Iron transformations impact the physical and chemical properties of forested wetland soils and influence the development and stabilization of soil structure. Although it is well known that paddy soils are subject to a succession of iron transformations from ferric to ferrous states under reducing conditions, the dynamics of iron in submerged forest soils have been less studied in China. Transformations of iron, changes in soil redox potential (Eh), and soil pH variations associated with submergence are inte...
