Resumen:
This document is applicable to determine the content of "reactive" iron in the form of crystralline iron oxides and hydroxides in soil and materials by extraction with dithionite. This content of "reactive" iron can be used as input in geochemical models to represent the content of crystalline iron (hydr)oxides.
