Here we tested plants’ ability to use iron (Fe) from the water-soluble commercial product Humiron (a complex of Fe with highly purified and solubilized humic acids extracted from leonardite) as a source of chelated Fe for both strategy 1 (e.g. cucumber) and strategy 2 (e.g. barley) plant species grown under low Fe conditions. Iron from radioactive 59Fe-labelled Humiron can easily be acquired by strategy 1 plant species via reduction of FeIII by the inducible plasma membrane-bound reductase, similarly to the reduction of synthetic FeIII-chelates. Strategy 2 plant species can also efficiently utilize Fe from Humiron via ligand exchange between humates and phytosiderophores (PS). Moreover, the efficacy of Humiron is comparable to Fe complexed with water- extractable humic substances obtained form peat. Being easily biodegradable this product can be used as an effective Fe source for organic crop production.
