MM508
| Site: MM508 | Land Unit: Dixie Sedimentary |
| Aust. Soil Class.: Bleached-Mottled, ?, Brown CHROMOSOL (confidence level 3) | |
| General Land Unit Description: The unit consists of gently undulating plains south of Terang. The soils are commonly mottled brown texture contrast soils (Chromosols). The open depressions between the very slight rises consist of acidic grey cracking clays (Grey Vertosols). It is difficult to work these soils for cropping before November, due to waterlogging, but peas have been grown successfully on these soils. |
