MUCILAGE: The hydraulic bridge between soil and plants


From 01/2013 to 12/2017

Principal Investigator: Andrea Carminati
Staff: Mutez Ali Ahmed, Andrea Carminati
Grant: DFG CA921/2-1 MUCILAGE: The hydraulic bridge between soil and plants

The aim of the project is to characterize the physical and chemical properties of root exuded mucilage and its effects on water flow in soils and root water uptake. This project is a collaboration with the University of Landau (Prof. Gabriele Schaumann) and UFZ-Halle (Prof. Doris Vetterlein).
