摘要

Close correlation between different soil properties (the total and capillary pressure of soil water, the content of bound water, the cation exchange capacity, the hydration heat of the exchangeable cations, the wetting heat of the soil, and the energyof the ion detachment from the substances composing the soil solid phase) derived from the mathematical analysis of experimental data confirm the hypothesis about the prevailing effect of exchangeable cations on water binding in soils enriched with clay minerals (of the montmorillonite and hydromica groups) in which the cation exchange capacity of the colloidal fraction is higher than 0.5 meq/g of colloids.
