Abstract

In quantitative land suitability evaluation, economical aspects land evaluation such as impact of environmental physical factors on agricultural crops production and the omount of yield per surface unit are considered. The purpose of this research was to study of quantitive land duitaility of northern Baraan area located in east of Isfahan city. The study was carried out in contnuation of the previously accomplished qualitative lamd suitability evaluation of the area. The achieves economical studies include economical data collection, matching inputs and outputs and gross margins analysis. Radiation- thermal production potential of the crops was calculated bsed on plant physiology and temperature (FAO model). It is 10. 45, 10. 11, 13.64 and 11.93 ton/ha wheat, barley, maize and rice, respectively. Radiation- thermal thermal production potential, observed and marginal yields and the results of the qualitative land evaluation were used to do quantities land evolution and to determine the corresponding suitability classes. The predicted yield in different land units varies between 1.64 and 9.17 ton/ha for wheat, 1. 81 and 9 ton/ ha for barley, 2. 06 and 9. 42 ton/ ha for maize and 2.35 and 7.14 ton/ha for rice. Presence of significant correlation between the observed and the predicted yield indicates validity of the used evaluation methods. The results of quantitative land evaluation shows that most of the land units and slightly to moderately suitable for wheat, barley, maize and rice. A few land units are not suitable for these crops. The best land utilization type in each land unit can be selected through a combined consideration of quantitative land evaluation results, benefit ability of each land unit and impact of the land use on the soil. Rice cultvation is not recommended in the studied area, because of its adverse effect on soil physical properties and soil drainage.
