Minerálne zloženie kalu je zastúpené kremeňom, chloritmi, muskovitom, karbonátmi (siderit, dolomit) a pyritom, ktorého celkový obsah nepresahuje 5 hmotnostných percent (Lintnerová et al., 2011), (Lintnerová a Mangová, 2012). Napriek zvetrávaniu pyritu a značnej acidifikácii, ktorá sa prejavovala pred a po rekultivácii, sa na po niekoľkých rokoch odkalisku začala rozvíjať vegetácia. Povrch je pokrytý prevažne náletovou trávnatou vegetáciou, miestami súvislejšou opadavkou z ihličnatých stromov a machmi. Cieľom tejto práce je posúdiť stav pôdotvorného procesu využitím získaných poznatkov o chemických a fyzikálno-morfologických parametroch antrozeme.

The clay minerals were standards from the Source Clay Minerals Repository (University of Missouri, Columbia, USA). The persistence of water repellency was estimated with the water drop penetration time (WDPT) test. After wetting, water repellency disappeared in all the samples. During the drying phase, water repellency re-appeared in all samples (untreated and calcite-treated) as the water content decreased below 1%. Repellency did, however, not reach pre-wetting levels. The effect of calcite addition on water repellency depended on the amount of calcite addition. An addition of 1% and 15% calcite resulted in decrease in WDPT in the treatment without the wetting and drying cycle before the heating at 50°C. The effect of clay contents on water repellency differed strongly among the four clay minerals. Kaolinite and Namontmorillonite reduced WDPT significantly, while Ca-montmorillonite and illite were less effective or caused even increase in WDPT. The heating at 50°C was used to simulate the effects of hot dry spells on water repellency.

However, exampling mercury phytotoxicity for barley (Hordeum vulgare) this paper highlights unsuitability of this experimental approach. Mercury(II) in spiked soils is extremely bioavailable, and there experimentally determined bioaccumulation is significantly higher compared to reported mercury bioaccumulation efficiency from soils collected from mercury-polluted areas. Our results indicate this is not affected by soil sorption capacity, thus soil ageing and formation of more stable mercuric complexes with soil fractions is necessary for reasonable metal phytotoxicity assessments.

Calculated separation yields for applied separation techniques were in many cases comparable with soil-plant transfer recovery values for studied plant species. Distribution of Hg in roots of studied root vegetables showed the tendency of increasing amount of Hg from basal towards terminal part of root.

The pH value of both antimony-free and antimony supplemented culture media declined in the first five days to extremely acidic region (approximately pH 2) and did not change during the rest of cultivation period. There were no statistically significant, microbially mediated changes in pH of broth media supplemented with Sb(III) when compared to antimony-free control. While the biomass yield of antimony supplemented culture media (upto 100 mg.L-1) during the exponential growth phase was identical to the antimony-free control, antimonyl tartrate however, had beneficial effect on fungal growth during the stationary growth phase. According to antimony accumulation results, A. niger strain efficiently reduced the uptake and enhanced the efflux of antimony during the first week of cultivation though later uptake of antimony was enhanced. The results indicate a relationship between the amount of antimon...

Samples (0-20 cm) were collected from forest soils exhibiting some degree of water repellency. Persistence of SWR was measured by commonly used water drop penetration time (WDPT) test and the severity of SWR by molarity of an ethanol droplet (MED) test A heating experiment was designed in order to simulate conditions that normally occur in nature and are favourable for the change of SWR in soils. From the results it follows that heating at 50 °C for the first three days caused in most soils a gradual decrease in MED values. Initial MED values were re-established only after soil heating at 150 °C. This means that input of thermal energy was necessary to re-organize organic molecules causing SWR. In terms of comparison the MED v...

(2015): Identifying the origin of soil water repellency at regional level using multiple soil characteristics: The White Carpathians and Myjavska pahorkatina Upland case study. Soil & Water Res., 10: 78-89. This paper evaluates the relationship between water repellency and multiple characteristics of topsoil samples belonging to seven Reference Soil Groups, taken from the area of the White Carpathians and the Myjavska pahorkatina Upland. In order to quantify water repellency, the Water Drop Penetration Time test and the Molarity of an Ethanol Droplet test were performed on 210 soil samples. The water repellency data were confronted with a number of categorical and numerical soil variables. It was observed that the particular land-use type and the nature of soil parent material, both are related towards detected water repellency of soil samples. All samples taken from the agricultural (tilled) and grassland soils were wettable. On the contrary, all samples which exhibited water repellency, belonged to the group of forest soils, although, not all forest soils were water repellent. Samples which showed considerable repellency were soils developed either on consolidated sedimentary rocks (sandstones, limestone-dolomitic rocks, flysch) or unconsolidated sediments of aeolic or polygenetic origin. On the other hand, the great majority of soils developed on recent alluvial deposits were clearly wettable. Correlation and regression analyses showed that susceptibility of forest topsoil to exhibit water repellency generally increases with increasing sand and organic carbon contents, and with a simultaneous decrease of soil pH value. An interesting observation came out regarding CaCO 3 and water repellency relation. Although certain soils with higher CaCO 3 exhibited water repellency (Rendzic Leptosols and Cambisols), all soils that developed on loose sediments and contained CaCO 3 were wettable.

When compared with control, the presence of selenite influenced the pH values of culture media, while the weight of biomass was not changed significantly. The concentration of selenite in culture media decreased rapidly on the 10th day of cultivation from initial concentration 19 and 27 mg.L -1 to 1.07 and 1.26 mg.L -1, respectively. However, the concentration of total selenium did not change during the 25-day cultivation significantly. While the accumulation of selenium on the 25th day of cultivation was negligible, almost all of uptaken selenium by fungus was transformed into volatile derivatives (up to 21% of initial selenite content in culture media). The removal of selenite from its aqueous solution by fungal biomass of A. niger is rapid, since the equilibrium was achieved after 20 min. However, ...

In the region were an occurrence and historical view of the erosion processes were already published we turn our attention to aggregate stability of materials in which gullies are formed. For aggregate stability measurements we used rainfall simulator method. Aggregate fraction 0.25 - 4 mm was placed (4 g) into a 0.25 mm sieve and exposed to 30 mm of an artificial rainfall with known energy (270 J/m2). Mean value of three replicate measurements was calculated for each sample. In soil profiles where the gullies occur, the highest aggregate stability was found in surface humus horizons (mostly >60%). Considerable less aggregate stability was determined in underlying marls (frequently <25%). Gradually increasing aggregate stability in newly formed humus horizons was found on the slopes of gullies. Distinct difference in aggregate stability in topsoils compared to the underlying marl material can be considered as an important factor of gully formation in this region. Man-made disturbance of resistible surface soil horizons often starts a very strong erosion of underlying marls with visually distinct gullies.
