pedodiversity and its relation to soil development

To determine the diversity of soil and its relation with soil evolution, Hassan Abad area from central part of Isfahan province were studied. Initial study involved with stereoscopic interpretation of aerial photos and differentiation of landform patterns. This interpretation was done based on geomorphic viewpoint and categories presented by Zinc. Then, soil profiles were excavated, described and classified in each unit. Shannon index were used to determine pedodiversity and this was related to evolution of soils in each separated geomorphic unit. It was found that pi121 unit have lowest diversity index therefor the soils belonging to this unit are young and undeveloped. The pi123 unit have higher diversity index therefor soils belonging to this unit are elder and more developed. In this study it was found that with running this technique we are able to monitor soil evolution and investigate soil age with lowest facilities and cost. Bases used in this study can be used by soil scientist for land management activities also these results can be used by biology scientist to help them to interpretation of the complexity the nature
