| Vertosols, or cracking clay soils, occur in four situations - on floodplains, ridged plains, volcanic plains and palaeolacustrine plains. Large floodplains on which grey Vertosols predominate occur beside the Murray, Loddon and Wimmera Rivers, whilst other streams have smaller occurrences. Salinity status is generally low. However, poor surface structure usually limits agricultural use to grazing. The ridged plain of the Wimmera is dominated by Grey Vertosols with self-mulching surfaces and alkaline sodic subsoils. The land is heavily cropped. Other soils include red, brown and grey Sodosols. |
This map of Vertosols in the North Central region has been developed by Jim Rowan and is based mainly on the Land Systems of Victoria (1:250 000) with some use of the Atlas of Australian Soils (Northcote 1962). It shows areas where Vertosols are most likely to occur within the region. Note that other soil types may also occur within these mapped areas (although they are likely to be a more minor component). | Vertosols North Central Region |
