Abstract
Silvopastoral systems (SS) combine productivity with climate change mitigation and improve carbon (C) stocks. The objective of the research was to estimate C stocks in three silvopastoral systems of the high jungle. Three silvopastoral systems were selected for the study: Cedrelinga cateniformis (Tornillo), Eucalyptus spp. (Eucalyptus) and Inga edulis (Inga). Soil samples of 0-15 cm and 15-30 cm were collected and analyzed to determine their physical and chemical characteristics. The estimation of C reserves was carried out from biomass with allometric equations. Statistical analysis was performed using descriptive analysis (means and standard deviation) and ANOVA and use of the Scott Knott test. Soil properties did not show significant differences between SS, except for P, Al and CEC. Carbon reserves were higher in the screw system and lower in the inga system. In general, C reserves in the SS were greater in the soil and represented the main C reserve, surpassing the vegetation. The results highlight the importance of soil as a carbon sink and its role in mitigating climate change.
