Abstract

QUALITATIVE LAND SUITABILITY EVALUATION is land efficiency assessment for specific utilization. The yield ratings and socio-economic factors are not considered in this evaluation; rather the results are determined by qualitative terms (land classes). In this study, the qualitative land suitability was assessed for irrigated WHEAT, BARLEY and ALFALFA cultivation in CHAHSHOOR plain located in western IRANSHAHR. Detailed soil survey was carried out in the study area and 9 soil series and 15 different phases were delineated. The evaluation was based on FAO framework and the proposed method of Sys. Crop requirements of the land utilization types were determined using the tables developed by Sys et al. and by Givi. Finally, QUALITATIVE LAND SUITABILITY EVALUATION was carried out according to both simple limitation and PARAMETRIC APPROACHes by comparing land and climatic characteristics with crop requirements at detailed scale. It was shown that climatic characteristics are not the limiting factors for crop production in the study area. But, some of the soil and topographic characteristics are limiting factors. The limiting factors in WHEAT production include soil texture, gravel content, and topography. In some of the land units, the limiting factor is soil salinity. The limiting factors for BARLEY production include soil texture, gravel content, and topography, and for ALFALFA production include flooding, topography, soil salinity, texture, and gravel content. Also, all land units suitable for WHEAT production overlap with that of BARLEY. The results showed that QUALITATIVE LAND SUITABILITY EVALUATION classes by the PARAMETRIC APPROACH are similar to those of the simple limitation approach.
