Kvalita nezhumifikované půdní organické hmoty v půdách porostu rostliny Miscanthus × giganteus
 SKOBA, David
The diploma thesis is focused on observing the yield parameters of the plant Miscanthus × giganteus and on monitoring and comparing the content of soil organic matter under this stand in two variants (Cut, Uncut) and the adjacent fallow (control variant - Fallow variant). The experiments took place at the experimental site of the Faculty of Agriculture of the University of South Bohemia in České Budějovice, where the growth of this plant was established several years ago and experiments are carried out every year aimed at observing the yield of this plant. Field work consisted of taking phytomass and monitoring the yields of the monitored plant. Furthermore, soil samples were taken from individual management variants for subsequent analysis. The quantity and quality of soil organic matter was monitored in the laboratory. The yield of dry matter in the Uncut variant exceeded 20 t ? ha-1. Furthermore, it was found that the date of soil sampling had an effect on the amount of organic matter in the soil. In the summer months (July and August 2019) a higher content of carbon of primary soil organic matter, carbon of stable fractions of soil organic matter and total organic carbon was recorded. The carbon content of stable organic fractions is influenced by different management. While the highest was in the Fallow variant, the lowest content was in the Cut variant, the difference between the two variants was statistically significant. The content of total organic carbon was the highest in August 2019, when it reached 3.1%.
