EDTA-Fe is a chelated form of iron fertilizer, where iron is bonded with EDTA (Ethylenediaminetetraacetic acid) to enhance its absorption and effectiveness in plants. This formulation is particularly useful in preventing and treating iron chlorosis, a condition marked by yellowing leaves due to iron deficiency. EDTA-Fe is highly effective in various soil types, especially in alkaline conditions where iron is less available to plants. It’s widely used in agriculture and horticulture to ensure optimal iron levels, crucial for plant growth and chlorophyll production.

EDTA-FE Manufacturing Process

The manufacturing process of EDTA-Fe involves:

Synthesizing EDTA: Creating EDTA (Ethylenediaminetetraacetic acid) through a chemical reaction involving ethylenediamine and other compounds.
Iron Chelation: Reacting the synthesized EDTA with an iron salt (like iron sulfate) to form the iron-EDTA chelate.
Purification: Purifying the chelated compound to remove impurities and ensure product quality.
Concentration Adjustment: Adjusting the concentration to achieve the desired ratio of iron in the final product.
Quality Testing: Conducting tests to ensure the product meets agricultural standards for purity and efficacy.
Packaging: Packaging the final EDTA-Fe product for distribution, typically in powder form.

This process results in a stable, bioavailable form of iron, suitable for addressing iron deficiencies in plants.



EDTA-FE Solubility

HUMICO EDTA-Fe is highly water-soluble, ensuring that the iron it contains is readily available for plant uptake. This solubility is crucial for its effectiveness in agriculture, allowing for easy application through soil drenching or foliar spraying and ensuring efficient absorption by plants.

EDTA-FE Function & Application

EDTA-Fe is mainly used as spraying fertilizer, water flush fertilizer, drip irrigation fertilizer, water-soluble fertilizer, organic fertilizer, raw materials of Compound fertilizer, also used as soilless cultivation.


Function of EDTA-Fe:

  1. Iron Supplementation: Provides a stable and bioavailable source of iron, essential for chlorophyll synthesis and photosynthesis in plants.

  2. Prevents Iron Chlorosis: Effectively treats and prevents iron chlorosis, characterized by yellowing leaves while veins remain green.

  3. Enhances Plant Health: Improves overall plant health, vigor, and productivity, particularly in iron-deficient soils.

Application of EDTA-Fe:

  1. Foliar Spray: Applied directly to plant leaves for quick absorption and immediate correction of iron deficiency.

  2. Soil Drench: Used as a soil amendment to increase iron levels in the soil, ensuring long-term availability to plants.

  3. Hydroponics: Incorporated into nutrient solutions in hydroponic systems to provide essential iron.

  4. Gardening and Agriculture: Suitable for a wide range of plants, including crops, ornamentals, and lawns, especially in alkaline and calcareous soils.

  5. Preventive Treatment: Applied as a preventive measure in areas known for iron-deficient soils.

EDTA-Fe is a versatile tool in plant nutrition, effectively addressing iron deficiencies and enhancing plant growth and development.


Benefits of EDTA-FE

HUMICO EDTA-Fe offers several benefits:


  1. Effective Iron Delivery: Ensures efficient delivery of iron to plants, crucial for photosynthesis and overall health.

  2. Prevents Iron Chlorosis: Effectively treats and prevents iron chlorosis, characterized by yellowing leaves due to iron deficiency.

  3. High Bioavailability: The chelation with EDTA makes iron more bioavailable to plants, especially in alkaline soils where iron availability is limited.

  4. Rapid Absorption: Suitable for foliar application, allowing plants to quickly absorb iron directly through their leaves.

  5. Versatile Use: Can be used in various agricultural settings, including fields, hydroponics, and gardens.

  6. Improves Plant Health: Promotes healthier plant growth, enhances chlorophyll production, and improves overall crop quality.

  7. Eco-Friendly: As a chelated form of micronutrient, it minimizes the risk of soil contamination compared to non-chelated forms.

  8. Enhances Disease Resistance: Adequate iron nutrition can enhance a plant’s resistance to certain fungal and bacterial diseases.

  9. Suitable for a Range of Crops: Effective for a wide variety of crops that require iron for optimal growth.

  10. Stable in Various Soil Types: Remains effective across a range of soil pH levels, ensuring consistent performance.

EDTA-Fe is particularly useful in enhancing crop yield and quality by ensuring adequate iron nutrition.


Ultimate FAQ to EDTA-FE

EDTA (Ethylenediaminetetraacetic acid) reacts with iron to form a chelated complex, specifically with iron ions (Fe2+ or Fe3+). This reaction is a process of chelation, where EDTA, a chelating agent, binds to the iron ion. Here’s a simplified overview of the reaction:

  1. Formation of the Chelate: EDTA has multiple amino and carboxyl groups that act as electron donors. When EDTA is introduced to a solution containing iron ions, these groups coordinate with the iron ion, forming a stable ring-like structure. This structure effectively “encases” the iron ion.

  2. Stabilization of Iron: The chelation process stabilizes the iron ion, preventing it from forming insoluble and unavailable compounds in the soil, especially in alkaline conditions.

  3. Resulting Complex: The resulting EDTA-iron complex is a stable, water-soluble form of iron. This solubility is crucial because it keeps the iron in a form that plants can easily absorb, either through their roots or leaves.

  4. Prevention of Precipitation: In soils, especially those with high pH, iron tends to form insoluble compounds that plants cannot uptake. The EDTA-iron chelate prevents this precipitation, ensuring that iron remains available to plants.

The reaction between EDTA and iron is a key process in creating an effective form of iron supplementation for plants, particularly in environments where iron availability is a challenge.
