Capturing 3D Water Flow in Rooted Soil by Ultra-fast Neutron Tomography

Abstract Water infiltration in soil is not only affected by the inherent heterogeneities of soil, but even more by the interaction with plant roots and their water uptake. Neutron tomography is a unique non-invasive 3D tool to visualize plant root systems together with the soil water distribution in...
