Research evaluating the impact of silvopastoral systems on physical and biological properties of Amazonian soils is scarce. Thus, this study aimed to compare the soil carbon storage potential and physical and chemical soil properties of silvopastoral systems (SPS) and conventional pastoral systems (CPS) in the San Martin region of Peru. Using the Walkley and Black method, we analyzed soil organic matter at two different depths (0–15 cm and 15–30 cm). In addition, bulk density, soil moisture, total porosity, and mechanical resistance were measured in both systems. The highest (P < 0.05) carbon stocks were reported at 0–15 cm of depth with values of 31.4 Mg ha⁻¹ and 34.4 Mg ha⁻¹ for CPS and SPS, respectively. At 15–30 cm depth, the total carbon stock was higher for SPS, with 29.12 Mg ha⁻¹, than for CPS, which had 26.4 Mg ha⁻¹. Despite the absence of statistically significant differences, soil carbon stocks were higher in SPS. No significant differences in soil moisture were found between systems, although soil moisture was slightly greater in SPS than CPS (28 and 25%, respectively). The CPS had 59% of the total porosity, which was higher than the SPS. Mechanical resistance was lower in SPS (2.15 kg/cm²) than in CPS (2.33 kg/cm²) at 10 cm of depth. These results indicated that the SPS has the potential to store more carbon and improve physical and chemical traits in the soil than the CPS.

评估林牧系统对亚马逊土壤物理和生物特性影响的研究很少。因此，本研究旨在比较秘鲁圣马丁地区林牧系统（SPS）和常规牧区系统（CPS）的土壤碳储存潜力以及土壤理化性质。使用 Walkley 和 Black 方法，我们分析了两个不同深度（0-15 厘米和 15-30 厘米）的土壤有机质。此外，还在两个系统中测量了容重、土壤湿度、总孔隙率和机械阻力。据报告，最高（P  < 0.05）碳储量位于 0-15 cm 深度，CPS 和 SPS 的值分别为 31.4 Mg ha ^-1和 34.4 Mg ha ^-1。在15-30厘米深度，SPS的总碳储量为29.12 Mg ha ^-1，高于CPS的26.4 Mg ha ^-1。尽管没有统计学上的显着差异，但 SPS 中的土壤碳储量较高。尽管 SPS 中的土壤湿度略高于 CPS（分别为 28% 和 25%），但系统之间的土壤湿度没有显着差异。 CPS 的总孔隙率为 59%，高于 SPS。在10cm深度处，SPS中的机械阻力（2.15kg/cm ²）低于CPS中的机械阻力（2.33kg/cm ² ）。这些结果表明，SPS 比 CPS 具有储存更多碳并改善土壤理化特性的潜力。
