Lanthanides are attracting increasing interest due to their technological importance and potential ecotoxicity. Knowledge of lanthanides in Polish soils is very poor, and a question arises whether the soils of former metal ore mining sites are enriched by these elements. Therefore, concentrations of six crucial lanthanides – La, Ce, Pr, Nd, Sm, and Gd – were determined in 92 soil samples collected...
The missing data on bulk density make impossible the calculations of soil water retention, organic carbon pools and evaluation of the numerical indices of soil and forest habitat fertility and potential productivity. A common reason of skipping of bulk density measurement is the high content of rock fragments in soil, in particular in the subsoil layers, that may hamper the collection of samples with...
Five soils differently contaminated by emissions from copper smelters were treated with the organic materials lignite, compost, and sewage sludge. The concentrations of Cu, Zn, and Pb in soil solutions were measured after different incubation times within 30 days. Speciation of metals in soil solution was determined via modeling with Visual MinteQ. Soil amendment with all organic materials led to...
Soil solutions were collected from soils contaminated differently by the emissions from a copper smelter and incubated with beech litter. Five times in 30 days of incubation, soil solutions were acquired with MacroRhizon samplers and examined using the chemometric approach and two ecotoxicological assays: Microtox with Vibrio fischeri bacteria and Phytotoxkit with Sinapis alba seeds. Copper speciation...
Both the international ISO standard and modern soil classifi cations and databases require soil pH measurement at a 1:5 soil:solution ratio, while the ratio 1:2.5 is still the most commonly used in Poland and other European countries. The transformation of laboratory practices is necessary, but it is also necessary to establish and validate a reliable procedure for converting soil pH at soil:solution...
The paper focuses on ultrasonic method used for cleaning of root material collected from a pot experiment. In the experiment, red fescue was grown on differently contaminated soils amended with organic additions. Determined were total concentrations of Cu and Zn in root material pre-pared for analysis by hand washing and the use of ultrasonic bath. The results indicate significant differences between...
W artykule zawarto zagadnienia związane z postępem prac rekultywacyjnych obszarów poeksploatacyjnych odkrywki węgla brunatnego „Adamów”. Przeprowadzono ocenę terenów zrekultywowanych, pod kątem wartości przyrodniczych oraz stopnia wkomponowania w istniejący krajobraz. Skategoryzowano stan sukcesji poszczególnych typów siedlisk. Zaprezentowano etapy oraz cechy kształtowana nowych, wartościowych form...
Chemical properties and fertility of soils were compared under spruce, mixed and beech stands in four types of forest habitat (mountain broadleaf forest, mountain mixed broadleaf forest, mountain mixed coniferous forest and mountain coniferous forest) in 373 sites of forest monitoring in the Stołowe Mountains National Park, SW Poland. Soils under the spruce stands had higher organic carbon pools in...
The study presents quantitative analysis of the humus horizons of mountain soils in the Stołowe Mountains (south−western Poland) diverse in terms of parent material and stand species structure. The study included moder ectohumus horizons (Ol − raw humus, Ofh − detritus humus) and Ah mineral humus horizon in brown soils developed on granite, siltstone and permian sandstone. The examined profiles was...
Study presents physical−chemical and chemical properties of humic acids in ectohumus (Ol and Ofh) and mineral humus (A) horizons of brown soils developed on granite, siltstone and permian sandstone. The examined profiles were located in forest habitat representing the fresh mountain forest under spruce and beech stands growing on moder type of forest humus.
Deep dystric Cambisols developed on the homogenous regoliths of granite in the Stołowe Mountains National Park (SW Poland). In general, the soils have a texture of gravelly sandy loam, apparently silty, the strong acid reaction and the base saturation below 30% throughout the profile (oligotrophic variant). Only the soils developed in lower parts of slopes have a base saturation up to 40−50% or more...
W przeprowadzonym doświadczeniu badano wpływ różnych rodzajów substancji organicznej na rozpuszczalność i fitoprzyswajalność miedzi w 5 glebach pochodzących z rejonu hut miedzi Gło¬gów i Legnica oraz składowiska osadów poflotacyjnych Żelazny Most. Badania przeprowadzo¬no w warunkach doświadczenia wazonowego, z sałatą siewną Lactuca sativa, odmiany Królowa Majowych, jako rośliną testową. Do gleb wprowadzono...
This paper describes the fractional composition of humus substances and physico-chemical properties of ectohumus horizons in forest soils (Haplic Cambisols (Distric) and Albic Podzols) developed from various parent materials and in various forest sites: mountain mixed forest witch beech tree, spruce forest witch spruce monoculture, mountain mixed forest witch beech, sycamore maple and larch and mountain...
