Iron Role in plants.

Iron is an essential micronutrient required for plant growth and development. It is a component of many enzymes involved in important metabolic processes, such as photosynthesis and respiration. Iron is also required for the synthesis of chlorophyll, the green pigment that is essential for photosynthesis.


Iron is primarily absorbed by plants in its ferrous (Fe2+) form. In most soils, iron is present in its ferric (Fe3+) form, which is insoluble and unavailable for plant uptake. However, some plants have developed mechanisms to acidify the soil around their roots, which converts the ferric form of iron to the ferrous form and makes it available for plant uptake.

Iron deficiency in plants can lead to chlorosis (yellowing) of leaves, stunted growth, and reduced yields. The symptoms of iron deficiency are most apparent in the youngest leaves, which will turn yellow while the veins remain green.

Iron toxicity can also occur in plants when they are exposed to high levels of iron in the soil. This can lead to leaf bronzing, stunted growth, and reduced yields. Iron toxicity is more likely to occur in acidic soils, where iron is more soluble and available for plant uptake.

To address iron deficiency in plants, iron can be added to the soil in the form of iron chelates or ferrous sulfate. Iron can also be applied as a foliar spray. To address iron toxicity, it is important to reduce the amount of iron in the soil or adjust the soil pH to a more neutral range. In some cases, it may be necessary to leach the soil with water to remove excess iron.
