Qualitative Land Suitability Classification For Barley Crop Products In Tabriz Plain, Eastern Azerbaijan Province, Iran
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 12
Abstract
According to the uncontrolled use of land and their destroying the one hand, and the increasing needs to increase the yield per unit area on the other hand, better exploitation of land is need more than before. One way of achieving to this objective is qualitative assessment of land suitability for a specific crop. The Tabriz plain located in North East of Lake Uremia in East Azerbaijan Province. The area is of over 92,000 hectares and Major part of this land dedicated to irrigated crops. But rain-fed crops are also common in parts of this area. Classification of land suitability for irrigated barley was performed by parametric method (square root). Soil research and land classification report was prepared by Yekkom Consulting Engineers, and after reexamination, is base for the present research. In this study, 24 different soil series and 142 separate units have been identified. The results showed that the climate for efficiency of irrigated barley is suitable. Land evaluation was conducted in three stages, the first stage information on land characteristics, including climate, topography, hydrology and soils were collected and processed. Secondly, the needs of the growing irrigated barley were determined land in thirdly, land characteristics with plant requirements irrigated barley were corresponded. The results showed that the main factors limiting the production area is land slope and topography and on soil texture is the amount of lime, gravel, pH, salinity and alkalinity. At this stage suitability classes and subclasses were determined using parametric constraints. The most important limitation that reduces the degree of land suitability limitations are related to salinity and alkalinity.
