SL353/SS555: Iron (Fe) Nutrition of Plants

Uptake of Fe by the plant is an active process, that is, energy is expended by the plant to take in Fe. Iron uptake is dependent on the plant's ability to reduce Fe +++ to Fe ++ and remove it from the complex or chelating compound. Research evidence shows this reduction occurs at the cell surface and that electrons from within the cell are used.
