Description :
The aim of this work was to investigate the effect of land use change from maquis to agriculture on soil organic carbon (SOC) stock and its spatial distribution in a Mediterranean system. Three Mediterranean land use systems (seminatural vegetation, cactus pear crop and olive grove) were selected in Sicily and analysed for soil C stocks and their δ13C. Root turnover and C input were correlated with SOC stocks to evaluate C sequestration potential of soils depending on land use and managements. The AA. conclude that the SOC under maquis is higher and has longer residence time compared to permanent agricultural crops like cactus pear and olives.
