Tenosol AU

A representative soil profile in a map unit of white, grey or pale sands overlying gravels to depths of at least 80 centimeters (cm). These soils are pale deep sands of the West Midlands of Australia. (Base photo provided by Department of Primary Industries and Regional Development, Agriculture and Food, Government of Western Australia.)

 

Topsoil

Pale grey, white or pale yellow in color.

Mainly acidic pH trend though to alkaline throughout.

Subsoil

Subsoil dominated by sand to depths of at least 80cm.

Subsoils often highly leached, poor nutrient status and retention.

Less than 20% Ironstone gravel maybe present below 15cm depth in a band at least 20cm thick

Deep subsoils (> 80cm) may contain clay, ferricrete or coffee rock

In the Australian soil classification system, the soils in this unit include: Shelly Rudosols, Shelly Calcarosols, Sesqio-Nodular Tenosols, Ferric Bleached-Orthic Tenosols. Bleached –Orthic Tenosols, Aeric Podosol. Ferric-Petroferric Bleached-Orthic Tenosols, Arenic Bleached-Orthic Tenosols, or Basic Arenic Rudosols.

 

Tenosols have only weak soil profile development and are often shallow. In the Australian Soil Classification they are defined as having limited subsoil (B horizon) development (less than 15% clay content). However, Tenosols have more development than the most rudimentary soils i.e. Rudosols as they include bleached layers and colour changes

 

Orthic Tenosols occur on the younger parts of the landscape in lower rainfall areas. They are formed on the steep hills in the north and in the rain shadow area around Omeo. They are more prevalent on the drier north and northwest aspects. These soils often merge with Kandosols as the clay content can be slightly higher than specified as the upper limit for Tenosols (i.e. 15%).

In Soil Taxonomy, these soils are primarily Inceptisols or Entisols. For more information about Soil Taxonomy, visit:
