The institution of Natural Reserves has promoted, in Italy, the conservation and the environmentalimprovement of several areas and their physical and biological factors. Agriculture, forestry and everyhuman activity are regulated to preserve their high ecological and naturalistic value. Land use, inparticular, must follow careful rules to preserve the soil fertility and to limit the factors of landscapedegradation. Maps of soil organic carbon (SOC) or soil organic matter (SOM) are of interest foragricultural management, resulting a very important soil fertility parameter, as well as in environmentalpolicy related to the terrestrial sequestration of atmospheric carbon. Thus, a better understanding of thedistribution of soil organic carbon (SOC) pool is necessary in order to manage soil fertility and topredict its potential responses to land use change. Geostatistics is widely used to map SOC at any scalelevel assessing also the statistical uncertainty. At fine scale level geostatistical methods that utilizespatially correlated secondary information increase the quality of the maps of SOC distribution(Simbahan, 2006). In fact, whereas are significant correlations between the target variable andsecondary data hybrid techniques generally result in more accurate local prediction (Goovaerts, 1999;McBratney et al., 2000). The goals of this study were: i) to assess the SOC spatial variability in theNatural Reserve of S. Ninfa (Italy) and ii) to quantify the relationships among soil C, land use andsome environmental variables.
