The aim of this work was to compile characteristics of some selected physical, physico-chemical and chemical properties of the reclaimed hydrogenic soils in the meadow part of the Przedmoście bog in the context of new forming plant communities. Melioration work conducted in this area before the Second World War ended peat accumulation processes. Consequently, drying peat began to disintegrate and mineralise. Analyses of floral lists proved that the existing vegetation replaced the original bog plant communities, which flourished in this area in the past. Descriptions of profiles point to the existence of mixed formations (gyttja, peat) often containing high quantities of CaCO3. Peat formations present in the profiles are usually at the advanced degree of decomposition (H > 7) and contain substantial quantities of ash. This high degree of ash content and bulk density results in strong compaction and muddy soil horizons. A low coefficient of C/N showed intense mineralization of organic matter in the upper soil horizons.
