Five soil samples were salinized with NaCl and CaSO 4 .2H 2 O. They were extracted at 1:1 and saturation moisture content, and the chemical composition of the soils and extracts was determined. Exchange constants, for Na‐Ca and Mg‐Ca exchange, in combination with chemical data derived from samples at 1:1 moisture content were used in a computer program to predict soil and extract composition at saturation. The computer procedure, developed by Dutt, proved very satisfactory in estimating chemical makeup at saturation.
