ABSTRACT
The aim of this study was to determine the dehydrogenases and urease activity in forest luvisols of various fertility and plant community on them. It attempts to find out whether the conditions of occurrence of the lessivage process relation exist between soil biological activity expressed as enzymatic activity and their physico-chemical properties. Dehydrogenases and urease activity varied across the subtypes of luvisols and proved to be a better parameter differentiating the particular subtypes of soils compared to the physico-chemical properties. The lower enzymatic activity of hypocambic luvisols made of boulder clay, compared with the activity of enzymes in the haplic luvisols, implies a significant effect of particle size on the biological activity of forest soils, shown previously in bibliography. Studies confirm that the enzymatic activity reflects initial imperceptible changes in the horizon of humus as a result of the impact of vegetation.
Key words: enzymatic activity, dehydrogenases, urease, forest soil, luvisols.
