It adapts perfectly to drip irrigation, sprinkler irrigation, foliar spraying and hydroponic systems, with zero blockage risk for pipelines and nozzles.

Stable Activity in Acidic & Neutral Medium: Maintains stable molecular structure in pH 4.0–7.0 soil and nutrient solutions. No invalid precipitation or oxidation failure occurs, providing long-term and continuous available iron nutrition for crops, ideal for most conventional planting soil environments.

Core Physiological Regulation for Plants: As an essential component for plant chlorophyll synthesis and oxidase activation, EDTA-Fe effectively boosts photosynthesis, accelerates carbohydrate metabolism, repairs yellowing leaves, and promotes root development and robust seedling growth. It solves stunted growth, leaf fade and low vitality caused by iron deficiency.

Whole-Growth-Cycle Safety & Non-Phytotoxic: Ultra-low heavy metal impurities with mild and stable activity. It will not burn roots, scorch leaves or cause crop phytotoxicity, safe for seedling stage, flowering stage and fruiting stage. Fully compatible with organic and green planting systems.

Excellent Tank Mix Compatibility: Highly compatible with most neutral and acidic water-soluble fertilizers, amino acid fertilizers, humic acid fertilizers and pesticides. No flocculation, stratification or efficacy loss after mixing, reducing fertilization frequency and improving planting efficiency.

4. Our Advantages

Premium Fully Chelated Formula: Different from low-grade semi-chelated iron products on the market, our Iron EDTA achieves 99%+ chelation rate with zero free iron ions. It ensures uniform nutrient release and stable absorption, avoiding local phytotoxicity and uneven growth of crops caused by unchelated residual iron.

Professional Fertilizer Grade Additive: Specially customized for compound water-soluble fertilizer, trace element fertilizer and hydroponic nutrient solution production. It features stable physical properties, good fluidity and strong formula compatibility, effectively improving the stability and market competitiveness of finished fertilizers.

Strict Full-Process Quality Control: Implements standardized management from raw material purification, secondary chelation reaction to finished product screening. Each batch is tested for iron content, chelation rate and solubility, with stable batch consistency and complete test reports for export.

Factory Direct Supply & High Cost Performance: Large-scale production base with sufficient spot inventory. Eliminate intermediate distributors to provide high-purity EDTA-Fe at competitive factory prices, supporting small-batch sample customization and large-batch bulk orders.

Professional Plant Nutrition Technical Support: Equipped with agricultural nutrition experts, providing targeted formula matching and fertilization solutions according to crop types, soil pH and deficiency symptoms, maximizing iron utilization efficiency and planting benefits.

Global Export Compliance: Meets EU, Southeast Asia, Middle East and other international fertilizer access standards, free of harmful residues. It is widely applicable for commercial crop planting and organic agricultural export projects with complete qualification certificates.

5. Application Scenarios

Iron EDTA is a versatile and high-efficiency trace element additive, widely used in fertilizer compounding, field planting, greenhouse cultivation and soilless culture scenarios:

Fertilizer Industrial Additive: Serves as the core iron source raw material for producing compound water-soluble fertilizers, foliar fertilizers, full-element trace element fertilizers and hydroponic nutrient solutions, improving fertilizer stability and nutritional balance.

Field Crop Planting: Suitable for wheat, corn, rice, cotton, peanuts and other field crops. Correct iron deficiency chlorosis, enhance photosynthetic efficiency, promote robust growth, and improve stress resistance and yield.

Fruits & Vegetable Cultivation: Applicable to citrus, grapes, apples, strawberries, tomatoes, cucumbers and other cash crops. Rapidly turns yellow leaves green, promotes branch and leaf growth, reduces physiological fruit drop, and improves fruit uniformity and taste.

Hydroponic & Greenhouse Agriculture: Ideal for soilless culture, greenhouse planting and indoor vegetable cultivation. It remains stable in nutrient solution without precipitation, ensuring continuous and balanced iron supply for facility crops.

Ornamental Plants & Turf Maintenance: Perfect for landscape flowers, seedlings, lawns and potted plants. Effectively improves leaf yellowing, sparse foliage and weak growth, maintaining lush plant appearance and high ornamental value.

6. Packaging & Transportation

Packaging Specification: Standard 25kg kraft paper bag with inner waterproof plastic lining; supports customized 1kg, 5kg, 10kg small packages and OEM private label packaging.

Storage Conditions: Store in a dry, cool and ventilated warehouse. Avoid long-term direct sunlight, high temperature and humid environment to prevent moisture agglomeration. Sealed storage after opening is required.

Transportation Requirements: Classified as conventional non-toxic and non-dangerous agricultural fertilizer raw materials, suitable for sea, land and air transportation. Do not transport and stack with strong alkaline substances to prevent structural damage and efficacy attenuation.

Shelf Life: 3 years under sealed, dry and normal temperature storage conditions, with stable physical and chemical properties and no fertilizer efficacy loss.

7. FAQ

Q1: What is the difference between EDTA-Fe and ordinary inorganic iron fertilizer?

A1: Traditional inorganic iron ions are easily fixed and invalidated by soil phosphate and calcium, with extremely low plant absorption rate and prone to cause local phytotoxicity. Our Iron EDTA adopts full chelation structure, which can stably exist in soil and water solution. It features higher activity, better stability and 10 times higher nutrient utilization rate, safely and efficiently solving crop iron deficiency problems.

Q2: What soil environment is Iron EDTA suitable for?

A2: EDTA-Fe is most stable and effective in pH 4.0–7.0 acidic and neutral soils. It is the preferred iron supplement for ordinary farmland, greenhouse soil and soilless nutrient solution systems, perfectly solving crop chlorosis and yellow leaf problems caused by insufficient available iron in conventional planting environments.

Q3: What are the core physiological functions of EDTA-Fe for crops?

A3: Iron is an essential micronutrient for plant photosynthesis and energy metabolism. EDTA chelated iron can significantly promote chlorophyll synthesis, restore leaf greenness, activate plant oxidase activity, enhance crop respiration and stress resistance, delay leaf senescence, and ultimately improve crop yield and quality.

Q4: Can Iron EDTA be mixed with other fertilizers and pesticides?

A4: Yes. It has excellent compatibility with all neutral and acidic water-soluble fertilizers, organic fertilizers and conventional pesticides. Mixing can improve fertilization efficiency. It is forbidden to mix with strong alkaline products to avoid destroying the chelated molecular structure and reducing fertilizer efficacy.

Q5: Is Iron EDTA suitable for hydroponic soilless cultivation?

A5: Absolutely. EDTA-Fe dissolves completely in water without precipitation, and will not react with other nutrient elements in the hydroponic solution. It can provide long-term stable available iron for hydroponic crops, avoiding iron deficiency yellowing and growth stagnation, which is a necessary trace element additive for facility agriculture.

Q6: Can it be used as a raw material for commercial compound fertilizer production?

A6: Yes. This fertilizer-grade Iron EDTA features stable chemical properties, good fluidity and strong formula adaptability. It will not react with nitrogen, phosphorus, potassium and other medium and trace elements, effectively improving the nutritional activity and added value of finished commercial fertilizers.
