Opis:
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 and sampled 21 years after the fire occurrence and analyzed using standard procedures. Total content of the element was among typical for Brunic Arenosols of Poland, ranging from 683.1 to 880.4 mg/kg in Ofh horizons, from 154.2 to 566.5 mg/kg in mineral horizons affected by soil−forming processes and from 115.5 to 384.2 mg/kg in parent material. The content of distinguished phosphorus fractions varied, reflecting the effect of environmental factors and brunification soil−forming process. Residual fraction predominated in parent material, organic in O and most of A−horizons and bounded to sesquioxides in B−horizons. The observed proportions between residual fraction and sum of the remaining fractions were typical for soils of old−glacial areas, reflecting considerable degree of mineral substrate weathering. An effect of fire was not clear due to the lack of a reference soil. However, the studied soils showed some specific features, that can be explained by the influence of fire. Low content of fraction bounded to calcium and apatites is the first and elevated concentration of fraction bounded to sesquioxides in parent material is the other one. Profile distribution patterns of mentioned above fractions suggest leaching of phosphorus labile forms and their stabilization in deeper parts of the studied soils. This process could be initialized or accelerated by fire. Finally, it can be concluded, that studied properties of the contemporary soils are stronger influenced by pine forest vegetation than by fire before 21 years.

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.
