What is EDTA Ferrous?
EDTA Ferrous (Iron EDTA Chelate) is a chelated form of iron micronutrient fertiliser, in which iron ions are bound within the EDTA molecular structure to form a water-soluble complex that protects the iron from oxidation and precipitation that commonly occurs with non-chelated iron sources, particularly in neutral to mildly alkaline soil conditions. This chelation significantly improves the plant-availability and uptake efficiency of iron compared to inorganic iron salts.
Polychem Industries supplies EDTA Ferrous to agricultural input companies, fertiliser blenders, and horticultural suppliers across India and internationally. Iron is essential for chlorophyll synthesis and numerous plant enzymatic processes, and iron deficiency (often visible as interveinal yellowing known as iron chlorosis) is one of the most common micronutrient deficiencies in crops grown on calcareous or high-pH soils.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Agricultural Grade | Yellow to brown crystalline powder | Fe content 13–14% (chelated) | Agricultural / Fertiliser | Foliar sprays, fertigation, soil application, hydroponics |
Applications & Uses
Foliar Fertiliser Sprays
Widely used to rapidly correct iron deficiency symptoms, particularly the characteristic interveinal chlorosis seen in iron-deficient plants. Foliar application of EDTA Ferrous provides fast, visible greening response in affected crops.
Fertigation & Drip Irrigation
Used in fertigation systems for its excellent water solubility and chelate stability, ensuring iron remains available for plant uptake through drip irrigation systems without the clogging issues associated with non-chelated iron sources.
Soil Application in Calcareous Soils
Applied to soil in regions with calcareous or high-pH soils, where iron is naturally rendered unavailable to plants through precipitation as insoluble iron compounds, EDTA Ferrous maintains iron in a plant-accessible chelated form.
Fruit Trees & Citrus
Particularly important in citrus and other fruit tree production, where iron chlorosis is a common and economically significant issue affecting fruit yield, size, and quality, especially in calcareous orchard soils.
Hydroponics & Soilless Culture
Used as the standard iron source in hydroponic and soilless growing systems due to its stability and consistent plant availability, which is essential since plants in these systems rely entirely on the supplied nutrient solution for iron.
Ornamental & Landscape Plants
Used in nursery production and landscape maintenance to correct and prevent iron deficiency in ornamental plants, particularly species known to be susceptible to iron chlorosis in alkaline growing media or soil.
