GL84

Location: Digby

Australian Soil Classification: Ferric, Bleached, Grey KUROSOL (confidence level 2)
General Landscape Description: Undulating rises
Site Description: Lower slope, 8% slope.
Land Unit: Digby
Geology: Cretaceous non-marine sandstone

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.
