Why Chelated Micronutrients?

Micronutrients are required in small quantities, but shortages can restrict crop development, quality and yield. Chelation binds a nutrient ion within an organic ligand, helping to keep the nutrient in a soluble and usable form under suitable application conditions.

Efficient nutrient delivery

Chelated forms can improve micronutrient availability and are widely used where iron, zinc, manganese, copper and other trace elements need targeted supplementation.

Flexible application

Products may be selected for soil incorporation, fertigation, hydroponic systems or foliar programmes according to the chelate, crop and growing conditions.

Rapid dissolution

Free-flowing soluble grades are suited to preparation of stock solutions and tank mixes, subject to compatibility testing and the directions on the final product label.

Selecting the right chelate

EDTA is widely used for several micronutrients. DTPA offers stronger iron chelation around neutral to moderately alkaline conditions, while EDDHA-type iron chelates are particularly useful in alkaline and calcareous soils.

Typical Applications

Arable crops

Fruit and orchards

Vegetables and protected crops

Ornamentals

Hydroponics and soilless culture

Fertigation programmes

Fertiliser manufacture and blending

Emerald Single-Element Chelates

Proposed Emerald product naming is based on the nutrient and declared analysis. Final specifications, chelation percentage and regulatory declarations should be confirmed against the material actually supplied before commercial printing.

Emerald Multi-Micronutrient Blends

Balanced blends can simplify micronutrient programmes by combining several trace elements in one soluble product. The formulations below are proposed equivalents based on the technical analyses supplied in the reference material; they should be verified against Emerald Chemicals’ final sourcing specifications.

Choosing the Appropriate Chelate

Chelate selection should take account of the target element, crop, growing medium, irrigation water and pH. The table below is a general technical guide rather than a product-use recommendation.

Chelating system	Typical role	General strengths	Considerations
EDTA	Fe, Zn, Mn, Cu and other micronutrients	Versatile; widely used in foliar and fertigation programmes	Performance depends on metal and pH
DTPA	Especially iron	Useful around neutral to moderately alkaline conditions and in some hard-water systems	Check formulation-specific stability range
EDDHA-type	Iron	High stability for iron in alkaline/calcareous soils	Generally selected for soil/root-zone iron correction
