When acid sulfate soils dry, oxidation of pyrite can cause acidification and formation of iron (Fe) oxyhydroxy sulfate phases such as jarosite. Remediation via re-establishment of reducing conditions requires submergence and addition of biodegradable

Saturated acid sulfate soils with hypersulfidic material are productive wetland soils, but when they dry, they generate large amounts of sulfuric acid due to oxidation of pyrite to form sulfuric material (pH

Loss of jarosite during remediation of a sandy acid sulfate soil

Autor: Rob Fitzpatrick, Luke M. Mosley, Klaus Kaiser, Angelika Koelbl, Robert Mikutta, Petra Marschner

When acid sulfate soils dry, they generate large amounts of sulfuric acid due to oxidation of iron (Fe) sulfides (e.g., pyrite), causing formation of Fe sulfates such as jarosite and strong acidification (pH We investigated the remediation of a sandy
