W pracy scharakteryzowano warunki glebowe trzech kompleksów łąkowych położonych w Puszczy Piskiej. Celem pracy jest dokumentacja środowiska przyrodniczego jako podstawy do śledzenia zmian wywołanych rolniczym użytkowaniem. Dąje ona również naukowe podstawy do zagospodarowania i nawożenia łąk. Na badanych łąkach występują pobagienne gleby hydrogeniczne, Gleby torfowo-murszowe wykształciły się na złądowiałych zbiornikach wodnych pochodzenia wytopiskowego. W ich profilach występują osady limniczne (gytia wapienna i organiczna). Gleby mineralno-murszowe i murszowate właściwe (10-20% materii organicznej) wykształciły się w wyniku murszenia płytkich torfów olesowych załegąjących najczęściej bezpośrednio na podłożu piaszczystym. Gleby murszaste (próchniczne gleby o zawartości 3-10% materii organicznej) uformowały się najczęściej w wyniku murszenia torfiny - specyficznej ściółki wilgotnych lasów z udziałem olszy czarnej i świerka pospolitego. Podkreślono duży wpływ wcześniejszą wegetacji olszy na właściwości badanych gleb. Scharakteryzowano roślinność łąk w nawiązaniu do wydzielonych jednostek systematycznych gleb. Rozmieszczenie gleb przedstawiono na mapach. Podstawowe właściwości gleb, w tym również fizyczne i retencyjne, zestawiono w tabelach. Przeanalizowano także wpływ zawartości materii organicznej na właściwości retencyjne gleb.

The paper presents the soil conditions of three meadow complexes located in the Pisz Primeval Forest. The aim of the paper was to provide documentation concerning the natural environment, which will then serve as a basis for observing changes caused by its agricultural use. Moreover, it gives a scientific basis for meadow management and fertilization. Post-boggy hydrogenic soils are present in the meadows studied. Peat-moorsh soils are found in melt-out water bodies, converted into land. Their profiles include limnic deposits (calcareous and detritus gyttja). Mineral-moorsh soils and proper moorshy ones (10-20% of organic matter) came into being as a result of processes taking place in low alder-wood peats, most often located directly on sandy ground. Moorshous soils (i.e. humous soils with 3-10% organic matter content) were generally formed due to decomposition of a special kind of litter characteristic of wet forests with common alder and Norway spruce trees. A significant influence of prior vegetation of alder trees on the properties of soils investigated is emphasized in the paper. Meadow vegetation is also described within separate soil survey mapping units. Soil distribution is presented on maps. General properties of soils, including physical and retentive ones, are to be found in tables. The effect of organic matter content on retentive properties of soils is analyzed as well.

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.

The Macroregion of the Mazurian Lake District and the adjoining mesoregion of the Sępopol Plain were formed during Baltic glaciation and in the post-glacial period. The existing habitat differentiation, especially large variations in the soil cover, is divided into three distinct landscape zones. The northern areas of the district are typical heavy and very heavy soils, composed of tight clays and loams, represented by brown soils and black earths. They contribute to the ecosystem stability. Hydrogenic soils occupy only a small area. Agricultural production, when carried out correctly, should not threaten the habitat and should be in harmony with the area in question. The central, moraine area of the Mazurian Lake District, with unique natural qualities, is comprised of different soil forms and various soil covers. Brown and lessive soils are dominant among mineral soils. Deluvial soils are common, which is a warning sign on the danger of erosion. Contribution of hydrogenic soils is clearly seen. Protection of these soils, as well as re-naturalisation of the selected areas, is becoming vital. This area badly requires ecological farming. Light and very light soils, mainly rusty and podzo! soils, accompanied by large areas of sensitive for transformation hydrogenic, muck, and mucky soils occur in the southern part of the district, in the area of outwash plains. Outwash plains call for complex solutions to improve the quality of their mineral soils, as well as utilisation and protection of hydrogenic soils.
