Factors affecting soil respiration in post mining heaps
 Kopecký, Tomáš ; Frouz, Jan (advisor) ; Kukla, Jaroslav (referee)
The goal of this study is to clarify main sources of CO2 flux from soils of lignite mine heaps near Sokolov (Czech republic) and to quantify the influence of the ecosystem management and spatio-temporal dynamics through the year. In situ experiment took place throughout three years (2018-2021) was used to measure soil respiration. In recultivated areas, respiration was related to temperature, presence of roots and the growing season. In succesion areas, the temperature was found to have main influence on the succesion, whereas the presence of roots and the growing season had none. Sudden isolated occurrences of high values of CO2 flow from the soil were observed in the succession areas, frequent especially outside of the growing season in the colder parts of the year. This led to the assumption that the flow has an abiotic origin. To obtain data on the origin of the soil CO2 flow in the winter, a laboratory experiment was introduced to examine the effect of soil freezing on respiration. It has been shown that even sterile tailings release CO2 and this release is enhanced by freezing, which supports the theory of the abiotic origin of winter episodes with high CO2 production. Finally literary research was written in hope of describing effects influencing soil respiration and respiration involvement in the...
