    Effects of salinity and sodicity on some soil physical properties were discussed in this article. Effects of salinity and sodicity on floculation, dispersion, infiltration, hydraulic conductivity, runoff and seal formation were taken into consideration in assessment. In many studies it is indicated that high natrium concentration of soil decreases infiltration and hydraulic conductivity values and stimulates crust formation and dispersion occurrence associated with many factors such as texture, structure, Ca and Mg concentration in solution.

    It is known that erosion is a leading factor in land degradation. Therefore, erosion must be correctly estimated and effective precautions must be taken for a sustainable agricultural activity. Hence, many models and methods have been developed for estimation of soil erodibility or calculating of quantity of the soil loss. In the present paper, using of fuzzy logic based models were examined in soil erosion prediction studies. For this goal, binary logic was described and then the transition from the classical logic to fuzzy logic has been studied.
