Brandt® Manganese Sulfate 31% EDTA Micronutrient Supplement — 50lb Powder

Brandt® Manganese Sulfate 31% EDTA Micronutrient Supplement — 50lb

Brandt® Manganese Sulfate 31% EDTA is a professional-grade micronutrient supplement delivering chelated manganese in a highly soluble powder form for both soil and foliar application in commercial growing operations. Manganese is an essential cofactor for photosynthesis, nitrogen metabolism, and enzyme activation — deficiency manifests as interveinal chlorosis on young leaves (a pattern visually distinct from iron deficiency), reduced photosynthetic efficiency, and diminished plant vigor in high-production growing environments.

The EDTA chelation maintains manganese in a plant-available form across a broad soil pH range, protecting against the rapid oxidation and precipitation that renders non-chelated manganese sulfate unavailable in alkaline soils and hydroponic solutions. At 31% manganese concentration, this formulation provides a highly economical source of corrective and preventive manganese nutrition for commercial growers managing large-scale production programs where micronutrient management directly impacts crop quality and yield consistency. Apply to actively growing plants just before leaf expansion for maximum uptake efficiency during periods of peak metabolic demand.

Key Features & Benefits

• 31% Chelated Manganese (EDTA) — High-concentration chelated form maintains manganese availability across soil pH ranges where non-chelated sources precipitate and become unavailable.
• Dual Soil & Foliar Application — Versatile application flexibility allows both preventive soil incorporation and rapid corrective foliar sprays for visible deficiency symptoms.
• Corrects Manganese Deficiency — Addresses interveinal chlorosis, reduced photosynthetic output, and impaired nitrogen metabolism caused by Mn deficiency in actively growing crops.
• 50lb Commercial Size — Bulk packaging provides economical manganese nutrition for large-scale commercial growing operations, greenhouse programs, and multi-crop production facilities.
• Apply Before Leaf Expansion — Timing applications to precede periods of rapid leaf development maximizes manganese incorporation into new tissue during peak uptake windows.

Who Should Use This

Commercial greenhouse growers, hydroponic facility managers, and large-scale crop producers managing crops in high-pH soils, alkaline irrigation water, or soilless media where manganese availability is frequently limited benefit from Brandt® Manganese Sulfate 31% EDTA as both a preventive program component and a corrective intervention when deficiency symptoms appear. The 50lb size is appropriate for operations applying manganese nutrition across multiple crop cycles or large growing areas.

Compatibility

Soluble powder — dissolve in water before application. Compatible with most fertilizer programs and irrigation water. Apply to soil or as foliar spray to actively growing plants just before leaf expansion. Perform a jar test before tank mixing with other nutrient concentrates. Store in a cool, dry location in the original sealed container.

Frequently Asked Questions

How do I distinguish manganese deficiency from iron deficiency?

Both produce interveinal chlorosis, but Mn deficiency typically appears on younger leaves first (tip of the plant), while Fe deficiency classically shows on the youngest emerging leaves. Soil or tissue testing provides definitive confirmation before applying corrective treatments.

What is the application rate for foliar manganese correction?

Foliar application rates vary by crop, growth stage, and deficiency severity. Consult Brandt's product label for recommended foliar dilution rates and follow re-entry and pre-harvest interval guidelines for your specific crop.

Can this be applied through drip irrigation systems?

Yes — the soluble powder dissolves fully in water and can be applied through drip irrigation and fertigation systems. Filter your irrigation system appropriately and avoid mixing with products that may cause precipitation before dilution into the main feed line.

Why use EDTA chelated manganese instead of standard manganese sulfate?

EDTA chelation protects manganese from oxidation and precipitation reactions in the soil and irrigation water, keeping it in a plant-available form across a wider pH range. Non-chelated manganese sulfate can rapidly become unavailable in neutral to alkaline conditions.
