EDDHA Fe High Purity

1. Introduction

High Purity EDDHA Fe is a professional, high-stability organic chelated iron fertilizer specially developed for agricultural iron deficiency correction. As a top-grade soil and foliar iron supplement, it features ultra-high chelation rate, excellent pH adaptability and superior biological activity, solving the common problems of low absorption, easy fixation and poor effect of traditional inorganic iron fertilizers and ordinary EDTA iron products.

Different from low-purity EDDHA Fe on the market, our high-purity EDDHA Fe adopts advanced precise chelation synthesis technology, with ultra-high ortho-ortho (O-O) isomer content and 100% water solubility. It stably provides available iron elements for crops in extreme soil environments (pH 4.5–9.0), effectively improves iron deficiency chlorosis, yellow leaf disease and stunted growth of fruits, vegetables, field crops and ornamental plants. Widely applicable to drip irrigation, foliar spraying, soil base application and compound fertilizer processing, it is the preferred high-efficiency iron fertilizer for modern precision agriculture worldwide.

2. Specifications

All specifications comply with international agricultural fertilizer standards, with strict impurity control and stable batch consistency, meeting global bulk export and fine fertilizer production requirements.

3. Product Detail

Our high purity EDDHA Fe is a refined organic chelated iron product processed through secondary purification and precise chelation reaction with high-purity raw materials. Different from ordinary industrial-grade EDDHA Fe with mixed isomers and high impurities, this premium-grade product features uniform molecular structure, ultra-high active isomer content and zero insoluble impurities, which is the core guarantee of high-efficiency iron supplementation for crops.

In terms of product performance, high-purity EDDHA Fe can firmly chelate iron ions to form stable macromolecular compounds. It will not be fixed and invalidated by calcium, magnesium, carbonate and other substances in alkaline soil, and can freely penetrate crop root cell walls and leaf stomata. It solves the stubborn iron deficiency problems that cannot be improved by traditional iron fertilizers, and effectively repairs crop yellowing, leaf scorch, weak growth and low fruit setting rate caused by iron deficiency.

In terms of application scenarios, this product is universally suitable for cash crops (citrus, grapes, apples, strawberries, vegetables), field crops (wheat, corn, cotton) and ornamental plants. It supports multiple application methods including soil drenching, foliar spray, drip irrigation and fertigation, and can also be used as a high-quality raw material for compound trace element fertilizers, fully meeting the diversified production and planting needs of agricultural distributors, fertilizer factories and large-scale farms.

4. Features

Ultra-High Purity & Active Isomer Content: Premium purification process ensures 99%+ chelation rate and O-O isomer value up to 4.8%+, far higher than ordinary industrial-grade products. The active iron utilization rate is hundreds of times that of inorganic iron fertilizer and dozens of times that of EDTA iron, with faster and more lasting effect.

Full pH Adaptability & Extreme Soil Resistance: Stably effective in pH 4.5–9.0 soil, perfectly solves the pain point that iron fertilizer is easy to fail in alkaline and calcareous soil. It is not affected by soil salinity and hard water quality, suitable for global complex planting soil environments.

100% Water Soluble & Zero Residue: Superfine 200-mesh powder design, completely soluble in water without precipitation and residue. It will not block drip irrigation pipes and spray nozzles, compatible with all modern agricultural irrigation and fertilization equipment.

High Biological Availability & Rapid Effect: Chelated iron molecules are easily absorbed by crop roots and leaves. Obvious yellow leaf turning green effect can be seen in 3–5 days, which quickly restores crop photosynthesis, promotes growth, improves fruit quality and increases yield.

Stable Chemical Properties & Long Duration: Not easy to decompose, oxidize and lose efficacy. It can stay active in soil for a long time, realize one-time application and long-term iron supplementation, reduce fertilization frequency and save planting cost.

Safe & Environmentally Friendly: Low impurity formula, free of harmful heavy metals and toxic substances. It will not cause soil compaction and crop phytotoxicity, conforms to international organic agricultural planting standards and global fertilizer export regulations.

6. Q&A

Q1: What is the difference between high-purity EDDHA Fe and ordinary EDDHA Fe?

A1: Ordinary EDDHA Fe has low O-O isomer content, high impurities and unstable efficacy, while our high-purity EDDHA Fe has O-O isomer ≥4.8%, chelation rate ≥99%, zero insoluble impurities and more stable activity. It has better effect in alkaline soil, higher crop absorption rate and longer lasting efficacy, which is a professional grade for high-end agricultural planting and fine fertilizer production.

Q2: Is EDDHA Fe suitable for all soil types?

A2: Yes. Our high-purity EDDHA Fe adapts to pH 4.5–9.0 soil, covering acidic soil, neutral soil, alkaline soil and calcareous soil. It is especially suitable for alkaline soil where ordinary iron fertilizers are easy to fail, and solves the global common problem of crop iron deficiency chlorosis in alkaline planting areas.

Q3: What are the main application methods and dosage?

A3: It supports foliar spray, soil application, drip irrigation and fertigation. For foliar spraying, dilute 1000–1500 times with water; for soil application, 100–200g per plant for fruit trees, 150–300g per mu for field crops. The dosage can be adjusted appropriately according to crop type and iron deficiency degree, with no phytotoxicity in safe dosage range.

Q4: Can EDDHA Fe be mixed with other fertilizers and pesticides?

A4: Yes. It can be mixed with most neutral and acidic water-soluble fertilizers, pesticides and foliar fertilizers, with stable properties and no antagonistic reaction. It is not recommended to mix with strong alkaline pesticides and fertilizers to avoid affecting fertilizer efficacy.

Q5: What is the shelf life and storage method?

A5: The shelf life is 3 years in sealed state. It should be stored in a dry, cool and ventilated warehouse, avoiding direct sunlight and damp environment. Sealed storage after opening is recommended to prevent moisture agglomeration.

Q6: Do you provide samples and customized services?

A6: Yes. We provide free small-batch sample testing service, and support customized particle size, purity, packaging and OEM processing. We can also provide targeted fertilization solutions according to customers' planting crops and soil conditions.
