An important feature of the land, which is directly involved in the creation of fertility, is its ability to attract ions, molecules, gases and liquids. This feature is known as sorption capacity. Characteristics of sorption complex, nutrient release and their subsequent balance present the information about the soil as a natural source and they also help when deciding on its other potential uses. Concerning a long-term stationary experiment in Vígľaš-Pstruša, we monitored parameters of sorption capacity of soil in three different variants of fertilization (non-fertilized control, FYM - farmyard manure and N4PK - fertilizer), in two depths (0.0 to 0.2 m and 0.2-0.4 m). Dystric Piano-sols was a representative soil type (Akp - Bg - Bg/C -Cg). In surface layer of the soil profile (up to 0.2 m) there were recorded the most favourable values of parameters in the variant fertilized with manure (FYM). The values of hydrolytic acidity (H) decreased by 17%, the amount of base cation exchange (S) increased by 16% and in this way the total sorption capacity (CEC) increased by 13%. Concerning the variant with fertilizers (N4PK), the total sorption capacity (CEC) increased by 7% in comparison to non-fertilized control. There were not determined significant differences in monitored parameters in subsuďace layer of the soil profile. This can be attributed to the nature of the soil forming process and genetic characteristics of a representative soil.
