title: STRAFI-NMR studies of water transport in soil.
abstract: 1-D STRAFI (STRAy FIeld) imaging is used to study water distribution in a sandy loam. The matric potential of the soil can be varied during acquisition of 1-D profiles. Results at a range of potentials are presented showing both the equilibrium distribution and the evolution of the profile following an abrupt change in matric potential. The air breakthrough point and variations in draining behaviour due to differences in soil compaction are identified.
