Sodium Ferric EDDHA丨CAS 16455-61-1

Sodium ferric EDDHA丨16455-61-1 is a chelating agent that is widely used in agriculture, particularly for the fertilization of plants. It is a complex of iron (Fe) and EDDHA (ethylene diamine-N,N'-bis(2-hydroxyphenylacetic acid)), a chelating ligand. This complex helps to supply iron to plants in a form that is easily absorbed, even under alkaline or high pH conditions, where iron typically becomes insoluble and unavailable to plants.

1. Agricultural Fertilizer (Iron Chelate)

Sodium ferric EDDHA is primarily used as a micronutrient fertilizer to provide iron to plants, particularly in soils that are alkaline or high pH, where iron is usually insoluble and unavailable for plant absorption. Iron is an essential nutrient for plants, as it plays a key role in photosynthesis and the formation of chlorophyll.

Iron Deficiency in Plants: One of the most common symptoms of iron deficiency in plants is chlorosis, where the leaves turn yellow due to a lack of chlorophyll. This condition is especially prevalent in calcareous (lime-rich), alkaline soils, where iron is locked in an insoluble form.

Sodium ferric EDDHA丨16455-61-1 Effectiveness: It is considered one of the most effective forms of iron chelate because it remains stable at a wide range of pH levels (pH 4 to 12), making it especially useful in soils with high pH or alkaline conditions.

2. Horticulture and Greenhouses

Sodium ferric EDDHA is extensively used in greenhouse cultivation and hydroponics where nutrient availability is critical for plant growth. Its ability to supply iron efficiently helps improve the growth and vigor of a wide variety of plants, including fruit trees, vegetables, flowers, and ornamentals.

3. Landscaping and Turf Management

In turf management, especially for golf courses, lawns, and sports fields, sodium ferric EDDHA can help revitalize grass and improve color. It is often used in liquid fertilizers for rapid application.

4. Soil Amendment for Iron Deficiency

For soil applications, sodium ferric EDDHA is used to amend iron-deficient soils. This is particularly important in regions with high lime content or alkaline soil conditions, where standard iron sulfate or iron chelate may not be effective.

5. Foliar Application

Sodium ferric EDDHA丨16455-61-1 is often applied foliar (directly to plant leaves), which allows for quick absorption of iron, especially in cases of acute iron deficiency.

Highly Effective Chelate for Iron: Sodium ferric EDDHA丨16455-61-1 is a highly stable complex that provides iron to plants, even in alkaline or high pH soils, where other forms of iron may be ineffective. It prevents the iron from forming insoluble compounds, ensuring its availability for plant uptake.

Wide pH Range: Unlike many other iron chelates, sodium ferric EDDHA is effective across a wide range of soil pH levels (pH 4 to 12). This versatility makes it useful in different soil types, especially those with high levels of calcium or lime.

Improved Plant Growth and Yield: Iron is crucial for the production of chlorophyll and plays a role in photosynthesis. By ensuring that plants receive adequate iron, sodium ferric EDDHA helps improve chlorophyll production, resulting in greener, healthier plants with better growth rates and higher yields.

Reduces Chlorosis: By addressing iron deficiency, sodium ferric EDDHA effectively reduces symptoms of chlorosis, especially in plants grown in alkaline soils.

Long-lasting Effect: Because of its stability and ability to persist in the soil, sodium ferric EDDHA offers long-term benefits for plants, reducing the need for frequent reapplication.

Sodium ferric EDDHA丨16455-61-1 is a highly effective iron chelate used to correct iron deficiencies in plants, especially in alkaline or high pH soils. It is widely used in agriculture, horticulture, and turf management to improve plant health, growth, and yield. Its ability to remain stable across a wide range of pH levels makes it one of the most versatile and effective forms of iron fertilizer. However, care should be taken to avoid over-application and ensure its responsible use to minimize any potential environmental impact.
