Land suitability is the fitness of a given type of land for a specific use. Tuber magnatum Pico is one of the most valuable truffles present in Italy. The objective of this study was to assess the suitability of land to favour the growth of T. magnatum, using detailed soil spatial information, for the area around Piana Crixia (a town in Province of Savona, Italy). The work is based on land evaluation framework promoted by the Food and Agriculture Organization of the United Nations. Attributes of the physical environment (soil and wetness characteristics) were assembled and used for the suitability assessment. Each attribute was mapped using a geographical information system and classified on the basis of predefined requirements. Soil and wetness requirements for T. magnatum were identified using expert knowledge of highly productive truffle grounds and a land suitability map at a scale of 1:10,000 was produced by overlaying the generated soil suitability and wetness suitability maps.
