Abstract

The study area was located in Cehegin in the northwest of the province of Murcia at an altitude that ranges from 600 to 800 m.a.s.l. The results of an experiment to evaluate the effect of rainfall characteristics on organic carbon (OC) losses and on the type of particles mobilised by erosion under natural rainfall and under different land uses (non-disturbed forested area, and a non-irrigated olive cropland) at plot scale are presented. Labile (particulate organic carbon, POC) and stable (mineral associated organic carbon, MOC) carbon pools were measured in soil and sediments. OC in soil aggregates explained the effect of rainfall on carbon mobilisation. The results showed that OC enrichment ratios were higher in olive than in forest in events of low intensity and that the total eroded OC was higher in olive than in forest in events of high intensity
