Infiltration and Soil Stability of a Summer Range

Abstract

Infiltration and sediment production rates, under simulated rainfall, were determined for plots covered with mule-ear wyethia and on plots from which wyethia had been replaced by grasses as a result of spraying. The sediment produced during the 50-minute period averaged 0.447 ton/acre. As the infiltration rates for the wyethia and grass plots (2.74 and 2.38 inches/hour, respectively) were not significantly different, single equations expressing average infiltration rates and mass infiltration were derived for extrapolating experimental results to other areas with similar vegetation.
