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 4 lb size is ideal for small commercial operations, greenhouse growers, and multi-system nutrient programs.
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
