EDDHA Fe 6% Uses

EDDHA Fe 6% is one kind of stable chelated micronutrients which is mainly used in agriculture, horticulture and so on for the supply of flowers, plants and crops. It’s much more effective against iron chlorosis through the roots in calcareous soils. With the help of EDDHA-Fe6, iron can be absorbed by the plant more easily and more iron from the soil becomes soluble, producing the so called “iron shuttle effect”


It is used for:

  1. Treating Iron Chlorosis: Effectively corrects iron deficiencies in plants, a common issue in alkaline and calcareous soils.

  2. Enhancing Plant Health: Promotes healthy growth and vibrant green foliage in plants suffering from iron deficiency.

  3. Agricultural Crops: Widely used in various crops, particularly in fruits, vegetables, and ornamentals, to ensure optimal iron levels.

  4. Soil and Foliar Application: Suitable for both soil drenching and foliar spraying, providing flexibility in application.

  5. Hydroponics: Used in hydroponic systems to supply essential iron in a chelated form for better absorption.

  6. Gardening: Beneficial for garden plants, shrubs, and trees, especially those showing signs of yellowing leaves due to iron deficiency.

  7. Lawns and Turf Management: Helps in maintaining the lush, green appearance of lawns and turf in iron-deficient conditions.

EDTA (Ethylenediaminetetraacetic acid) and EDDHA (Ethylene Diamine Di-2-Hydroxyphenyl Acetate) are both chelating agents used in agriculture to deliver micronutrients to plants, but they have some key differences:

  1. Stability in Soil: EDDHA is more stable than EDTA in alkaline soils with high pH levels. EDDHA-chelated micronutrients remain available to plants in soil pH conditions where EDTA might be less effective.

  2. Micronutrient Affinity: While both can chelate various micronutrients, EDDHA is particularly effective for iron (Fe). EDTA is used more broadly for chelating a range of micronutrients like iron, manganese, copper, and zinc.

  3. Cost and Usage Concentration: EDDHA is generally more expensive than EDTA, but it’s used at lower concentrations due to its higher stability and effectiveness, particularly in alkaline soils.

  4. Application and Effectiveness: EDDHA is often the preferred choice for treating iron chlorosis in plants, especially in calcareous and high pH soils. EDTA is more versatile for providing a range of micronutrients in a wider variety of soil types but is less effective in very alkaline conditions.

  5. Environmental Impact: Both chelates have different environmental impacts. EDDHA is often considered more eco-friendly in terms of biodegradability and soil interaction, especially in sensitive ecosystems.

In summary, the choice between EDTA and EDDHA depends on the specific soil conditions, the micronutrients needed, and cost considerations. EDDHA is typically favored for iron supplementation in alkaline soils, while EDTA is a more general chelating agent for various micronutrients in a broader range of soil types.

EDDHA fertilizer is a specialized type of fertilizer that contains iron chelated with EDDHA (Ethylenediamine-N,N’-bis(2-hydroxyphenylacetic acid)). This formulation is designed to effectively provide iron to plants, particularly in conditions where iron availability in the soil is limited due to high pH levels.

Key aspects of EDDHA fertilizer include:

  1. Iron Availability: EDDHA chelates iron, making it more soluble and available to plants, even in alkaline or calcareous soils where iron typically becomes insoluble.

  2. Preventing Iron Chlorosis: It’s particularly effective in preventing and treating iron chlorosis, a common issue in plants characterized by yellowing leaves due to iron deficiency.

  3. Suitable for Various Crops: Widely used in agriculture, especially for crops sensitive to iron deficiency, such as fruits, vegetables, and ornamentals.

  4. High Efficiency: EDDHA is one of the most effective chelating agents for iron, ensuring that plants can absorb iron efficiently under a wide range of soil conditions.

  5. Application Methods: Can be applied through soil drenching or as a foliar spray, depending on the specific needs of the crop and the severity of the iron deficiency.

EDDHA fertilizer is essential in areas with high soil pH and is valued for its role in maintaining optimal plant health and productivity by ensuring adequate iron nutrition.

Using iron chelate EDDHA effectively involves several steps:

  1. Determine the Need: First, identify if your plants are showing signs of iron deficiency, typically yellowing leaves (chlorosis) while the veins remain green.

  2. Soil pH Check: EDDHA is most effective in alkaline soils with high pH levels. It’s a good idea to test your soil’s pH to ensure EDDHA is the right choice.

  3. Application Rate: Follow the manufacturer’s instructions for the correct dosage. Over-application can be wasteful and potentially harmful.

  4. Mixing: If using a powdered form, dissolve the EDDHA in water as per the recommended rate. For pre-mixed liquid forms, it might be ready to use or require dilution.

  5. Application Method:

    • Soil Drench: Apply the solution directly to the soil at the base of the plant. This method is effective for long-term uptake.
    • Foliar Spray: Spray the solution onto the leaves for quicker absorption. This is beneficial if immediate iron supplementation is needed.
  6. Timing: Apply early in the morning or late in the afternoon to avoid rapid evaporation and to ensure maximum absorption.

  7. Frequency: The frequency of application depends on the severity of the deficiency and the response of the plants. Some plants may require multiple applications.

  8. Safety Measures: Wear protective gloves and follow safety instructions, especially when handling concentrated forms.

  9. Monitor Plants: After application, observe the plants over the following weeks for signs of improvement or any adverse reactions.

  10. Storage: Store any unused product in a cool, dry place, away from direct sunlight and out of reach of children and pets.

Using iron chelate EDDHA correctly can significantly improve the health of plants suffering from iron deficiency, especially in alkaline soil conditions.
