Product Detail
EDTA Chelated Micronutrients
EDTA-Zn, EDTA-Fe, EDTA-Cu, EDTA-Mn, EDTA-Ca, EDTA-Mg, and EDDHA-Fe soluble micronutrient grades. Assays are typical for evaluation and confirmed per batch COA.
RunziChem is a Chinese manufacturer and exporter of EDTA chelated micronutrient fertilizer, based in Zouping, Shandong, and shipping FOB, CFR, or CIF from Qingdao port to distributors, fertilizer brands, and formulators in more than 50 countries. The range covers seven single-element grades — EDTA-Zn 15%, EDTA-Fe 13%, EDTA-Cu 14.5%, EDTA-Mn 13%, EDTA-Ca 10%, EDTA-Mg 6%, and EDDHA-Fe 6% (ortho-ortho 4.8%) — plus two compound all-element blends that deliver the full trace-element set in one water-soluble powder. Because each metal ion is held inside a chelate ring, these grades stay dissolved instead of fixing in soil or reacting in the spray tank, so they suit alkaline and calcareous soils, drip fertigation, foliar spraying, hydroponics, and water-soluble fertilizer manufacturing. Every shipment is documented with a TDS, the current batch COA, and an SDS; listed assays are typical values, and the batch COA confirms the final analysis.
What it is / When to use
What are EDTA chelated micronutrients?
EDTA Chelated Micronutrients cover zinc, iron, copper, manganese, calcium, magnesium, and EDDHA iron routes for buyers who need trace elements that stay soluble and formulation-ready. RunziChem also supplies a compound, all-element chelate blend that delivers the full micronutrient range in one water-soluble product.
- What it is EDTA chelated micronutrient range and EDDHA iron.
- When to use Use this range for foliar, drip, hydroponic, water-soluble fertilizer, and compound-fertilizer raw material programs where chelation helps nutrient availability.
- Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.
THE RANGE
Which EDTA grades does RunziChem manufacture?
Single-element EDTA chelates, high-pH EDDHA-Fe, and a compound all-element blend — each available factory-direct with COA/TDS/SDS.
EDTA-Zn — Zinc EDTA Chelate
EDTA-Zn is a stable, fully water-soluble zinc chelate in which the zinc is held in chelated form, protecting it against fixation in the tank and in soil. It is used as a raw-material additive in foliar, fertigation and compound micronutrient fertilizers.

EDTA-Fe — Iron EDTA Chelate
EDTA-Fe is a fully water-soluble iron chelate that delivers readily available iron to crops through fertigation, foliar spray and soilless systems. It is a practical route to correct iron chlorosis across a wide range of soils.

EDTA-Cu — Copper EDTA Chelate
EDTA-Cu is a fully water-soluble copper chelate that keeps copper plant-available across a wide pH range. It corrects and prevents copper deficiency through foliar spraying and fertigation.
View details →
EDTA-Mn — Manganese EDTA Chelate
EDTA-Mn is a fully water-soluble chelated manganese fertilizer supplying 13% Mn in a stable, plant-available form. It is designed for foliar sprays and fertigation to prevent and correct manganese deficiency across a wide range of crops.
View details →
EDTA-Ca — Calcium EDTA Chelate
EDTA-Ca is a stable, fully water-soluble calcium chelate that keeps calcium available to the plant across a wide pH range. It supports calcium nutrition in fruit trees and field crops through foliar, fertigation and soil applications.
View details →
EDTA-Mg — Magnesium EDTA Chelate
EDTA-Mg is a fully water-soluble, chelated source of magnesium for crop nutrition. The stable EDTA chelate keeps magnesium plant-available across a wide range of conditions, making it a reliable input for correcting and preventing magnesium deficiency.

EDDHA-Fe — Iron EDDHA Chelate
EDDHA-Fe 6% is a fully water-soluble iron chelate that keeps iron plant-available where sulphate and EDTA-Fe break down. It is the reference correction for lime-induced iron chlorosis in high-pH and calcareous soils.

Compound EDTA — Chelated All-Element Micronutrient Blend
A single fully-chelated product that delivers the complete set of trace elements in one water-soluble powder. Chelated forms resist soil fixation and are efficiently taken up by the plant.
