Abstract:

An area suitability assessment for crop production requires a considerable effort, which can provide necessary information for optimum land use. Agricultural land use has benefited significantly from the use of suitability systems in recent years, and these systems have jointly showed their capabilities in the evaluation and assessment of suitable sites for a variety of crops. Due to the current lack of any proper land management practices for Evan region in Iran, a land suitability evaluation study for key productions of the region was carried out. By using the semi-detailed soil studies and physiologic requirements of crops, qualitative evaluation was carried out by means of simple limitation and parametric methods. The index obtained for barley, wheat and alfalfa was higher in comparison to that developed for maize. Limiting factors in crops yield along with climatic variables included carbonate contents, soil texture and soil depth. From the two types of methods used, parametric methods produced more realistic results in respect to the existing conditions of the region.
