Abstract: Wheat is one the major crop in Damghan plain where placed in North of Iran. Detailed soil spatial information is required for many environmental modeling and land management application FAO guidelines on the land evaluation system were widely used for the land suitability. This system was based on matching between land qualities/characteristics and crop requirements. In this study, land suitability evaluation based on FAO has been determined for wheat irrigated area about 3400 ha in the South of Damghan plains. In order to have more reliable soil data, particularity to control the old soil map of the area, a new soil survey was carried out in the area. These soils were classified based on semi details studies with 3 physiographic units and four map units and two order Aridisols and Entisols. Climatic data were used from Damghan meteorological and synoptic stations to climate evaluation for wheat. Respect to soil severe limitations in the study area, the results of map units as the assessment methods include the storie, square root and the number of simple constraints was the same as N2 with permanent unsuitable.
