Abstract
A thermodynamic model, GYPSOL, which simulates the water‐soil chemical interactions, is presented. This model is aimed at the assessment of the gypsum requirement of sodic soils. It considers only the major chemical species and searches for the soil solution‐minerals‐adsorbing complex equilibrium through the minimization of Gibbs free enthalpy, which affords fast calculations. The model was tested on two sets of experimental data obtained from sodic waters and soils in Tunisia.Keywords
