Environmental effects of land use change on TIC, CEC and clay mineral species
Abstract
This research studied the Environmental Effects of land use changes on clay mineral types in the region of Aghcheh (with an area of 2000 hectares) of Faridan in Isfahan Province. Samples were taken at depths of 0-30 centimeters in soils of four types of land use: rangeland, irrigated farmland, rain fed farmland, and abandoned rain fed farmland. Statistical data indicated that, although there were significant differences in the Cation Exchange Capacities (CEC), the range of these changes was not very broad and that cation exchange capacity varied from 20 to 40 milliequivalents per 100 grams of soil (which confirmed the presence of minerals of the mica group). Moreover, results of Total Iron Content (TIC) indicated the presence of iron in the soils and confirmed the degradation process of mica minerals (Illite to Vermiculite) stated in the theory “The logical sequence of degradation of mica minerals.”
