    Iron is a required plant nutrient for normal plant growth and reproduction. Iron is required in small amounts and is called a micronutrient. Iron is a challenging plant nutrient to work with because of its reactions in the soil and its plant physiology. Iron is typically highly insoluble in the soil used for most plant production systems.Iron is a required plant nutrient for normal plant growth and reproduction. Iron is required in small amounts and is called a micronutrient. Iron is a challenging plant nutrient to work with because of its reactions in the soil and its plant physiology. Iron is typically highly insoluble in the soil used for most plant production systems.Iron Fe is a micronutrient required for plant growth and development however, most Fe forms in soil are not readily available to plants, resulting in low Fe contents in plants and, thereby, causing Fe deficiency in humans. Biofortification through plant-fungal co-cultivation might be a sustainable approach to increase crop Fe contents.areas. Because iron is not translocated in the plant, deficiency symptoms appear on the new growth first. Iron deficiency on individual plants is characterized by yellow leaves with dark green veins interveinal chlorosis. On corn and sorghum, this gives the plants a definite striped appearance. If the condition is severe, the wholeIron is also necessary for physical growth, neurological development, cellular functioning, and synthesis of some hormones 2,3. Dietary iron has two main forms heme and nonheme . Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron .

Further, many metabolic pathways are activated by iron, and it is a prosthetic group constituent of many enzymes. An imbalance between the solubility of iron in soil and the demand for iron by the plant are the primary causes ofFeb 04, 2021 Iron is a constituent of several enzymes and some pigments, and assists in nitrate and sulfate reduction and energy production within the plant. Although iron is not used in the synthesis of chlorophyll the green pigment in leaves, it is essential for its formation. This explains why plants deficient in iron show chlorosis in the new leaves.Jun 23, 2020 In plants, iron is involved in the synthesis of chlorophyll, and it is essential for the maintenance of chloroplast structure and function. Because of its redox properties, its long distance and intracellular trafficking require specialized proteins and low molecular mass chelates because of its insolubility and toxicity in presence of oxygen.
