In soils with fingered flow, surface-applied solutes can reach the groundwater more rapidly than in the case of homogeneous wetting. This study was undertaken to demonstrate the occurrence of finger-like wetting patterns in a silt loam soil and a silty clay loam soil, and to investigate the influence of dry bulk density and water repellency on the observed soil moisture patterns. In both soils, dry bulk density was not a main factor in inducing wet finger-like patterns and high water content variability. Spatial variability of degree and persistence of potential water repellency and, accordingly, of soil water contents were high.
