Water Soluble Chelated Iron for Fertilizer Compounding & Alkaline Soil Chlorosis
EDDHA Fe Fertilizer is a high-stability, fully water-soluble chelated iron raw material, widely used for commercial crop iron supplementation and professional fertilizer formula compounding. With high-purity O-O isomer structure, excellent water solubility and superior compounding compatibility, it is the preferred functional additive for fertilizer manufacturers and the most effective solution for stubborn crop iron chlorosis.
Core Functions & Crop Growth Benefits
Iron is an indispensable micronutrient for plant photosynthesis, chlorophyll synthesis and enzyme metabolism. Regular application of EDDHA Fe brings comprehensive physiological improvements for crops:
Rapidly eliminates stubborn leaf chlorosis and leaf whitening, restoring dark green and vigorous foliage
Boosts chlorophyll production and dry matter accumulation to promote crop growth
Activates root metabolism, enhances nutrient absorption and improves crop stress resistance
Stabilizes flower bud differentiation, increases fruit setting rate, and improves fruit color, taste and commercial yield
Applicable High-Value Crops
Specially suitable for iron-sensitive commercial crops that are prone to chlorosis in alkaline soil areas:
Citrus Crops: Orange, lemon, grapefruit - relieves orchard yellowing and improves fruit gloss and sweetness
Berry & Vine Crops: Grape, strawberry, blueberry - promotes uniform coloring and sugar accumulation
Stone Fruits: Apple, peach, cherry - solves recurrent chlorosis and stabilizes annual yield
Ornamental Plants: Azalea, camellia, gardenia - maintains bright leaf color and prolongs flowering period
Vegetables, Turf & Hydroponics: Safe for greenhouse planting, soilless culture and all fertigation systems
Core Product Advantages (For Planters & Formulators)
Full pH Stability (4.0–10.0): Works efficiently in acidic, neutral and alkaline soil, making up for the high-pH failure defect of EDTA Fe
High Bioavailability: Active O-O isomer structure ensures low dosage, fast crop absorption and high nutrient utilization
100% Water Soluble: Fast dissolving, zero residue, no pipeline blockage, perfect for liquid fertilizer production and drip irrigation
Super Compatibility for Compounding: Stable to blend with NPK fertilizers, EDTA micronutrients and neutral pesticides, no precipitation or nutrient antagonism
Long-Lasting Efficacy: Provides 4–6 weeks of continuous iron supply, reducing fertilization frequency and production costs

FAQ | Frequently Asked Questions
Q1: Why is EDDHA Fe the best iron raw material for fertilizer compounding?
A1: EDDHA Fe owns ultra-stable chemical properties and outstanding compounding performance. It can be freely mixed with nitrogen, phosphorus, potassium, and other chelated micronutrients like EDTA Cu, EDTA Zn and EDTA Mn. No flocculation, precipitation, stratification or nutrient inactivation occurs after compounding. It perfectly upgrades the nutrition system of finished water-soluble fertilizers, foliar fertilizers and compound fertilizers, improving overall fertilizer efficiency and product market competitiveness.
Q2: Is EDDHA Fe completely water-soluble for liquid fertilizer production?
A2: Yes. Our EDDHA Fe is 100% fully water-soluble with rapid dissolving speed and zero insoluble impurities. The aqueous solution is clear and stable, not easy to oxidize and precipitate. It will not block filters, pipelines and drip irrigation equipment, fully meeting the production standards of high-end liquid fertilizers and hydroponic nutrient solutions.
Q3: Can compounded EDDHA Fe fertilizer be stored for a long time?
A3: Absolutely yes. Benefiting from the stable O-O isomer chelating structure, EDDHA Fe resists oxidation, photolysis and nutrient failure. Whether compounded in solid or liquid fertilizers, it can maintain long-term stable activity without efficacy attenuation, ensuring consistent quality of finished fertilizers during shelf storage.
Q4: What is the difference between EDDHA Fe and EDTA Fe for fertilizer production?
A4: EDTA Fe is only stable below pH 7.5 and completely fails in alkaline conditions, with poor compounding stability and low utilization rate. EDDHA Fe maintains stable activity in pH 4.0–10.0, adapts to all soil and water quality environments, and has stronger compounding compatibility. It is a high-end alternative to EDTA Fe, suitable for manufacturing high-quality full-nutrition compound fertilizers.
Q5: What application methods does EDDHA Fe support?
A5: With excellent water solubility, it supports diverse application scenarios including foliar spraying, soil drenching, root irrigation, drip irrigation, fertigation and hydroponic cultivation. It is suitable for both direct farm use and industrial fertilizer compounding production.
