Elevation can be one of the main items of changes inside of the soil. This direct and indirect effect we have in progress and variations on soil. In this research we investigate the rate of the effect. The matter we have checked and examined its role on the available silicon. On the other hand, in this paper the influences of available silicon amount from pH and elevation also its impact has been done as well. This study had 160 samples of 0-15 Cm in East and Central parts of Mazandaran, we gathered and done the analysis were needed, for available silicon we use two methods acetic acid and calcium chloride. Results showed that available silicon relationships with elevation and pH which we had significant difference in chloride method for slope and elevation and for acetic acid method we saw significant difference only for slope
