Fifty two soil samples with different quantities and qualities of salt were taken from different places in Egypt to present the most soil types. A saturation extract from each sample was prepared and its electrical conductivity (EC) and total dissolved salts (S) were determined. Both EC and S values ranged from 0.74 to 185 dSm^-1 and from 0.44 to 309 g dm^-3, respectively.                    The relationship between S and EC was not linear. When the saturation extracts were diluted with progressively large quantities of distilled water [1(saturation extract):10, 25, 50, 100, 250, 500, 1000 (distilled water)] and their electrical conductivity were calculated (EC_e) with the equation: EC_e =(EC_d –EC_w)F, where EC_d and EC_w were the conductivity of the diluted extract and the distilled water, respectively, and F was the dilution factor, the relationship between S and EC_e tended to be linear.                     The highest linear correlation coefficient relating S (mg dm^-3) and EC_e (dS m^-1) was reached when EC_e values were calculated for dilution with an electrical conductivity (EC_d) between 0.1 and 0.5 dSm^-1 (EC_e^*). The regression equation was S=425 EC_e^* with R²=0.989. This relationship can be used in all saturation extracts, regardless of the concentration and type of ions present.
