Experiments on model and real soil blocks designed to assess the feasibility of using magnetic resonance imaging for three‐dimensional mapping of the time‐varying spatial distribution of water in structured soils are reported. The results show that, notwithstanding inherent problems in imaging natural soils with a significant iron content, experimental parameters can be identified which allow satisfactory images to be obtained. Magnetic resonance imaging may therefore provide important information on soil structure and water movement in dual porosity soils, with attendant benefits for the calibration of models of non‐Darcian flow in such soils.
