Soil CO2 concentration

Summary

While fluxes of CO2 from the soil to the atmosphere have been studied intensively, relatively little is known about the CO2 concentration in soils. The CO2 concentration in soils is typically much higher than in the atmosphere and it might strongly affect several soil chemical and biological processes. The aim of this project is therefore to better understand how the CO2 concentration in soils changes over time and the biotic and abiotic factors that cause these changes. For this purpose, the CO2 concentration is monitored at high frequency in soils in different ecosystems, located along a climate gradient from North to South Sweden.
