Description	Plant cover and surface crusts can influence soil hydrology considerably after long periods of hot weather and drought when water repellency (WR) is greatest. This was studied on an aeolian sandy soil that frequently experiences long dry and hot weather, followed by intense precipitation. The different vegetation covers examined were (1) predominantly grass species (grassland soil); (2) a 30-year-old Scots pine forest (forest soil); (3) mainly moss species (glade soil) and (4) subsoil at 50-cm depth of treatment (5) to remove the influence of vegetation or soil crusts (pure sand). Vegetation cover influenced hydrological and pedological properties of the sandy soil. Both the water drop penetration time (WDPT) and WR index R decreased in the order: forest soil - glade soil = grassland soil - pure sand. WDPT and R were up to 3 orders of magnitude greater, whereas sorptivity and hydraulic conductivity were up to 3 orders of magnitude less, in some vegetated soils compared to pure sand.
