    Opis:
    This study was carried out in the Słowiński National Park (SNP, northern Poland) in 15 Scots pine forest stands. The research objective was to analyze the content of macro− and microelements in Pleurozium schreberi and Hylocomium splendens and to compare accumulation properties of these mosses. The examined parameters characterized by diverse composition, which depended on the mosses species and location of the study plot. The nitrogen was determined by Kiejdahl method, and the phosphorus by the molybdate method. The content of K, Mg, Ca, Zn, Cu, Ni, Mn, and Fe was assessed by atomic absorption spectrometry after mineralization in the mixture of 65% HNO3 and 30% H2O2. The content of microelements in mosses was low and indicated low abundance of forest ecosystems in the SNP as to basic nutritional components. The highest average amount of nitrogen, phosphorus, iron, manganese and copper were found in H. splendens, while potassium, magnesium, calcium, zinc and nickel in P. schreiberi. The content of zinc, nickel, copper, manganese and iron in both species were within the limits of permissible values characteristic for the plants of the unpolluted areas. Relation among the determined macro− and microelements in both species constituted the following decreasing series: N>Ca>Mg>P>K>Fe>Mn>Zn>Ni>Cu (H. splendens) and N>Ca>Mg>K>P>Fe>Mn>Zn>Ni>Cu (P. schreberi). Mann−Whitney test indicated the significance of the differences in the content of N (p<0.001), K (p<0.001) and Cu (p<0.01) between in P. schreberi and H. splendens. The mosses accumulated from 641.7 to 689.3 mmolc/kg of all the analyzed components, and the lower sum of the accumulated macro− and microelements was found for P. schreberi. Accumulation differences in the properties of the examined species of mosses primarily result from the varying demand for individual components. Relatively high participation of Mn and Fe in the sum of the measured components in both species of moss can be the evidence of excessive uptake of these elements from the soil with heavily acidic reaction of the organic and humus levels of the soils in the SNP.

    Opis:
    The paper presents the analysis of the macro− and microelements content in the leaves, stems and roots of Vaccinium myrtillus and Vaccinium vitis−idaea as well as in the surface genetic horizons of the soils of the Słowiński National Park (SNP). The cumulative properties and translocation coefficients were characterized as well as translocation coefficients of nutritional components in bilberry sprouts. The nitrogen was determined by Kjeldahl's method. The contents of K, Mg, Ca, Zn, Cu, Mn, and Fe by atomic absorption spectrometry after digestion in the mixture of 65% HNO3 and 30% H2O2. Organic and humus horizons of the tested soils represented the acidic reaction and diversified quantity of organic matter. The content of basic macro components in the soils of the SNP was very low. Concentration of Zn, Cu, Mn and Fe in the soils remained within the limits of geochemical background without showing any pollution with these elements. Chemical composition of bilberry sprouts was diversified depending on species, fragment of the sprout and the study plot. Nitrogen content in leaves and stems of V. myrtillus was much higher than in the case of V. vitis−idaea. The roots of both species of bilberries accumulated similar quantities of N, which is indicated by the values of the bioaccumulation coefficient and the lack of statistical diversity. All analyzed macro− and microcomponents were accumulated in the highest quantity in the leaves and stems of V. myrtillus, which represented, without any doubt, higher demand of this species for nutritional components. The roots of V. vitis−idaea accumulated higher quantities of Mg, Ca and Zn, while the stems of bilberry accumulated twice as much manganese (1198.3 mg/kg) than the stems of cowberry (561.2 mg/kg). The test results show excessive accumulation of Mn by sprouts of V. myrtillus. In the case of the examined species, the highest mobility was characteristic for N and K (in the relationship leaves/stems) and Ca, Mg, Mn, K and Zn (in the relationship stems/roots). Fe and Cu were characterized by the lowest mobility in bilberry tissues. Significant differences in the content of N (p<0.001) and Mg (p<0.001) in leaves and stems, K (p<0.001), Cu (p<0.05) and Fe (p<0.01) in leaves, Zn (p<0.05) and Mn (p<0.001) in stems were found. Differences in accumulation of macro− and microcomponents in the roots seemed not to be significant.

    Opis:
    The paper presents the assessment of growth parameters and the impact of pure stands of Scots pine, European larch, common birch and black alder on the reaction and chemical properties of the initial soils developed on the reclaimed sand pit ‘Szczakowa’ (southern Poland). Pine, larch and birch stands were characterized by good growth parameters, which confirms high adaptability of these species to post−mining sites. The black alder was characterized by worse growth parameters. The organic horizon (Olf) under conifers (pine and larch) were characterized by higher mass and lower pH than under deciduous species (birch and larch). The alder litter contained more N, K and Mg compared to other tree species. In the Ain initial horizon, the modifying effect of tree species was only detected in the case of black alder by higher exchange acidity and cation exchange capacity (CEC), higher content of soil organic carbon (SOC) and total N, and a lower C:N ratio, compared to soils under influence of other species. The research confirms that the selection of species composition for afforestation is an important factor affecting the soil−forming processes on reclaimed sand pit. In particular, the alder was characterized by beneficial effects on soil properties, which confirms its usefulness as a phytomeliorative species.
