Manganese EDTA Chelate 13% Mn 20 lb

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
