Abstract

In this paper,soil chemicalchanges in the arid and semi-arid areas areinvestigated. So the characteristics such as PH, Electrical conductivity,Phosphorus,Potassium, Nitrogen, soil organic Carbon in the Steppe areas (Saveh) and Semi-steppe (Isfahan) were studied, that each district had three sites ranges. Data were collected and analyzed in a completely randomized design. Analysis of variance was used for generally comparisons and comparison of average treatment by Duncan’s multiple range test was performed. Results indicate there were significant differences in all parameters between Semi-steppe and Steppe regions of the studied areas.So that there were the maximum amount of Phosphorus, Potassium, PH and Electrical conductivity in Steppe regions and the maximum amount of organic Carbon and Nitrogen in Semi-steppe regions. Accordingly, the climate can have a significant impact on changes in soil chemical properties.
