The object of the study is to compare chemical properties of forest sites being limed in 2004 with the ones in their vicinity, which were not limed. The forests in the investigated area are supposed to have been affected by air pollution. Three soil horizons were sampled. The value of pH, amount of organic material, total soil nitrogen, oxidizable soil carbon and extractable contents of chosen elements (P, K, Ca, Al, Mn and Fe) were determined in the forest floor horizon. The same characteristic supplemented by values of plant accessible elements (P, K, Ca, Mg, Al, Mn, Fe, S) and the investigation of soil sorption complex ((Al + H)+, K+, Ca2+, Mg2+, Mn2+, Al3+, Fe3+, CEC, BS) were carried out in the organomineral and mineral horizons. The investigation of contents of chosen elements (N, P, K, Ca, Mg, Mn, Al, Fe, B, S) in the Norway spruce needles was done to evaluate the difference in the nutritional level on the compared sites. For this purpose, the needles of current and previous year were investigated. The statistical processing focused on the characteristics, which are supposed to have been induced by forest liming performed ten years ago. This study reveals that soils of the limed sites were richer and healthier than of the unlimed ones and that the trees on the limed sites were in better nutritional conditions.
