Correction of iron deficiency where added to different irrigation systems because the claw segment is stable and dissolved over a wide range of pH (3 - 12), which makes it absorbed by the plant does not prove in the soil is considered iron from the materials consumed by the plant as a result of iron ability to enter in Oxidation and reduction reactions within the plant, iron is considered to have significant physiological effects. Iron plays an essential and necessary role in the system of many enzymes, especially the enzymes involved in the formation of many vital processes such as breathing, including Catalase, Peroxidase and Cytochrome oxidase. The involvement of iron in the composition of these compounds is particularly important in oxidation processes and is one of the important roles in the processes of methabolism in the cell.
