Vertosols are clay soils that display shrinking and swelling during wetting and drying cycles. They exhibit strong cracking when dry and at depth have slickensides and/or lenticular peds.
This broad-scale overview map of Vertosols in the North East region has been developed chiefly by Ken Rowe and is based on the Land Systems of Victoria (1:250 000). Other contributors have also assisted in updating the map in areas where they have specialist knowledge. The map shows areas where Vertosols are most likely to occur within the region and should only be used as a general indication of their distribution.
Note that other soil types may also occur within these mapped areas either dominantly or sub-dominantly depending on factors such as climate, landform, geology, vegetation and degree of weathering. This map will continue to be updated as new information becomes available.
Access the Soil and Land Survey Directory from this website to find out about more detailed information from various soil and land surveys that cover parts of this region.
Grey and Black Vertosols have been found in many parts of the North East region, but are not extensive and usually occur in low-lying situations. In many cases their distribution is so isolated that they cannot be shown in the map above. They are most common on the riverine plains in the north west part of the region. Where they are shown to occur on the map, they are mostly only a minor occurrence in association with other soil types.

Previously referred to as:
- Uniform clay soils, cracking clay soils.
Surface (A) horizons
- Mainly on plains in drier north-western parts of the North East region, in lower lying drainage lines within valleys.
light clay texture, clear to abrupt boundary change.
Subsoil (B) horizons
light to medium clay, slickensides present, becoming increasingly alkaline and sodic with depth.
