PhD title: Climate change effect on soil C fluxes – production and transport of CO2 in soils prone to water repellency.
Water repellency (or hydrophobicity) restricts infiltration and affects soil water distribution. In the presence of water repellency large parts of the soil often remain dry even after substantial rainfall. The reduced availability of soil water can directly influence soil C fluxes between soil and the atmosphere. Future climate scenarios with increased temperatures and prolonged dry spells will likely enhance the development and persistence of soil water repellency. The project focuses on investigating CO2 fluxes after the rewetting of hydrophobic soils by combining both, field and laboratory approaches.
