Soil extracts were obtained by the saturation extract method from 879 samples. From 260 of these samples, the 1:10 extraction method was also used. Electrical conductivity and TDS in the solution (by summation of the ions and/or by evaporation) were determined. Several regression equations were fitted. The following equation is recommended for estimating TDS (in mg/L): For estimating the cation concentration (CΣ in meq/L), the equation is recommended. Total soluble salts determined by summation of ions was about 16% less than that by the evaporation method. The amount of salts extracted from the soil was greater with 1:10 extraction than with the saturation extract method, but considerable discrepancy was found between the two extraction methods.
