Data for: Rhizosphere effect and its associated soil-microbe interactions drive iron fraction dynamics in tidal wetland soils

root trait (root biomass, root length and root porosity)
Fe fractions (non-sulfidic Fe(II), amorphous Fe(III), crystalline Fe(III), FeS and FeS2)
Soil and porewater (pH, Fe2+, dissolved organic carbon, bicarbonate, sulfate and changes in sulfate)
microbial abundances (Geobacter, Gallionella and Total bacteria)
