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. Sold in a resealable screw-top jar — the 1 lb size is ideal for home growers, small hydroponic systems, and product trials.

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 & fertigation: Apply per label recommendations; use in accordance with guidance from a qualified individual or institution

Key Features

• 15% chelated zinc — high-analysis EDTA chelate; efficient Zn delivery at low use rates
• Broad pH stability — maintains zinc availability across a wide solution pH range
• Fully water soluble — dissolves completely; no precipitates or injector clogging
• Resealable screw-top jar — keeps contents dry; easy to measure and store
