The impact of long-term cultivation of spruce stands and the influence of acid atmospheric pollutants on the development of forest soils was studied in a vertical transect in the Working-plan area Forests (Spisska Nova Ves, Slovak Republic). Statistical analyses showed that the mean values of active and exchange reactions found in loamy sand Podzols were significantly lower than those found in sandy loam and loam Cambisols. The active reaction in A horizons of Cambisols was already shifted below the value 3.9, i.e. in the span of oligotrophic order of geobiocoens. The process of podzolization is reversible, because the albic horizons of Podzols were not still formed. The loamy sand Podzols occurring in the upper part of the transect are rich in skeleton (80-90 %) and their maximum water capacity represents only 60-80 mm of water column (28-58 % of water capacity in studied Cambisols).
