The paper demonstrated results about the investigations of Mn release phenomenon from peat soils into the soil solution. Laboratory experiment lasted 443 days, and was performed at 18ºC, under flooded conditions on three peatland samples (Moszne, Garbatówka and Orłowskie). The highest Mn concentration (0.07 mg kg-1) was noted in Orłowskie peatland, whereas the lowest (0.022 mg kg-1) in the soil taken from Garbatówka. It was indicated, that the ability of Mn release into the soil solution during incubation time decreased with the depth of the soil profiles (except of Moszne peatland, where maximum of Mn concentration at >50 cm was registered), and increased with drop of redox potential.
