Contrasting evolution of reactive Fe mineral phases along a paddy soil chronosequence

This dataset includes soil-profile total Fe, ammonium oxalate-extractable Fe, Fe isotope compositions, porewater Fe concentrations and DOC, EXAFS linear combination fitting results, and Mössbauer fitting parameters from a paddy soil chronosequence, supporting analysis of reactive Fe mineral evolution and redox-driven Fe redistribution under long-term rice cultivation.
