EDTA-Chelated Copper for Hydroponic, Fertigation & Foliar Use

Copper EDTA 15% is a fully water-soluble chelated copper fertilizer delivering 15% copper (Cu) complexed with EDTA for maximum stability and plant availability across a wide pH range. Designed for precision micronutrient programs in hydroponic systems, fertigation lines, and foliar applications where copper sulfate may precipitate or lose availability.

Copper drives enzyme activation, photosynthesis, and lignin synthesis. At trace levels it's essential — but it's easy to over-apply. EDTA chelation keeps copper in a plant-available form at the low concentrations required in nutrient solutions, reducing the risk of toxicity while ensuring consistent uptake.

Guaranteed Analysis

• Copper (Cu): 15% chelated with EDTA
• Target range in nutrient solution: 0.01–0.1 ppm Cu

Application Rates

• Hydroponic / constant-feed: Use at rates to achieve 0.01–0.1 ppm Cu 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 copper — high-analysis EDTA chelate; efficient Cu delivery at low use rates
• Broad pH stability — EDTA chelation maintains copper 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.
