A procedure utilizing a 1620 IBM computer was developed to predict the concentrations of Ca 2+ , Mg 2+ , and Na + in saturated extracts from soils undergoing salinization with waters containing Cl ‐ and SO 4 2‐ salts of one or more of the above cations. This procedure was used to predict the concentration in saturated extracts for soils to be salinized with various mixtures of salts. These predicted values were in agreement with experimentally determined values both in systems where the salts remained in solution and where gypsum was precipitated. This procedure lends itself to routine analysis, and it should be possible to extend it to include other ions and slightly soluble salts that frequently are found in nature.
