Usage:
As a foliar fertilizer and compound fertilizer raw materials In addition to single-element EDTA chelates, it also offers physical mixes (blends) or compounds (chemical mixes). For physical mixes, macro-nutrients and/or additives like amino acids and humic acids can be added.
Why EDTA Zn for Crops?
Zinc is essential for plant enzyme activity, chlorophyll synthesis, and auxin production. EDTA Zn delivers zinc in a chelated form that remains soluble and available to plants across a soil pH range of 4–7, outperforming inorganic zinc sulfate in uptake efficiency. Key uses include:
- Foliar spray: Rapid correction of zinc deficiency symptoms (stunted growth, small leaves) in corn, rice, and fruit crops.
- Fertigation: Compatible with NPK solutions and most water-soluble fertilizers for drip irrigation use.
- Compound fertilizer manufacturing: Added to NPK granules or liquid blends to provide micronutrient fortification.
- Hydroponics: Stable chelated zinc for soil-less growing systems where pH control is precise.
Unifarm Chemical supplies EDTA Zn with 15% chelated zinc content, in 25 kg bags or 1,000 kg big bags. We also offer custom blends of multiple EDTA micronutrients. Contact us for bulk pricing.
