ln order to investigate the influence of different air pollution levels on the degree of forest soil acidification and forest stability (APOS project), four experimental plots were established in Poland. Characterization of soil properties which were necessary for interpretation of acid deposition in the soil and in the trees are presented in the paper. Soil samples were taken from 5 soil piths per plot. Each pedon was described and sampled at genetic horizons to a depth of 2.0 meter. Volumetric samples for physical analyses were sampled from the same horizons. Each soil sample was analysed for a particle size distribution, pH, exchangeable cations (Ca, Mg, K, Na, Mn, Fe, AI, H), and the total element contents (C, N, S). Podzol soils from Augustow and Lobez plots have got very similar physical and chemical properties. Brown soil from Szklarska Poreba has finer texture and contains more C, N, and exchangeable basic cations than podzol soils.
