Status of soil organic carbon content of selected reclaimed sites in the Podkrušnohorská dump.
KOBESOVÁ, Martina
The main aim of this thesis was to assess the status of soil organic carbon in newly shaped soils called Velká podkrušnohorská dump in the Sokolov district and evaluate the information in relation to the physic-chemical properties of soils. Another objective was to determine the relationship between the stable and labile fractions of soil organic carbon. The amount of soil carbon (stable fraction) was measured in the solid soil samples and there was the analysis of basic physic-chemical parameters of the soil performed. The highest concentration of soil carbon was measured in the stand alders and larch. The amount of soil carbon (labile fraction) was measured in the water extract. The highest values were measured in the stand silver birch and alders. Based on this data the quotient of the labile fraction from the stable fraction was determined and the correlation of the labile and stable fractions was made. It was found out that the higher quality soils are located at the leafy trees, but it leads to leaching of organic carbon. The bulk density and coarse-grained soil fraction was determined from the physical properties and these data were used to calculate the stock of soil organic carbon. The highest value was measured in deciduous forests with small-leaved linden, in coniferous forests with larch. The stocks of soil organic carbon were converted into codes by land cover categories and the thematic map was created. It was found out that the leafy trees are much more appropriate for forest restoration, because they are characterized by the rapid initial growth, easily degradable plant litter and stable form humus. Deciduous forests are also characterized by more developed soil substrate, which is however unstable.
Processes of soil carbon sequestration on reclaimed areas of the Podkrušnohorská dump.
KOBESOVÁ, Martina
The main objective of this thesis was based on samples from the localities to determine the processes of soil carbon sequestration in reclaimed areas of the Velké podkrušnohorské dump and to evaluate the results in relation to physical and chemical properties of soil. The amount of soil carbon was measured from the collected samples and the soil was analyzed of basic physical and chemical soil parameters. The largest concentration of soil carbon was measured in the alder stands.
