Abstract:

Both abiotic and biotic factors such as heterotrophic soil breathing, groundwater level, local climate conditions, plant physiological parameters and species composition significantly impact Greenhouse Gases (GHGs) emissions. An interdisciplinary research approach helps to assess GHGs emissions measurements and also to gain an understanding of the plant related physiological processes and carbon storage in the ecosystem, so that more efficient management solutions can be developed that contribute to climate neutrality goals. This study aimed to develop a model system under semi-controlled conditions to assess the impact on the GHGs emission at the different ground water level (+1, -5, -15, -25, -35 cm) and accumulated biomass using the mid-infrared light spectrometer. The total CO2 emission was higher in the plots with vegetation and the difference between bare soil increases with decreasing groundwater level. CH4 emissions were low in the first two groups with lower water levels (-35cm and -25cm) but increased rapidly in groups with higher water levels. Reduced CO2 emissions were observed as the water level rises, and these changes were more rapid in the groups with vegetation.
