Acid sulfate soil assessment and monitoring of the Banrock Station Wetland.

The Banrock Station Wetland Complex is situated in a river red gum floodplain of some 1,375 ha, which includes 1,068 ha of floodplain wetland and 307 ha of an open mallee-box woodland buffer. This investigation encompassed the re-sampling of 29 soil layers, which were collected from six (6) geographically well-distributed and locally representative sites (soil profiles) and analysed using a combination of standard methods: (i) soil morphology, (ii) field pH testing, (iii) peroxide testing, (iv) acid-base accounting (ABA), (v) soil incubation (ageing), and (vi) selected samples for mineralogy. No surface water samples were collected from the floodplain wetlands due to a lack of water at the time of the survey
