EDDHA Fe

EDDHA Fe 6% is one of the most potent chelated iron fertilizers used to correct iron deficiency in plants, particularly in high-pH and calcareous soils. It prevents the common problem of chlorosis (leaf yellowing), maintaining a vibrant green color in leaves and promoting healthy growth.

The ortho-ortho (o-o) isomer in EDDHA chelates determines how long the iron remains available to the plant. Different ortho-ortho ratios (1.2–4.8) therefore offer producers both economical and high-performance solutions:

• 1.2 o/o: Short-term effect, cost-effective solution
• 3.0 o/o: Medium-level stability and performance
• 3.6 o/o: High efficacy, a strong solution for challenging soils
• 4.8 o/o: The highest level of stability, with maximum effectiveness in calcareous and high-pH soils

Frequently Asked Questions (FAQ)

• What is EDDHA Fe? EDDHA Fe is a chelated iron fertilizer. It corrects iron deficiency in plants and prevents leaf yellowing (chlorosis).
• Why is the ortho-ortho ratio important? The ortho-ortho isomer determines how long iron remains soluble in the soil. The higher the ortho-ortho ratio, the more long-lasting and effective the product.
• What is the difference between EDDHA Fe 1.2 o-o and 4.8 o-o? The 1.2 o-o form is more economical and has a shorter-term effect, while the 4.8 o-o form provides the strongest and most long-lasting effect.
• Which plants can it be used on? It can be safely used on vegetables, fruit trees, grapevines, field crops, and ornamental plants.
• Can it be sprayed on leaves? No. EDDHA Fe is suitable for soil application only. Foliar spraying is not recommended.
