Non-invasive or minimal invasive methods to measure and monitor soil state variables, fluxes and structural properties are becoming increasingly important in soil physics. These methods include Magnetic Resonance Imaging (MRI), Neutron scattering techniques, X-ray tomography, spectroscopic methods, and geophysical methods such as ERT, SIP, EMI and GPR. These methods have been applied to determine the spatial and temporal distribution of soil water content, characterize root water uptake processes in undisturbed soil monoliths or to derive soil hydraulic parameters at scales ranging from the pore to the field scale. In this session, we welcome contributions that focus on the applications of non-invasive methods to improve our understanding of soil physical processes and contribute to improved characterization of soil physical parameters. We particularly solicit papers that present new results in the development of non-invasive methods and advanced processing algorithms that improve our capability of interpreting and transforming measured information.
