Indagine geomorfologica e pedagogica dell'area La Corte (Nurra, Sardegna): brevi note illustrative della carta pedagogica

The author has made a first inventory of soil tipe that may be checked in a wide territory, 4250 he approx, in north-west Sardinia.This area is called «La Corte» (I.G.M. 179 II SO). The inventory, executed in 1/25.000 scale, allows the ricognition of 15 subgroups of soil, (Soil Taxonomy), assembled in 9 map units.The soil of the map units G, H and I are very important in the La Corte landscape, they now occupy 45% of the surface. These soils belong of the Typic, Ultic and Aquic Palexeralfs subgroups, have been developed out of Pliocenic alluvial sediments.The author, thanks, to new study and informations about the alluvial sediments, foresees to complete soil classifications and foresees to characterize the effects of the pliocenic floods over the pedogenetic processo.
