EDTA-Chelated Manganese for Hydroponic, Fertigation & Foliar Use

Manganese EDTA 13% is a fully water-soluble chelated manganese fertilizer delivering 13% manganese (Mn) 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 manganese sulfate may lose availability at higher pH levels.

Manganese is essential for photosynthesis, enzyme activation, and nitrogen metabolism. EDTA chelation keeps Mn in a plant-available form across a pH range of 3–10 — critical in alkaline irrigation water or high-pH growing media where unchelated manganese rapidly becomes unavailable.

Guaranteed Analysis

• Manganese (Mn): 13% chelated with EDTA
• pH stability range: 3–10
• Target range in nutrient solution: 0.5–2.0 ppm Mn

Application Rates

• Hydroponic / constant-feed: Use at rates to achieve 0.5–2.0 ppm Mn 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

• 13% chelated manganese — high-analysis EDTA chelate; efficient Mn delivery at low use rates
• pH stable 3–10 — remains plant-available across a wide solution pH range; outperforms sulfate forms in alkaline conditions
• 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.
