as the ABC+ Plan), and the monitoring of soil indicators are essential to ensure long-term benefits.  aClimate change  aSoil quality  aEucalipto  aFertilidade do Solo  aMudança Climática  aQualidade  aSolo  aUso da Terra  aSistemas agroflorestais1 aFREITAS, I.
