EDDHA Fe

High-Purity Chelated Iron + Alkaline Adaptation: Special Biostimulant for Efficient Iron Supplementation

EDDHA chelated iron (Fe 6.12%, core advantage) features a chelation rate of ≥99%, alkaline property at pH 8.69, and 200-mesh reddish-brown powder form. With a stable chelate structure, it achieves deep synergy of “high-activity chelation + stable efficacy in alkaline conditions + universal adaptation”, avoiding the disadvantage of ordinary iron fertilizers being easily fixed in soil. It integrates multiple functions: rapid iron supplementation, chlorosis correction, photosynthesis improvement, and good compatibility for blending. Suitable for all iron-demanding crops, especially solving iron deficiency in alkaline soils, it is the preferred product for efficient iron supply.

1. Mutual Enhancement: Chelation Activity & Absorption Synergy Adopting high-end chelation technology to form stable EDDHA-iron complexes, ensuring 6.12% EDDHA chelated iron content and ≥99% chelation rate. Iron exists stably in divalent form and can be directly absorbed without root conversion. The 200-mesh reddish-brown powder has fine particle size and excellent dispersibility, spreading quickly in water or soil. With pH 8.69 alkalinity, it prevents precipitation with phosphate ions in soil, completely solving the problems of easy fixation and low bioavailability of common iron fertilizers. It realizes dual enhancement of “chelation locking + efficient absorption” to meet the core demand of high bioavailability.

2. Alkaline Adaptation: Universal Soil Compatibility Product pH stably at 8.69, adapting to alkaline soil (pH 7.0–9.0) and absorbable by crops in pH 3–12 range, with extremely strong compatibility. It thoroughly solves the industrial problem that iron ions are easily fixed and hard to absorb in alkaline soils, greatly expanding applicable soil types. The 200-mesh powder penetrates evenly into all soil layers, stably supplying iron in alkaline fields, orchards, and greenhouse substrates, optimizing iron availability and adapting to diverse planting scenarios.

3. Efficient Iron Supply: Chlorosis Correction & Photosynthesis Enhancement 6.12% high-content EDDHA chelated iron is quickly absorbed to precisely supplement iron. As a key raw material for chlorophyll synthesis, iron effectively corrects iron-deficiency chlorosis, increases leaf chlorophyll content, and boosts photosynthetic efficiency to restore crop growth. Compared with ordinary iron fertilizers, it acts faster and lasts longer, significantly improving yellowing leaves and stunted growth caused by iron deficiency, strengthening physiological activity and laying a foundation for high yield and quality.

4. High Compatibility: Blending-Friendly & Universally Adaptable Excellent compatibility allows mixing with most water-soluble fertilizers, pesticides, and other chelated micronutrients (zinc, manganese, magnesium) without antagonism or precipitation, synergistically improving overall efficacy. Alkaline pH 8.69 fits most alkaline planting systems without extra pH adjustment. Suitable for foliar spray, drip irrigation, and fertigation, adapting to large-scale fields and intensive fruit/vegetable/flower cultivation to meet iron needs of various crops.

5. Quality & Efficiency Improvement: Broad Adaptation & Cost Optimization Suitable for fruits, vegetables, flowers, field crops and all iron-demanding plants, especially iron-sensitive crops such as citrus, rose, corn, vegetables. It prevents iron-deficiency chlorosis and improves crop quality and yield. 200-mesh reddish-brown powder enables accurate weighing, storage and transportation, not easy to caking. With high chelation rate, it achieves “low dosage, high effect”, reduces waste, significantly improves fertilizer use efficiency, balancing iron supply effect and planting cost.

Expert Advice: Especially suitable for alkaline soils and iron-deficient crops, particularly iron-sensitive fruits, vegetables and flowers. Can be used alone or blended with conventional fertilizers via foliar spray, drip irrigation or fertigation. 200-mesh powder dissolves completely without clogging pipes. Best applied at early chlorosis or key growth stages for better iron supply. Adjust dosage as needed to avoid over-application, realizing precise iron supplementation, quality improvement and income increase.
