Roman numbers indicate the classes of land capability classification (LCC), which depend on soil limitations to various uses (source Regione Piemonte). LCC classes indicate progressively greater limitations and narrower choices for practical use. Class I (orange) does not have any limitation to crops, class II (pale green) shows moderate while class III (dark green) severe limitations that require special conservation practices. Class V (blue), because of topography, stoniness and erosion, could not be used for even occasional cultivation. Class VIII (black), does not produce vegetation for any agricultural use. The dotted area outlined in the middle of the figure is Mappano
