MM726
| Site: MM726 | Land Unit: Buckley Swamp Peats |
| Aust. Soil Class.: Terric, Acidic, Sapric ORGANOSOL (confidence level 4) | |
| General Land Unit Description: Buckley Swamp consists of a valley infilled by an earlier lava flow, with the subsequent blockage of the drainage line resulting in peat accumulation. The area has been drained and burnt at various times in the past, resulting in some decomposition and loss of peat. The dominant soils of the plain are Organosols with massive or well-structured surfaces. The soils of the backplain are commonly Hydrosols with well structured surfaces and peaty horizons. There are also minor occurrences of Vertosols. |
