Linden FairbairnCarbon dioxide (CO2) emissions from soils comprise a major component of the global carbon cycle. The responses of soil CO2 fluxes to changes in environmental conditions remain unclear but are critical for predictive modeling of global carbon fluxes with climate change. Soil moisture and oxygen are two closely related factors that affect rates of aerobic and anaerobic processes in soil. My research aims to improve our process-based understanding of how soil moisture and oxygen affect rates of soil CO2 fluxes. My work involves laboratory soil incubation experiments that inform models for soil CO2 fluxes. In the first phase of my MSc thesis work, I conducted a factorial batch experiment to decouple the effects of soil moisture and oxygen on soil CO2 fluxes and investigated how anaerobic processes contribute to CO2 production in soil. In the second phase, I will further investigate these mechanisms by studying how intrinsic soil properties (e.g., soil texture) affect the relationships between soil moisture, oxygen, and CO2 fluxes. Overall, by developing a better process-based understanding of greenhouse gas-producing processes in soil and their drivers, my research will contribute new insights into models that can accurately represent the complex biogeochemical functioning of soils.
