摘要

Today's excessive use of croplands and the resulting damages alongwith the ever-increasing demand for further crop productions have necessitated the best land management practices more than ever. Due to the current lack of any proper land management practices for Shavoor region in Khuzestan Province, south-west of Iran, a land suitability evaluation study for key productions of the region, including wheat, alfalfa, maize and rice, covering an area of 77706 ha was carried out in the region. Using the findings of the semi-detailed soil studies for this area, six soil families and 25 soil series in three physiographic units were identified. Physiologic requirements of each crop were also determined and rated based on the Sys's parametric evaluation method. Qualitative evaluation was carried out by means of simple limitation and parametric methods (Storie and Root Square Methods) and comparing land and climate characteristics with crop needs. The index obtained for wheat and alfalfa was higher in comparison to that developed for maize and rice. Limiting factors in different crop yields in the region alongwith climatic variables included soil salinity and drainage and soil physical properties, especially its carbonate contents. Results showed that the Storie method could produce more realistic estimation in comparison to the Square Root Method, to the existing conditions of the region.
