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

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

Key Features

• 13% chelated manganese — high-analysis EDTA chelate; efficient Mn delivery at low use rates
• pH stable 3–10 — outperforms sulfate forms in alkaline conditions
• Fully water soluble — dissolves completely; no precipitates or injector clogging
• Resealable screw-top jar — keeps contents dry; easy to measure and store
• 1 lb size — ideal for home growers, small systems, and product trials

State restrictions: Not available for shipment to Oregon.
