Appendix 5
Approximate correlations between the Australian and other soil classifications
| Order | Great Soil Group | Factual Key | Soil Taxonomy Order |
|---|---|---|---|
| CALCAROSOLS | Solonised brown soils, grey-brown and red calcareous soils. | Gc1, Gc2, Um1, Um5 soils | Aridisols, Alfisols |
| CHROMOSOLS | Non-calcic brown soils, some red-brown earths and a range of podzolic soils | Many forms of duplex (D) soils | Alfisols, some Aridisols |
| DERMOSOLS | Prairie soils, chocolate soils, some red and yellow podzolic soils | Wide range of Gn3 soils, some Um4 | Mollisols, Alfisols, Ultisols |
| FERROSOLS | Krasnozems, euchrozems, chocolate soils | Gn3, Gn4, Uf5, Uf6 soils | Oxisols, Alfisols |
| HYDROSOLS | Humic gleys, gleyed podzolic soils, solonchaks and some alluvial soils | Wide range of classes, Dg and some Uf6 soils probably most common | Alfisols, Ultisols, Inceptisols, salic Aridisols, Histosols |
| KANDOSOLS | Red, yellow and grey earths, calcareous red earths | Gn2, Um5 soils | Alfisols, Ultisols, Aridisols |
| KUROSOLS | Many podzolic soils and soloths | Many strongly acid duplex soils | Ultisols, Alfisols |
| ORGANOSOLS | Neutral to alkaline, and acid peats | Organic (O) soils | Histosols |
| PODOSOLS | Podzols, humus podzols, peaty podsols | Many Uc2, some Uc3, Uc4 soils | Spodosols, some Entisols |
| RUDOSOLS | Lithosols, alluvial soils, calcareous and siliceous sands, some solonchaks | Uc1, Um1, Uf1, soils | Entisols, salic Aridisols |
| SODOSOLS | Solodized solonetz and solodic soils, some soloths and red-brown earths, desert loams | Many duplex (D) soils | Alfisols, Aridisols |
| TENOSOLS | Lithosols, siliceous and earthly sands, alpine humus soils and some alluvial soils | Many Uc and Um classes | Inceptisols, Aridisols, Entisols |
| VERTOSOLS | Black earths, grey, brown and red clays | Ug5 soils | Vertisols |
This table is intended only to give an idea of soils which approximately correspond to the orders of the new scheme. It is not meant to be used as an accurate translation between the various classification schemes. In many cases only major nearest equivalents can be given as differentiating criteria often differ between the four systems. No equivalent classes are available for Anthroposols, although some would fit into Entisols.
