Soil pit GL55 auger

General Land Unit Description:
This land unit has a variety of soil types occurring over a short distance. This soil type, along with Ferrosols and Black Chromosols are found is association with the more dominant Ferric Brown Chromosols. The Brown Chromosols have been used to represent this area as they are deemed to be the major soil type, and due to restrictions of scale the other soil types have not been mapped as individual units. It must be noted however, that the better drained soils (Red Ferrosols / Dermosols) have a higher capability of supporting a range of land uses (e.g. viticulture) due to their favourable physical and chemical properties.
