How EDDHA Fe 6% Improves Iron Availability and Enhances Plant Growth

EDDHA Fe 6% is a highly effective chelated iron fertilizer designed to correct iron deficiencies in plants. It is widely used in agriculture and horticulture to prevent and treat chlorosis, a condition caused by insufficient iron uptake. With its superior solubility and stability, EDDHA Fe 6% ensures optimal iron absorption even in alkaline and calcareous soils, promoting healthy plant growth and high crop yields.

What Is EDDHA Fe 6%?

EDDHA Fe 6% is an iron chelate in which iron (Fe) is bound to ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (EDDHA). This stable chelation prevents iron precipitation in high pH soils, ensuring plants receive the necessary iron for essential metabolic functions, including chlorophyll production, enzyme activation, and energy transfer.

Key Features of EDDHA Fe 6%

• Highly Stable Chelate – Remains effective even in alkaline soils with pH up to 11.

• Rapid Iron Absorption – Ensures quick uptake, preventing and treating iron deficiency.

• Prevents Chlorosis – Promotes chlorophyll synthesis, maintaining vibrant green foliage.

• Enhanced Solubility – Easily dissolves in water for efficient foliar and soil application.

• Boosts Plant Growth – Supports enzyme activation, energy production, and overall plant metabolism.

• Long-Lasting Effect – Provides a sustained iron supply, reducing the need for frequent applications.

• Suitable for All Crops – Ideal for fruits, vegetables, cereals, and ornamental plants.

Applications of EDDHA Fe 6%

1. Soil Application – Corrects iron deficiency in high pH soils where iron is typically unavailable.

2. Foliar Spray – Provides immediate correction of iron deficiency for faster results.

3. Fertilizer Additive – Enhances the efficiency of compound fertilizers and nutrient solutions.

4. Hydroponics & Drip Irrigation – Delivers a precise iron supply for soilless growing systems.

5. Tree Injections – Used in orchards to prevent iron deficiency in fruit-bearing trees.

• Slow Visual Response in Some Crops – Although effective, visible improvements may take a few days depending on the plant species and deficiency level.

FAQ

Q1: Why is EDDHA Fe 6% better than other iron chelates?
A1: Unlike EDTA and DTPA, EDDHA Fe 6% remains stable and effective in alkaline soils (pH 7–11), ensuring continuous iron availability to plants.

Q2: How is EDDHA Fe 6% applied?
A2: It can be applied through soil drenching, foliar spraying, hydroponics, or drip irrigation, depending on crop type and deficiency severity.

Q3: Can EDDHA Fe 6% be used in organic farming?
A3: While EDDHA is synthetic, it is widely accepted in integrated and sustainable farming practices due to its high efficiency and eco-friendly properties.

Q4: How often should EDDHA Fe 6% be applied?
A4: Application frequency depends on soil conditions and crop needs. Typically, one application per growing season is sufficient, but severe deficiencies may require additional treatments.

Q5: Can EDDHA Fe 6% be mixed with other fertilizers?
A5: Yes, it is compatible with most fertilizers and nutrient solutions. However, avoid mixing with highly acidic or phosphate-rich solutions to prevent precipitation.

EDDHA Fe 6% is a premium iron chelate that ensures optimal iron availability in alkaline soils, preventing chlorosis and promoting healthy plant growth. Its superior stability, fast absorption, and long-lasting effect make it an essential solution for high-yield agriculture and horticulture.
