Studies performed in a field indicate that podzolic soil combined with sewage sludge under Salix viminalis L. cultivation exhibited an increase in lipolytic bacteria and fungi numbers as well as a clear stimulation of lipase activity at level A. These changes increased in accordance with the increase of sludge concentration in the soil, and remained in the second and the third year of the experiment...
In pot experiments conducted in the plant house, an investigation was carried out upon the influence of soil moisture on the uptake of metals by plants, as well as the contents in soil in their soluble forms. In the experiments, plant species with various abilities for element accumulation were cultivated, and soils with lowered or elevated Cd contents were used. An assessment was carried out in the...
Manganese contents in various extracts (2 M HN03, 0.05 M EDTA and 0.01 M CaCl2) and total Mn content in soil samples of various soil types from 6 regions of Slovakia were determined. After simulated loading the Mn extraction in 2 M HN03 decreased in order Lgp > Hcf > Jc Chc > Lga > Rc. The same order was also in 0.05 M EDTA and 0.01 M CaCl2. The results showed that Mn extractability is...
The majority of podzolic soils among the soils of forest-ecosystems is characteristic of the immediate surroundings of the city of Zielona Góra. In the smaller areas, rust and brown soils are evident, and in the low-lying enclaves also mursh and black earth. Changes in use (the area is more heavily used than before) and in the tree stand (the mechanical works and the litter character changes) as well...
Soil is a major reservoir for contaminants as it posseses an ability to bind various chemicals. These chemicals can exist in various forms in soil and different forces keep them bound to soil particles. It is essential to study these interactions because the toxicity of chemicals may strongly depend on the form in which they exist in the environment. Another thing is that soil variability and some...
