    Iron is essential for plant growth and is generally considered to be a micronutrient (Thompson and Troeh, 1973). Iron is considered the key metal in energy transformations needed for syntheses and other life processes of the cells. Consequently, plants regulate iron uptake. Ferrous iron is more soluble and bioavailable to plants than ferric iron.

    Iron also can move to the root by diffusion from a region of high concentration to a lower one (at the root surface as Fe is taken up by the plant). Roots also can intercept Fe compounds in the soil as the roots grow and expand into additional soil volume.

  • Iron (Fe) and water Water Treatment and Purification

    Iron usually occurs in soils in tertiary form, but in water saturated soils it is converted to binary iron, thereby enabling plant iron uptake. Plants may take up water insoluble iron compounds by releasing H + ions, causing it to dissolve. Micro organisms release iron siderochrome, which can be directly taken up by plants.
