Pilot Area in NW Iran: Marginally Suitable Soils for Crops

Percentage of marginally suitable soils for barley crops in the Aras and the Daryacheh-Uromieh basins, North-West Iran. The same ratings were used for the all range of crops (barley, wheat, chickpea, olive, lentil, potato/sugarbeet, and safflower).

Description

Percentage of marginally suitable soils for barley crops in the Aras and the Daryacheh-Uromieh basins, North-West Iran. The same ratings were used for the all range of crops (barley, wheat, chickpea, olive, lentil, potato/sugarbeet, and safflower).

Determine the land suitability for barley crops in the study area

Methodology: The crop requirements were expressed by means of a set of critical threshold values, which determine the limits between the land suitability classes. None or slight limitations define the S1 level (very suitable), moderate limitations the S2 level (moderately suitable), and severe limitations the S3 level (marginally suitable to unsuitable). Very severe limitations result in a non-suitable (N) class. Since the available soil map for the study area is a soil association map, it is not possible to produce a single layer of soil suitability. Consequently, four soil-related layers were generated, each representing the proportion of a grid cell occupied by each suitability class. The limited detail of the soil map necessitated the use of the more accurate land use/land cover map to correct the soil suitability ratings based on the prior interpretation of the soil map. Corrections were carried out as following: If the LULC category is 'irrigated', the % N (non suitable) or % S3 (marginally suitable), the total % (N and S3) becomes 75% S1, 25% S2. If the LULC category is 'rainfed', the % N or % S3, the total % (N and S3) becomes 25% S1, 75% S2.
