The differentiation of the properties of soils at the level of pedons constitutes one of the most essential elements of the functional-structural analysis of the ecosystems. The purpose of the studies presented in this paper was to assess the spatial variability of the soil cover as conditioned by the micro-habitat differentiation and expressed through the variability of thickness of the genetic horizons for individual pedons, as well as spatial differences in acidity, moisture, conductivity, and organic carbon content. The studies were conducted on podzolic soils covered with forest vegetation. The results of studies carried out and described here indicate an influence of the local topo-habitat conditions on the spatial variability of soil properties. the following results can be drawn on the basis of the results obtained: 1) within the organic horizon the highest spatial differentiation of the properties considered was observed in the soils of Finland and Norway, while within the humus and enrichment horizons it was greater in the soils of the Polish part of the study area; 2) an exception to the above regularity is constituted by moisture; the highest spatial differentiation at this factor within all the genetic horizons was always observed in the soils characterised by its highest values; 3) spatial differentiation of the properties analysed is greater within the organic and humus horizons than in the enrichment horizon; 4) the biggest differences between the particular variants of the experiment, implemented during the four years of study, were displayed by: a) within the organic layer - the pedons of the northern and central parts of the study area, fromm Norway to Latvia, b) within the humus layer - the marginal pedons of FN1 and PL3 as well as the pedons of the central part of the study area - from Lithuania and Latvia, c) within the enrichment layer - the pedons of the Polish part of the study area; 5)interdependence was observed between the length of the micro-transects and the variability of the soil properties analysed; and 6) the strongest interrelation between the analysed properties were registered for the moisture - organic carbon content and moisture - conductivity.
