No minimum time period is required for reduciton. Any method that shows iron reduction is occurring can be used. C. Redoximorphic Freatures-Introduction 1. Features formed by the reduciton, translocation, and oxidation of Fe and Mn oxides. Both iron and manganese are used because the two are virtually inseparable in soils.
