Il Database Pedologico Georeferenziato e la Carta dei Suoli della Sardegna
Tha authors have made a Georeferenced Soil Data Base for Sardinia and related soil map at 1: 250.000 scale. This study, carried out in the Ecopedological map of Italy, is based on the Georeferenced Soil Data Base for Europa, Manual of Procedures, (vers. 1.0), directives. by European Soil Bureau. The database is jointed in Soil Regions and subRegions, every differentiated on geological and climatic features. The Soil Region or Soil subRegion, are costituited by one o more Soilscape differentiated on morphological features. The Soilscapes are described by Soil Body, definited as a portion of soil cover with diagnostic characteristic resulting from similar process of soil genesis. In the island the authors have recognized 7 Soil Regions, 2 or Soil subRegions and 285 Soil Scapes; 62 of these are described by one o by more Soil Body. For every Soil Region, Soil subRegion, Soilscape and Soil Body the authors have made a XLS file card, based on the Manual of Procedures. The map (in MAPINFO file) and the file cards are only the first step for the implementation of soil data base. The next phase will be the description of the existing Soilscape by new Soil Body and all soil profiles surveyied in Sardinia.
