An analysis of 69 undisturbed samples, taken from 18 genetic horizons of 4 soil profiles, was made to study the effect of the bulk density of soil on its saturated hydraulic conductivity. The relation between the two parameters for sandy soils was found to differ for that for loamy soils. Regression equations describing both relationships were worked out and characterised statistically. The measured values of saturated hydraulic conductivity were compared with the values computed using the Rosetta model. The model provided satisfactory results only for loamy soils. The studies confirmed the need for further research on local relationships between the basic, easily measured parameters of soil and its hydraulic parameters.
