This map unit is confined to the valleys of Mitchell River near Bairnsdale and the Tambo River south of Bruthen.


Mitchell River flats looking south towards Lindenow

Original vegetation
Dry valley forest, minor areas of floodplain reed-bed.

Soils
Component 1: Soils on flood plains
Most of the soils of this map unit occur on the flood plains. Generally they are moderately to slightly acidic dark greyish brown deep fine sandy to silty loams and silty clay loams, but layers of coarser material such and stones and gravel may occur deeper in the subsoil. Three soil profiles are described: Mitchell River flats, Tambo River flats south of Bruthen and near the Tambo River mouth.

Component 2: The stream channel
This is a very minor component of the map unit. Bed and bank erosion is common along the stream channels.

Land use
Mitchell River flats are used extensively for vegetable production with some grazing and the Tambo River flats for grazing.

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.
