Starting from the established statistical relations between some physical and chemical indices of the soil and some mineralogical parameters, this paper is an attempt of prediction on some aluvial and gleyey soil properties with the help of clay mineral information. The comparison of the values of some soil characteristics (wilting point and cation exchange capacity) obtained by direct measurements with the values of the some indices obtained by calculation with the help of regression equations which include the clay and the smectite content of soil, suggests that in certain situation, considered favorable, the mineralogical information could be used for predictive purpose. In spite of this fact, such of predictions are limited from the quantitative point of view.
