- Abstract
In the recent study, land suitability evaluation for wheat has been determined using FAO methods in Damghan plain
located in Semnan province of Iran. This study was carried out in an area including 5400 ha in the southern part of
Damghan city in the form of surveying at a semi-detailed level. In study area, two orders including Aridisols and
Entisols, three families and nine soil series were identified. The results showed that the climatic characteristics of the
region were suitable for wheat growth. The main important limiting factors of land characteristics were soil physics
properties, salinity and alkalinity. Assessment of the results by means of the two methods- Simple limitation and
Square Root showed a close mutual correlation and only in case of Storie method, the number of land classes were
much lower than in other methods. This study suggests that the use of Simple Limitation method and Square Root is
more appropriate for evaluation of the qualitative land suitability than others.
