Opis:: The author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

Opis:: Natural variability of pseudogley forest soils in the Białowieża National Park was characterised on the basis of five soil exposures. Two of them were located in a water-logged site, one in a mound one in a patch with dominance of deciduous trees, and one in a spruce biogrup. It was found that pseudogley soils of a natural moist deciduous forest show additional differentiation in the form of characteristic micromosaics. There is a pronounced impact of the species structure in a treestand, uprooted trees and hoofed mammals on the properties of the soil cover. Changes resulting from the above biotic factory were observed in all the analysed physical, physico-chemical and chemical soil parameters.
