MM580
| Site: MM580 | Land Unit: Glenthompson Metasediments |
| Aust. Soil Class.: Bleached-Ferric, Natric, Brown KUROSOL (confidence level 2) | |
| General Land Unit Description: This land unit occurs mainly around Glenthompson, although there are scattered occurrences around Balmoral. The landscape is mainly undulating rises with some gentle colluvial slopes. The major soil type on the rises and low hills is a Chromosol, which is commonly sodic at depth (MM583). A dominant soil type on the gentle slopes tends to be a Brown Sodosol (MM578). A co-dominant soil type on the gentle slopes, which is often found in association with the Sodosols, is represented by this site and is a Kurosol, which is often sodic at depth. |
