When acid sulfate soils with hypersulfidic material dry, oxidation of pyrite can cause strong acidification due to formation of sulfuric (pH < 4) material. Re-saturation of acid sulfate soils containing sulfuric material can lead to re-formation of pyrite and pH increase through activity of sulfate reducing bacteria, which require available organic carbon (OC). In the Lower River Murray region in Australia, a clayey acid sulfate soil had acidified during the severe “Millennium” drought between 2007 and early 2010. We investigated why it has not recovered for over a decade after being reflooded. We hypothesized that the low quality and availability of OC limits the activity of sulfate reducing bacteria. A long-term anoxic incubation experime...
