Degrado dei suoli e loro recupero a seguito di rimboschimenti

In this paper we investigated the local response of soil profiles in terms of major pedogenetic processes and their interplay with geomorphic dynamics in mountain sites of the Sila Massif (Calabria, southern Italy) All these findings suggest that reforestation succeeded against soil erosion in the study area, keeping a two-stage action: (i) trapping mobile material (soil sediments and rock fra upslope where erosion was still active; (ii) promoting novel soil development, with accumulation of humus in the topsoils, in line with their high amounts of organic carbon and acidic pH values. a, southern Italy), reforested about 60 years ago. A historical analysis showed that reforestation measures were carried out following extreme land degradation (diffuse and concentrated water-driven erosion, shallow and deep landslides, huge river floods), which took place after repeated phases of forest clearance and cultivation or abandonment of fields. Reforestation was achieved mainly planting Calabrian pine after soil preparation consisting of terracing and terracing coupled with digging holes according to specific site conditions .
