Management Considerations

Whole profile

The brown colours throughout and lack of texture contrast indicate the profile is well drained internally.
Plant available water content capacity is considered to be low to moderate, (estimated at 62 mm) based on the laboratory data and an effective rooting depth of 70 cm.

Surface (A11) horizon

The soil has a normal organic matter content conferring average structural stability,
The nutrient holding capacity of the soil is moderate (based on the sum of exchangeable cations),
The potassium levels are low and the soil is expected to show a strong response to potassium fertilisers.

Subsurface soils

The soil has no impeding layers to restrict root development.
