The effect of tracked vehicles on soil strength and micro-relief of a calcareous earth (Gc1.12) North of Woomera, South Australia.

Abstract

Changes in soil strength and surface micro-relief were measured in a calcareous earth (Gc. 1.12) at a site north of Woomera, before and after the passage of a tracked vehicle. The passage of a tracked vehicle resulted in a reduction of ?oil strength and the formation of ruts. The degree of change depended on the number of vehicle passes and whether the vehicle was travelling in a straight line or turning. Implications for erosion are discussed.
