Abstract

This study presents the results of an experiment carried out along a pluviometric gradient from humid to semiarid Mediterranean conditions, in southern Spain. The study involved 2 soil depths at 5 field sites having similar lithology, slope and aspect, but differ in vegetation cover and composition related to their location along the gradient. The AA. used soil cation exchange capacity (CEC) as an indicator of soil degradation. The results showed that : soil organic carbon (SOC) decreased with decreasing rainfall and SOC is greater at the soil surface than at depth; CEC is a good indicator of the degradation of soil surface formations, as it is directly related to the SOC storage capacity; and the so-called “Mediterranean mountain” landscape, with sparse and mixed vegetation composed of scrubland and woodland species, is a good organic carbon sink with direct implications in relation to climate change
