Acid sulfate soils, sulfidic materials and wetland soils 

Acid sulfate soils are found around the world in both coastal and freshwater environments. These soils are dominated by metal sulfides, which, when exposed to oxygen, oxidise and result in acidification of soil and water. Acidification causes detrimental impacts to agricultural land, natural and managed ecosystems and infrastructure in urban environments. We invite submissions on all aspects of acid sulfate soils, sulfidic materials, and wetland soils in natural, managed and anthropogenic ecosystems.
