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

Chelated Manganese for Interveinal Chlorosis on New Growth

Yellowing between the veins on younger, tip leaves points to manganese deficiency, a distinct pattern from the similar-looking chlorosis caused by iron shortage. Brandt Manganese Sulfate 31% EDTA delivers chelated manganese in a form plants take up efficiently through either soil or foliar application, correcting the deficiency at its source rather than treating the wrong nutrient.

EDTA chelation binds the manganese in a stable structure that resists the oxidation and precipitation non-chelated manganese sulfate is prone to in alkaline soil conditions, keeping the nutrient plant-available across a wider pH range.

Key Features & Benefits

• 31% chelated manganese (EDTA) — concentrated, plant-available manganese in a stable chelated form.
• Corrects interveinal chlorosis — targets the yellowing pattern on younger, tip leaves specific to manganese deficiency.
• Dual application method — applies as either a soil treatment or a foliar spray.
• Stable across a broad pH range — EDTA chelation resists the oxidation and precipitation that affect non-chelated manganese in alkaline conditions.
• 50lb commercial bulk size — sized for larger-scale nutrient management programs.

Who Should Use This

Commercial growers managing manganese deficiency across larger growing areas, who need a chelated, pH-stable micronutrient source for soil or foliar programs, are the direct fit for this bulk size.

Frequently Asked Questions

How is manganese deficiency different from iron deficiency?

Both cause interveinal chlorosis, but manganese deficiency typically shows on younger, tip leaves, while iron deficiency also affects new growth but can present with a finer, more uniform yellowing pattern. Correctly identifying the nutrient before treating avoids wasted applications.

Why is EDTA chelation used for this product?

EDTA chelation binds the manganese ion in a stable molecular structure, protecting it from the oxidation and precipitation reactions that reduce availability of non-chelated manganese sulfate in alkaline soil. This keeps the nutrient plant-available across a wider pH range.

When should this product be applied?

Apply before leaf expansion for peak nutrient uptake, since manganese demand is highest during active new-leaf development. Later applications can still help but are less effective once leaves have fully expanded.

Can this be used with drip irrigation or fertigation systems?

Yes, it is compatible with drip irrigation and fertigation systems. Run a jar test with your specific tank mix before full-scale application to confirm compatibility with other products in the tank.
