Kvalifikace primární půdní organické hmoty podle rychlostní konstanty oxidace v půdách porostů energetických rostlin

This Bachelor thesis is focused on monitoring the yield parameters of selected energy plants (Elymus elonganus, Phalaris arundinacea L., Miscanthus × giganteus). First part of the work was performed at the experimental site of the Faculty of Agriculture of the University of South Bohemia in České Budějovice, where long-term experiments were carried out to look at the yields of these plants. I was observing the yield of crops grown for the purpose of incineration, which are harvested once a year before the beginning of the growing season. Research has shown that on a 4-year average the most profitable species is Miscanthus × giganteus. The second practical part of my work was the sampling and analysis of soil samples from these stands and, for comparison, the sampling of soil under permanent grassland. In the laboratory at the Department of Agroecosystems the samples were modified and examined in terms of the quantity and quality of soil organic matter. The analysis shows that the content of humus in soils with energy plants is lower in comparison to the content of these substances in soil under permanent grassland. There were no significant differences in the observed values of the velocity constants of the oxidation of the primary soil organic matter
