Opis:
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 Ortsteinic Podzols and Umbric Gleyic Albic Ortsteinic Podzols developed from aeolian sand were described. Samples were taken from distinguished horizons and physical and chemical properties were analyzed using standard procedures. Sequential extraction of phosphorus was performed by the method of Hedley et al. [1982]. The soils were characterized by strong acidic reaction, high abundance of organic matter and low degree of mineral substrates weathering. Profile distribution of free iron oxides was typical for Podzols. The content of total phosphorus in parent materials varied from 142.2 to 365.0 mg/kg, whereas in solum from 103.0 to 1035.6 mg/kg, reaching the highest values in B horizons and the lowest in E horizons. The noted concentration was high as compared to the soils of the same type within the area of Poland. Increased phosphorus concentration can be caused by the influence of high groundwater level and vicinity of the town, as a source of biogenic substances. The predominance of residual fraction in solum evidences young age of the studied soils, which is confirmed also by the results of thermoluminescence dating. Profile distribution patterns of total phosphorus and its fractions reflects the influence of groundwater, vegetation and soil−forming processes in turnover of this element. The results confirm also strong linkage between iron and phosphorus in the soils.

Opis:
The aim of the study was to assess the influence of lithological and pedogenic factors in the shaping of Cu, Ni and Zn distribution patterns in the profiles of Brunic Arenosols and Gleyic Podzols of the lower supra-flood terrace of the Słupia River, which is located outside the range of significant anthropogenic sources of pollution with these metals. The contents of the investigated metals were analyzed in aqua regia extracts of samples collected from three profiles of Brunic Arenosols, composed of river sands, and three profiles of Gleyic Podzols, composed of river sands transformed by eolian processes. In general, river sands contained higher amounts of Ni and Zn (2.6–6.9 mg·kg-1 Ni; 10.3–16.2 mg·kg-1 Zn) compared to eolian sands (1.2–2.4 mg·kg-1 Ni; 3.3–17.3 mg·kg-1), while the content of copper tended to be higher in eolian sands (1.3–1.9 mg·kg-1) than river sands (0.1–1.5 mg·kg-1). The observed differences between the two types of sand are due to the loss of fine granulometric fractions and various minerals during eolian processes. Higher concentrations of the investigated metals in soil solum as compared to parent material are due to their uptake from deeper parts of the soil by roots and subsequent return to the soil surface by litter fall. Therefore, the highest concentrations of Cu, Ni and Zn were observed in ectohumus. In the mineral component of the soil, the highest concentrations were observed in organic matter-rich A and B horizons, which indicate close interactions between heavy metals, humic substances and iron oxides. The vertical distribution of the investigated metals in the profiles of Gleyic Podzols indicates their leaching during podzolization. The observed contents of Cu, Ni and Zn, both in Brunic Arenosols and Gleyic Podzols, were lower than the geochemical background, which confirms that anthropogenic contamination of the studied area with these metals is marginal.
