MySoil: Pale deep sands (Moora to Kojonup)

Deep white, grey or pale sands. Soil profile at least 80 centimetres (cm) deep before gravels or an increase in texture is encountered.

Broad scale map (1:250 000) of the Moora to Kojonup Agzone showing the distribution of Pale deep sands. The are small scattereed areas of 50–100% naer Cranbook, Cunderdin and Wickepin. There are larger areas of 3–10% near Wikepin, Cunderdin and Moora.
A stylised diagram of the soil profile showing the topsoil and subsoil layers for Pale deep sand (soil group 444).  The soil profile is sand >80cm with grey, white or pale yellow topsoil.
Soil pit showing the profile of Pale deep sand in the Moora to Kojonup region.  The soil profile shows yellow sand, with grey topsoil.

Distinguishing features

Topsoil

  • Pale grey, white or pale yellow in colour.
  • Mainly acid pH.

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 (443).
  • Deep subsoils (>80cm) may contain clay, ferricrete or coffee rock (443, 444).
