EDTA-Chelated Zinc for Hydroponic, Fertigation & Foliar Use

Zinc EDTA 15% is a fully water-soluble chelated zinc fertilizer delivering 15% zinc (Zn) complexed with EDTA for broad pH stability and consistent plant availability. Formulated for precision micronutrient programs in hydroponic systems, fertigation lines, and foliar applications where zinc sulfate may lose availability at higher pH levels.

Zinc is essential for enzyme activation, protein synthesis, and carbohydrate metabolism. EDTA chelation keeps Zn in a plant-available form across a wide pH range — critical in alkaline irrigation water or high-pH growing media where unchelated zinc rapidly precipitates out of solution.

Guaranteed Analysis

• Zinc (Zn): 15% chelated with EDTA
• Target range in nutrient solution: 0.5–2.5 ppm Zn

Application Rates

• Hydroponic / constant-feed: Use at rates to achieve 0.5–2.5 ppm Zn in working solution; consult a qualified agronomist for crop-specific rates
• Foliar: Apply per label recommendations; use in accordance with guidance from a qualified individual or institution
• Fertigation: Compatible with most nutrient programs; verify compatibility before tank mixing

Key Features

• 15% chelated zinc — high-analysis EDTA chelate; efficient Zn delivery at low use rates
• Broad pH stability — EDTA chelation maintains zinc availability across a wide solution pH range
• Fully water soluble — dissolves completely; no precipitates or injector clogging
• Precision dosing — ideal for growers running tight micronutrient programs in recirculating systems
• 20 lb pail — resealable container for easy handling and storage

State restrictions: Not available for shipment to Oregon.

Use in accordance with recommendations of a qualified individual or institution. See SDS for safety handling information.
