Organic Fertilizer Manufacturer & Supplier in India

Bulk Supply Range

Chelated Micronutrients That Stay Available

Central Biotech manufactures a complete range of EDTA chelated micronutrients for bulk supply, fertigation systems and export. EDTA chelation locks each nutrient in a stable, plant-available form, so it resists precipitation and stays available to the crop even in high-pH and problem soils where unchelated micronutrients get locked up.

The range covers single-element chelates of Zinc, Iron, Calcium, Copper, Manganese and Magnesium, plus specialty formulations including Calcium EDTA with Boron, EDTA and amino acid chelated micronutrient mixtures, micronized Zinc Oxide SC and Liquid Calcium. Multiple grades are notified by various State Governments of India.

High Chelation Value

Chelation values above 99.5%, and above 99.97% for Zinc EDTA, ensure superior stability, absorption and nutrient efficiency.

Complete Solubility

Highly water soluble with clean, complete dissolution and no residue left behind in the tank.

Drip System Safe

No precipitation and no clogging in drip irrigation systems, making the range dependable for modern fertigation.

Multiple Notified Grades

Our mixtures are manufactured in multiple grades notified by various State Governments of India for wide domestic distribution.

Bulk & Private Label

Manufactured at scale in 25 kg bags and 200 litre drums for bulk users, formulators and export or private label buyers.

Frequently Asked Questions

What does EDTA chelation actually do? +

EDTA wraps around the micronutrient ion and holds it in a stable, protected form. Without chelation, nutrients like iron, zinc and copper react with other elements in the soil or spray tank and become locked up in forms the plant cannot absorb. Chelation keeps the nutrient soluble and available for root and leaf uptake.

Why does chelation value matter? +

The chelation value tells you what proportion of the micronutrient is genuinely chelated and therefore protected. Our range carries chelation values above 99.5%, and above 99.97% for Zinc EDTA. A higher value means better stability, less precipitation and more of the nutrient actually reaching the plant.

Are these products safe for drip irrigation systems? +

Yes. All our EDTA chelated micronutrients are highly water soluble and dissolve completely without residue. They do not precipitate or clog drip systems, which makes them well suited to fertigation and modern precision irrigation.

What grades and packing are available? +

Single-element chelates and mixtures are generally supplied in 25 kg HDPE paper laminated bags, while Zinc Oxide 39.5% SC and Liquid Calcium 11% are supplied in 200 litre HDPE drums. Our micronutrient mixtures are available in multiple grades as notified by various State Governments of India.

Can I use these products in high-pH or limy soils? +

This is exactly where chelated micronutrients earn their value. In high-pH or limy soils, unchelated micronutrients get fixed and become unavailable to the crop. EDTA protects the nutrient and keeps it mobile and available to the roots.

Do you supply EDTA chelated micronutrients in bulk for export? +

Yes. The full range is manufactured for bulk supply, export and private labelling. Contact our team with the element, grade, quantity and packing you need and we will share specifications and commercial terms.
