Abstract
<\/strong>The Masurian Lake Biosphere Reserve was created in 2017 by way of renomination of the previous Lake \u0141uknajno Biosphere Reserve, existing since 1977. After enlargement, the reserve covers 58 693.71 ha, including 6 786.90 ha of the core area. Currently, beside Lake \u0141uknajno, it covers a significant part of the Masurian Landscape Park. The study covers immediate surroundings of \u0141uknajno lake. The soil cover here has been largely affected by the water regime, i.e. ground water level. Eleven soil profiles were described, and the following analyses were carried out in the collected samples: soil texture (in mineral soil materials), CaCO3<\/sub> content, soil reaction, organic carbon and total nitrogen content, specific and bulk density, and organic carbon stock. According to the Polish Soil Classification (2019), 6 soil profiles were classified within the order of organic soils (4 soil profiles as peat soils, one as murshic soil and one as gyttja soil). Soils occurring farther from the contemporary border of the \u0141uknajno lake were classified as: mineral-peaty gleysol, gleyic chernozemic colluvial soil, humic regosol, typical semimurshic soil and typical postmurshic soil. According to the WRB classification (2022), 5 profiles were classified as Histosols (Drainic Sapric Histosols, Murshic Fibric Histosols, Murshic Sapric Histosols, Rheic Histosols) and 6 soil profiles (adjacent to organic soils) as: Calcaric Regosols, Eutric Solinovic Arenosols, Eutric Gleysols, Eutric Arenosols, and Haplic Umbrisols. The properties of soils were related to the high content of calcium carbonate which had been leached from the catchment area and accumulated in the basin of Lake \u0141uknajno in the form of thick layers of calcareous gyttja. Currently, the basin of the lake is almost completely filled with gyttja, and on the surface the chara meadows have developed. For the soils studied, high organic carbon stock was characteristic, and ranged from 74.4 to 111.9 kg Corg<\/sub> per m2<\/sup> for the depth of up to 150 cm in organic soils. The soils adjacent to organic ones in the landscape also had significant organic carbon stock (17.4\u201332.1 kg\/m2<\/sup>) which was associated with semihydrogenic water conditions.<\/p>\n
