GL84
| Site: GL84 | Land Unit: Digby |
| Aust. Soil Class.: Ferric, Bleached, Grey KUROSOL (confidence level 2) | |
 | General Land Unit Description: As with the Merino Tablelands land unit, the Digby land unit also occurs on the Cretaceous nonmarine sandstone of the Merino Tablelands. The soils on the Digby land unit differ from the Merino Tablelands land unit as they tend to be slightly more acidic in the top of the subsoil and have more ferruginous nodules (Ferric Brown Chromosols). The division between the two land units is highlighted in recent radiometric imagery. Black Chromosols, Dermosols and Vertosols, similar to the Merino land unit also occur. |
