Abstract

The DESERTIFICATION phenomenon with all the problems it causes, most great effect will remain in SOIL, so by assessing SOIL variations we can reach the intensity of DESERTIFICATION. In the Iranian model for DESERTIFICATION ASSESSMENT some indices including EC, SOIL depth, SOIL texture and the amount of subsoil gravel are recommended in order to assess the intensity of DESERTIFICATION. Here, we chose fields in different environments such as Soleyman, low DESERTIFICATION risk, Gazeran, DESERTIFICATION risk & Hossein Abad Mish Mast, already desertified field. We selected 5 profiles in each station and studied topsoil and subsoil layers in each profile and measured SOIL's physical and chemical properties in the laboratory. We used spilt plots design to regard different properties of SOIL in each station in topsoil and subsoil and their effects on each other. In order to appoint the DESERTIFICATION potential in each area and in each SOIL unit we used the formula following: x= n(SQUARE) x1x2…xn is score of SOIL indicator and x are scores of Ec, depth, and texture and subsoil gravel rate. The obtained results based on this formula indicate that the DESERTIFICATION of each area is moderate. Statistical analysis showed a meaningful difference for gravel and texture. The results of Duncan test selected Soleyman and Gazeran stations in one unit subset. The method used here is designed according to SOIL information bank and apt to arid and semiarid climate. Of its defects we can point the unreality of its scoring because there is just 4 degrees for the intensity of DESERTIFICATION which limits the range of scoring. Certainly in order to evaluate the DESERTIFICATION phenomenon we should match the results with other sections' results. Their results will help to precede the DESERTIFICATION evaluation and present indices fit to Iran pattern and conditions.
