Tenosol AU

A representative soil profile in a map unit of brown, yellow and red sands >80 centimeters (cm) deep. These are deep loose sandy, moderately acid soils. Sands have medium to coarse textures. These soils are from the colored deep sands of the West Midlands of Australia.

Topsoil

Brown, red or yellow medium to coarse textured sands.

Loose sands with acidic pH trend.

Subsoil

Ironstone gravel may be present

Subsoils sands often acid to neutral pH

Limestone or ferricrete may be present >80cm

In the Australian soil classification system, the soils in this unit are dominantly Orthic Tenosols, including: Aeric Podosols, Red-Orthic Tenosols, or Yellow-Orthic Tenosols.

 

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:
