Living matter in soil can have potentially massive implications to hydrological and chemical processes. Over the past few years there have been major advances in understanding the link between biological, hydrological and chemical processes in soil, driven by the need to mitigate deleterious land management practices. In addition to more apparent processes such as water and solute uptake by roots, transpiration, as well as water and solute transport via biopores (macropores formed by plant roots and burrowing soil animals), new research has shown that soil hydrological and chemical processes can be affected by the chemicals released from decaying leaves and roots, soil animal (earthworms, ants, etc.) exudates, as well as root and microbial mucilages that change pore characteristics by aggregating soil particles and influencing the soil-water contact angle. Recent research also addresses influences of biological processes in the rhizosphere on leaching of chemicals, e.g. in the field of phytoremediation. In this session we aim to present fundamental research on biology-hydrology-geochemistry interactions, and new measurement and modelling techniques that are helping us unravel this complex problem. Contributions can vary from microscale hydrological processes caused by a specific microbe, through plot-scale studies dealing with the impact of soil water repellency and preferential flow, up to the impact of large-scale shifts in soil biological processes caused by land management.
