North West Victoria: Mallee

Calcarosols

Gc

60%
Sand to clay loam surface soils grading to a sandy loam to clay subsoil, calcareous throughout, often with soft or hard calcareous nodules. Found on dunefields and plainsSurface: water repellence.
Subsoil: high clay content.

North West Victoria: Mallee

Rudosols and Tenosols

Uc

35%
Sandy soils that may have a restrictive horizon (iron/organic pan) at depth below a bleached horizon. Found on dunefields and sandplains.Surface: water repellence, nutrient retention.
Subsoil: nutrient retention.

North West Victoria: Mallee

Vertosols

Ug

5%
Grey cracking clay soil with self-mulching to coarse structured surfaces. High shrink-swell soils causing local irregular ground surface (melonhole/gilgai). Found in swales and depressions in dunefields and plains.Surface: compaction, high clay content and shrink-swell properties.
Subsoil: compaction, coarse structure, high clay content and shrink-swell properties.

North West Victoria: Southern Mallee / Northern Wimmera

Vertosols

Ug

45%
Grey cracking clay soil with self-mulching to coarse structured surfaces. High shrink-swell soils causing local irregular ground surface (melonhole/gilgai). Found in swales and depressions.Surface: compaction, high clay content and shrink-swell properties.
Subsoil: compaction, coarse structure, high clay content and shrink-swell properties

North West Victoria: Southern Mallee / Northern Wimmera

Calcarosols

Gc, Uf

15%
Loam to light clay surface soils grading to a clay loam to medium clay subsoil, calcareous throughout (often with hard calcareous nodules). Found on dunefields and associated plains. Surface: water repellence
Subsoil: high clay content.

North West Victoria: Southern Mallee / Northern Wimmera

Tenosols, Rudosols

Uc

15%
Sandy soils that may have a restrictive horizon (iron/organic pan) at depth below a bleached horizon. Found on dunefields and sandplains.Surface: water repellence, nutrient retention.
Subsoil: nutrient retention, deep drainage.

North West Victoria: Southern Mallee / Northern Wimmera

Sodosols (yellow/brown)

Dy

15%
Loam (fine sandy) surface and loamy bleached subsurface visibly over a mottled brown, yellow and grey clayey subsoil. Occasionally calcareous at depth. Found on sandplains and depressions.Surface: water repellence, nutrient retention, potential surface sealing.
Subsoil: compaction, dense and coarse structure, shrink-swell properties.
