• Variable textured subsoil horizons due to prior stream channel deposition.
• High coarse sand and gravel content in top metre of soil profile.

• Plant available water capacity (PAWC) is considered to be relatively low (estimated at approximately 50 mm) for the top metre of the soil profile. This is based on available laboratory data.
• Soluble salt levels are low throughout the profile.
• The high sand and gravel content in the top metre of the soil profile will ensure that infiltration and movement of water will be relatively high.

• The surface soil has a high sand content (77%). Organic matter is important for maintaining aggregation on such soils, as well as for improving soil fertility and water holding capacity.
• The cation exchange capacity of the surface soils is relatively low and nutrients will be more easily leached than in the heavier textured soils.

• The subsoil is weakly structured and has a high quartz gravel content in the upper part. It should be relatively well drained.

• Tractors can become bogged when wet.
