EDDHA-Chelated Iron Fertilizers – Formulation & Production Guide

The EDDHA-Chelated Iron Fertilizers Formulation Book is an advanced manufacturing guide developed for fertilizer producers seeking to formulate high-stability iron chelate fertilizers for alkaline and calcareous soils.

EDDHA-chelated iron (Fe-EDDHA) fertilizers are specifically designed to supply iron in a highly stable chelated form that remains available to plants even in high-pH soil conditions. Unlike conventional iron salts or EDTA chelates, Fe-EDDHA provides superior stability and long-lasting micronutrient availability, making it the preferred solution for severe iron chlorosis management.

This book provides commercially viable formulations for 6% Fe high ortho-ortho grade, 4.8% Fe grade, liquid concentrates, granular soil-application grades, and water-dispersible powder export formulations, structured for both small and industrial-scale production.

 Agricultural & Industrial Applications

EDDHA-Chelated Iron fertilizers are widely used in:

• Calcareous and alkaline soils

• Orchard and plantation agriculture

• Vineyards and citrus production

• Greenhouse and protected cultivation

• Drip irrigation and fertigation systems

• High-value crop production

• Export-oriented fertilizer manufacturing

Fe-EDDHA is especially critical where soil pH limits iron availability and traditional iron fertilizers fail to correct chlorosis effectively.

 Designed for Small & Industrial-Scale Manufacturing

This guide supports production across multiple operational levels.

✔ Small-Scale Production Units

 Why EDDHA-Chelated Iron Is in High Demand

Iron chlorosis is one of the most widespread micronutrient deficiencies in alkaline soils. Fe-EDDHA fertilizers provide:

• Superior stability at high soil pH

• Long-lasting iron availability

• Reduced nutrient fixation

• Improved crop greening and vigor

• Reliable performance in orchards and high-value crops

As alkaline soil cultivation expands globally, demand for EDDHA-Chelated Iron fertilizers continues to grow in both domestic and export markets.
