Description :
The effect of grazing-induced variation in soil surface condition on infiltration and runoff composition was studied at the small patch scale using a rainfall simulator. A range of sites was selected to represent soil surface conditions typical of the more widely distributed rangeland soils in northeastern Queensland. A simple soil surface condition classification scheme relates ground cover and a few easily recognizable surface features to mean infiltration, sediment and nutrient concentration data. Earthworm activity was identified as being a significant factor in recovery of soil hydrological function.
