Soil Wettability in Utah Juniper Stands
1971
Scholl, David G.
Wettability varied widely between three ground-cover zones and three soil horizons in a Utah juniper stand [Juniperus osteosperma (Torr.) Little]. Resistance to wetting in the surface soil increased from completely wettable in open areas to highly nonwettable in the litter under the juniper canopy. Resistance to wetting decreased with depth in the soil profile below the litter zone and increased with increasing organic matter. Changes in the soil moisture level also influenced the wettability of the various zones and horizons. Wettability was determined at ⅓ and 15 bars moisture tension and air-dry, with the 15-bar level showing the greatest resistance to wetting.
