It is one of the most deficient elements in our country's soil. However, its deficiency is not due to its scarcity in the soil, but due to its high pH and high lime content. At high pH and high lime rates, iron forms insoluble compounds.

Iron deficiency first manifests itself in young leaves and especially newly formed ones. In advanced cases of iron deficiency, the leaves may turn white because no chlorophyll can be synthesized. The characteristic symptoms of iron deficiency are growth arrest caused by cessation of chlorophyll synthesis.

Iron is the essential nutrient in the formation of chlorophyll.

• It is absolutely necessary for the transformation of chlorophyll.
• It is effective in the formation of chloroplastic protein.
• It acts as an enzyme and co-enzyme.
• It is necessary for the electron transfer of enzymes.

• The deficiency is first seen in young leaves.
• Deficiencies can be expected in areas with high lime content, high pH or excessive phosphorus fertilization.
• Typically, chlorosis (yellowing) occurs between the veins in young leaves, while the veins remain green. When severe, the veins may also turn yellow and the leaf may turn completely white.

• Soils with high pH, high lime content and high EC.
• Soils containing high levels of heavy metals.
• Low potassium level. Low zinc and high manganese content in the plant.
• Soils with poor drainage and aeration.
• Plants planted in the past consumed iron.
