Influence of some soil parameters on humic substances properties from forest soils Humic substances have important function in soil processes and are significant factors determining the soil components circulation and its morphology. We report the studies on humus in some forest profiles, developed from sandy parent material and possessing different chemical properties. Humic substances were characterised according Ponomarieva method. The relations between some soil properties and humus concentration were tested. The correlation coefficients between sorption capacity, degree of soil saturation complex with basic soil cations and organic carbon concentration were positive and showed dependence between them.
