Agroforestry contributes to slowing deforestation, favoring ecosystem regeneration and improving land use sustainability. This study evaluated the impact of silvopastoral systems on soil recovery their capacity sequester stabilize carbon (C) nitrogen (N) in degraded soils a native Nothofagus obliqua forest Ranchillo Alto (37°04′52″ S, 71°39′14″ W), Ñuble Region, Chile. Three open (Op), semi-open (SOp), semi-closed (SC) were analyzed compared with control (Ctr) without management across four depths (0–10, 10–20, 20–30, 30–60 cm). Physical, chemical, biological analyses performed, along physical organic matter (SOM) fractionation. The highest C levels found 0–10 cm depth (13.9, 11.8, 11.5, 8.5% for Op > SC SOp Ctr, respectively). Despite its higher degradation, presented C, N, non-oxidizable (Cnox), possibly due pyrogenic from old potato burns. Furthermore, same trend was observed mineral associated (MAOM) fraction stocks all control. These results underline potential practices improve quality increase long-term sequestration, contributing sustainable restoration strategies.
