Soil-, root systems and rhizosphere processes
The aim of the research unit "Soil- root systems and rhizosphere processes" is to contribute to the improvement of our understanding of soil-root interactions through combined use of mathematical modelling and non-invasive methods of soil-root systems analysis. This improved understanding will allow to define recommendations for sustainable agricultural productions and breeding.
Model development focuses on models of root system growth that are responsive to the soil environment. Examples include root system P uptake from low-P soils including plant adaptations such as root architecture plasticity, root hair development, root exudation and the symbiosis with arbuscular mycorrhizal fungi. Multiscale modelling is used to reflect the fact that various scales are involved in those interactions.
Three-dimensional images from non-invasive imaging techniques are used to extract root system parameters as well as for model calibration and validation.
