ABSTRACT
The impact of long-termed cultivation of spruce stands and of acid atmospheric pollutants was studied on vertical transect in the Working-plan area Forests of city Spišská Nová Ves. Statistical analyses showed that the mean values of active and exchange reactions found in loamy sand Podzols were significantly lower compared with sandy loam to loam Cambisols. The results showed, that the active reaction in A horizons of Cambisols was already shifted below 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 upper part of transect are reach in skeleton (80--90%) and their maximum water capacity represents only 60--80mm of water column (28--58% of water capacity in studied Cambisols).
