The studies were carried out on a drained Łokieć Peatland. They concerned physical (bulk density, ash content, porosity) and water (potential and effective useful retention, static percolation, transitory reserves) properties of peat-moorsh soils. Permeability and moisture formation in the rhizosphere of soils under meadows and forests were the other concerns of this study. Drained peat-moorsh soils were found to be best protected from degradation when utilized as meadows; forestry unfavorably affected these soils. In the latter case, changes of the peat mass structure were more profound than under meadows. An upper soil layer was loosen as demonstrated by enhanced soil porosity and a smaller bulk density. Permeability of the rhizosphere under the birch wood was much greater than under meadows. The most advanced drying and depletion of ground water reserves (water easily available to plants) was found in the peat-moorsh soil under birch wood; it was much smaller under meadow vegetation.
