Fast-Acting Soluble Manganese & Sulfur in a Resealable 20 lb Pail

Prince Agri / Tecmangam Manganese Sulfate Monohydrate is a fine powder delivering 32% manganese (Mn) and 18% sulfur (S) in a 100% water-soluble formula — packaged in a resealable hard plastic pail for clean, precise dispensing and moisture-free storage. Suitable for hydroponic, fertigation, foliar, and soil applications, it corrects manganese deficiencies quickly across a wide range of crops and growing systems.

Manganese is essential for photosynthesis, enzyme activation, and nitrogen metabolism. Deficiency causes interveinal chlorosis in young leaves and reduced plant vigor. This fast-acting powder delivers immediately plant-available Mn right where it's needed.

Guaranteed Analysis

• Total Manganese (Mn): 32.0%
• Water Soluble Manganese (Mn): 32.0%
• Sulfur (S): 18%
• Derived from: Manganese Sulfate Monohydrate (MnSO₄·H₂O)

Application Rates

• Soil broadcast: 20–60 lb/acre pre-plant or at planting for manganese-deficient soils
• Banding / side-dress: 10–30 lb/acre
• Foliar: 1–3 lb/acre
• Hydroponic stock solution: Dissolve 0.9–1.0 g per liter of water; apply at 2.5 mL/liter (9–10 mL/gallon) to achieve ~1.5 ppm Mn in working solution
• Constant-feed systems: Target range 0.1–2.0 ppm Mn in nutrient solution

Key Features

• 32% manganese — high-analysis, fast-acting source of plant-available Mn
• 100% water soluble — fully dissolves for foliar, fertigation, and hydroponic use
• Fine powder — rapid dissolution with minimal agitation; no clogging of injectors or emitters
• Resealable hard plastic pail — screw-top lid keeps contents dry between uses; stackable and easy to store
• 20 lb size — ideal for small-to-mid scale operations, trials, and growers who prefer smaller pack sizes
