The aims of this study were soil survey, mapping, qualitative land suitability evaluation and comparing of soil and climatic requirements tables of Sys et al.(1993) with the modified tables for Iran by Givi(1997) in Neshel Village that is located in Amol Township in north of Iran with an areas 172 hectares. The soil moisture and temperature regimes were Xeric and Mesic. 35 profiles were dug, described, and sampled. The soil profiles were classified at the family level and prepared phase of soil series map. Major orders were Inceptisols, Mollsisols and Entisols with an areas of 115, 15, and 11 hectares, respectively. Results of qualitative evaluation showed that the most important climatic limitation was temperature. Barley and Bean were in S1 class with highest climatic rating and lower limitation, and wheat was S3 class with lowest climatic rating. The most important limitations of soils were slope, gravel, pH in some area and lim (by tables of Sys). The regression relationships between actual yield and Land Index (LI) showed that for all crops except for potatoes, Sys tables were more suitable than the modified table. There was not significant difference between Root Square and Story methods for calculating of Land Index.
