EDDHA Fe 6 %

General Properties and Industrial Significance:

EDDHA Fe 6% refers to a chelated iron product where iron (Fe²⁺ or Fe³⁺) is bound to EDDHA (ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid)), a highly effective chelating agent. The product contains 6% iron by weight, meaning that in 100 grams of the product, 6 grams are iron, and the remaining portion consists of the EDDHA chelating agent and stabilizers.

EDDHA Fe 6% is a water-soluble chelated iron fertilizer used to correctiron deficiencies in plants.

EDDHA (Ethylene diamine-N,N'-bis(2-hydroxyphenylacetic acid)) is an advanced chelating agent known for its ability to keep iron in plant-available form, even in alkaline soils with high pH.

The 6% iron content refers to the amount of iron that is available for the plant to absorb.



Applications:

  • Agriculture (Iron Fertilizer):

  1. Iron Deficiency Correction: EDDHA Fe 6% is primarily used to correct iron deficiencies in plants, particularly in soils where iron chlorosis (yellowing of leaves) is common due to insufficient available iron.
  2. Highly Effective in Alkaline Soils: EDDHA is one of the most effective chelating agents for maintaining iron availability in alkaline soils (high pH), where iron typically becomes insoluble and unavailable to plants. This makes EDDHA Fe 6% particularly valuable in regions with alkaline or calcareous soils.
  3. Plants Benefiting from EDDHA Fe 6%: This product is used for a variety of crops, particularly those that are sensitive to iron deficiency, such as:
    • Citrus trees
    • Tomatoes
    • Peppers
    • Corn
    • Soybeans
    • Ornamental plants (e.g., flowers, shrubs)

  • Application Methods:

  1. Soil Application: EDDHA Fe 6% is applied to the soil, where the EDDHA chelate keeps iron available to the plants, even in high pH or calcareous soils.
  2. Foliar Spray: Foliar application can also be used for quick iron absorption, especially when plants show immediate symptoms of chlorosis or iron deficiency.
  3. Fertigation: It can be applied through irrigation systems (fertigation), providing a steady supply of iron to plants.
  4. Hydroponics: In hydroponic systems, where nutrient solubility is crucial, EDDHA Fe 6% ensures that iron remains bioavailable to plants in water-based growing systems.
 

Key Benefits:

  • Prevents Iron Lock-Up: 

EDDHA ensures that iron remains available and soluble in alkaline soils (high pH), where other forms of iron might precipitate and become unavailable.

  • Stable and Long-Lasting: 

EDDHA Fe 6% has a high stability constant, which means it is more stable and resistant to changes in soil pH, ensuring prolonged availability of iron to plants.

  • Effective in a Wide pH Range: 

EDDHA is highly effective in soils with pH levels between 6 to 9, making it suitable for a variety of soil types, including alkaline and calcareous soils.

  • Preventing Chlorosis:

By ensuring a constant supply of iron, EDDHA Fe 6% prevents chlorosis and supports proper photosynthesis and plant growth.
 

Summary:

EDDHA Fe 6% is a chelated iron fertilizer that is used to correct iron deficiencies in plants. It contains 6% iron by weight, and the EDDHA chelate ensures that the iron remains soluble and available for plant absorption, even in alkaline soils with high pH where iron is often unavailable. It is applied through soil treatments, foliar sprays, fertigation, or in hydroponic systems to correct iron chlorosis and promote healthy plant growth.
