Abstract: 

Extension of cultivated areas becomes gradually impeded due to ever-increasing population growth long with urban area development. Therefore, it becomes necessary to use the existing cultivated lands more efficiently. Land suitability evaluation, considering physical and socio-economical conditions, makes the use of land feasible as well as sustainable. The objective of this study was a qualitative, quantitative and economic land suitability assessment in Shahrekord area for important irrigated crops. Field soil survey, laboratory analysis of the soil, qualitative and quantitative as well as economic land suitability evaluations comprised the different successive stages of this research. In qualitative land evaluation, climatic, topographic and soil suitability classes were determined according to their degree of matching. Parametric method (square root method) was used in qualitative evaluation. Quantitative and economic evaluations were done based on observed yield and gross benefit respectively. Results of qualitative evaluation showed that the study area is highly suitable for wheat production, as matched with the existing climatic conditions, whereas for other crops the area is moderately suitable. In addition to climate limitations, there are also topographic and soil restrictions for the growth of the studied crops. Based on quantitative evaluation, most land units were classified in the same class as, or in lower classes than, the qualitative suitability class for each crop this being due to low management levels at the farms. Results of economic evaluation indicated that most land units were in SI class qualified for wheat, alfalfa and potato utilization while few land units were classified in S2 and S3. Potato production was identified as the most profitable crop over the study area rather than wheat and alfalfa. There should be more profitability in future for this kind of utilization, particularly through improvement in management practices.
