At typical soil pHs, iron is present in the reduced state as Fe 2+ and in the oxidized state as Fe 3+ (Brady and Weil, 2016). Ferrous iron, Fe 2+, is originally found in primary minerals and is released into the soil solution as a product of mineral weathering, usually mediated by microorganisms (Weber et al., 2006; Colombo et al., 2014). Once ...
