Soils in the sub-catchment can be divided into four main groups:

• Moderate to deep sandy loam soils on flat and undulating terrain overlying dolomite, limestone and sandstones in the upper reaches of the catchment;

• Moderate to deep clay loam soils over much of the middle portions of the sub-catchment (located away from the river channels), overlying the more porous unconsolidated sedimentary material; and

• Moderately shallow to moderately deep, clayey loam to clay-rich, fine-grained soils over most of the lower reaches of the sub-catchment.  (Ref 2)
