The studies on contents and profile distribution of total phosphorus and its fractions extracted according to the procedure of Hedley et al. [1982] in a modification of O’Halloran et al. [1987] in forest Brunic Arenosols of post−fire areas in the Rudy Raciborskie Forest District (S Poland) were undertaken. Five soil profiles developed from fluvioglacial sandy deposits of the Oder Glaciation were described...
The paper presents results of the studies on Cu, Mn and Zn content in forest soils of northern and central Poland covered by intensive monitoring. The investigated stands (Białowieża, Chojnów, Gdańsk, Krotoszyn, Krucz, Łąck, Strzałowo, Suwałki) cover various soil reference groups, including Brunic Arenosols, Cambisols and Stagnosols, developed from Quaternary deposits of different origin – glacial...
The studies focused on phosphorus speciation in Gleyic Podzols of the supra−flood terrace of the Słupia River, south from Słupsk (N Poland). The content and within profile distribution of phosphorus were considered in the context of parent material origin and the influence of podsolization, high groundwater level, forest vegetation and vicinity of the town. Four soil profiles representing Gleyic Albic...
The following research on plant litterfall mass, dynamics, structure and chemistry was conducted from 2012 to 2014, on a 40- to 86-year-old stand of black alder (Alnus glutinosa) growing in a headwater area of the upper part of the valley of the Kamienna Creek (Middle Pomerania). Litterfall was collected every month with 20 circular traps, dried untill constant weight, divided into fractions, weighed...
The paper concerns changes of chemical composition of water in headwater streams in the valley of the Kamienna, left bank tributary of the Słupia River (54°19′N; 17°10′E). Water samples were collected in 2012 from three streams, in their upper, middle and lower course every month. Analysis included water temperature, pH, conductivity, and the content of dissolved oxygen, HCO3– , K+, Na+, Ca2+, Mg2+,...
The paper presents the result of the studies on the properties of soil organic matter in Sapric Histosols associated with mid−forest spring niches in the valley of the Kamienna Creek, left bank tributary of the Słupia River (northern Poland). We sampled five soil profiles at the depth of every 10 cm until the mineral bed was reached. We analyzed degree of peat mass decomposition, reaction and the...
The aim of the study was to recognize the vertical variability in the content of different forms of carbon and nitrogen in Histosols of a forest spring niche located in the upper course of the Kamienna Creek (the Słupia River catchment). Soil samples were taken from three profiles and analyzed with standard methods used in the soil science. Analyses included the degree of peat mass decomposition,...
Buffering properties, their spatial and vertical variability and factors influencing them, were studied in the soils of mill-pond basin in the valley of the Jarosławianka Creek (northern Poland). Layered, mud-alluvial deposits were accumulated on the bed of buried bog soils from 1351 until the mid of the twentieeth century, and during the last few decades, along the creek channel, were covered by...
The studies on iron and aluminium forms and soil forming processes quantification in Chernozems were conducted in two localities in Western Slovakia. Two soil pits were done in a complex of arable Haplic Chernozems in Krakovany and two soil pits representing arable and forest Cambic Chernozems were done in Báb. The soils were sampled every 10 cm and analysed using standard methods. Based on analytical...
Comparative studies on the content and profile distribution patterns of phosphorus fractions in arable and forest Cambic Chernozems were conducted near the village Báb (western Slovakia). Soil samples were collected from every 10 cm and analyzed using standard procedures in soil science. Long term differences in the type of the studied soils usage were reflected in their physical and chemical properties...
The content and profile distribution patterns of Cu, Ni and Zn in Histosols of headwater peatlands were studied in the valley of Kamienna Creek – left bank tributary of Słupia River. The soils were sampled every 10 cm up to mineral bed. The content of metals was analyzed with microwave plasma atomic emission spectrometry method after digestion of samples in a mixture of concentrated HNO3 and 30% H2O2...
The aim of the study was an assessment of Słupsk urban environmental contamination with copper and nickel based on concentrations of these metals in Scots pine (Pinus sylvestris L.) needles and associated soils. The contents of Cu and Ni were analyzed in 1- and 2-years-old needles and in 0-20 cm and 40-60 cm layers of soils. Plant and soil samples were collected in 2010 form 25 stands of different...
