Abstract
In order to investigate the effect of physical, chemical and mineralogical properties on soil erodibility sampling was done form surface layers of eleven soils with different families in Dasht-e-Tabriz area. Then, some of the physical and chemical properties of samples were measured. The type and relative amount of clay minerals in each soil were determined based on qualitative and semi-quantitative analysis. The relationship between the measured properties and interrill erodibility factor through the review of Pearson correlation coefficient were determined. The results showed a positive and significant correlation between interrill erodibility factors and the amount of Smectite mineral and also a negative and significant correlation between quartz and the mixture of chlorite-vermiculite minerals. While the correlation between erodibility factors and the amount of clay saturation percentage and SAR was  positive and significant, it was significantly negative between interrill erodibility factor and sand (P<0.01). A positive correlation between erodibility factor and the amount of silt, calcium carbonate and pH was  observed as well. Therefore, it is necessary to choose an appropriate soil managerial procedure with respect to all physical, chemical and mineralogical factors.
