The study deals with evaluation of a liming experiment carried out in spruce stands situated near Bílý Kříž in Moravian-Silesian Beskydy Mts. at an altitude of 908 m. Soil type was humo-ferric podzol with mor-moder humus form and low content of nutrients. Soil properties and soil solution composition from two research plots with Picea abies [L.] Karst. monoculture aged 28 in 2006 were compared. One of the plots was limed by dolomitic limestone at a total dose of 9 t ha-1 in the 80s of the 20th century the second plot was a not-limed control. Sampling of sub-surface seepage water was carried out in fortnight intervals on the both plots during 2001–2006. Statistically significant differences between the limed and control plot were found in soil solution concentrations of Ca2+, Mg2+, Na+, K+, NH4+, HPO42-, SO42-, dissolved organic carbon (DOC) and pH. Significant differences were not observed between the plots in NO3- concentrations. Soil samples taken from the both plots in 2003 were analyzed and the results have shown that changes induced by liming could be detected even after 16 year after the last liming event. Increased pH values in the entire soil profile, and changes in the composition of soil sorption complex and increased base saturation in the forest floor horizons were found on the limed plot.
