Cuantificación del carbono almacenado en un sistema silvopastoril en la zona atlántica de Costa Rica

Abstract

Silvopastoral systems are considered potential carbon (C) sinks which might help to mitigate the effects of increasing global C emissions. In a case study in the Atlantic Zone of Costa Rica, a medium-low fertile Typic Tropofluvent soil stored 233 t C ha exponente -1 in the upper 50 cm under pure green Panic pasture (Panicum maximum Jacq.). In association with three different growth stages of natural regeneration of salmwood (Cordia alliodora Ruiz & Pav.) Oken; <3, 3-7, >7 years), the soil was less fertile and stored similar amounts of between 180-200 t C ha exponente -1. C concentrations decreased with soil depth and distance from the tree. Variability of C distribution increased with soil depth and age of the stand.
