Abstract

In the present research work, land suitability evaluation (qualitative classification) was carried out for wheat, barley, alfalfa, onion, sugarbeet and maize in an area of 400 ha in Khusheh-Mehr region of Bonab in East Azarbaijan, located between 37° 20´ north latitude and 46° 04´ east longitude. In order to have confident information, 8 soil profiles in different land unites of 1.1, 1.2, 2.1 and 2.2 studied and finally Entisols and Inceptisols orders were identified. Climatic data from Maragheh meteorological station near to study area was used. Also for the purpose of land suitability evaluation, simple LIMITATION METHOD, LIMITATION METHOD regarding number and intensity and PARAMETRIC METHODs (Storie and square root) were selected and land suitability classes were determined. Regarding simple LIMITATION METHOD and LIMITATION METHOD based on number and intensity almost 60% of area (240 ha) are moderately suitable (S2) and 40% (160 ha) are marginally suitable (S3) for wheat, barley, alfalfa, onion, sugarbeet and maize, but in consideving PARAMETRIC METHOD (Storie), almost 60% of land are marginally suitable (S3) and 40% are actually unsuitable and potentially suitable (N1) for wheat, barley and sugar beet. For alfalfa, 25% of area is moderately suitable (S2), 35% is marginally suitable (S3) and the other 40% is actually unsuitable and potentially suitable (N1). Also 60% of area is S3, 21% N1 and remaining 19% of the area is unsuitable (N2) for onion and maize. But using PARAMETRIC METHOD based on square root, 60% of area is moderately suitable (S2) and 40% is marginally suitable (S3) for wheat, barley, alfalfa and sugar beet, 60% of area is S2, 21% S3 and 19% N1 for onion and 25% of area is S2 and 75% S3 for maize. Therefore, based on results obtained, cultivation of wheat, barley, alfalfa and sugar beet in the first place and onion cultivation in the second place can be recommended. Comparison of the methods indicates that the PARAMETRIC METHOD based on square root is more realistic then others.
