High-Volume Soluble Manganese for Hydroponic, Fertigation & Soil Programs

Tecmangam Manganese Sulfate Soluble Powder is Prince Agri's commercial-scale water-soluble manganese source — delivering 32% manganese (Mn) and 18% sulfur (S) in a fine powder that dissolves completely for use in hydroponic nutrient solutions, fertigation systems, and foliar programs. The 55 lb bag is sized for high-volume operations that need a reliable, cost-effective manganese input at scale.

Manganese is essential for photosynthesis, enzyme activation, and nitrogen metabolism. Deficiency causes interveinal chlorosis in young leaves and reduced plant vigor — particularly in high-pH or leached soils. Tecmangam corrects it fast, with immediately plant-available Mn in every application.

Guaranteed Analysis

• Total Manganese (Mn): 32%
• Water Soluble Manganese (Mn): 32%
• Sulfur (S): 18%
• Derived from: Manganese Sulfate Monohydrate (MnSO₄·H₂O)

Application Rates

• 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
• Foliar: 1–3 lb/acre dissolved in water
• Soil broadcast: 20–60 lb/acre pre-plant or at planting for manganese-deficient soils
• Banding / side-dress: 10–30 lb/acre for in-season correction

Key Features

• 32% manganese — high-analysis, fast-acting soluble Mn source
• 100% water soluble — fully dissolves for hydroponic, fertigation, and foliar use; no clogging of injectors or emitters
• Dual nutrient — delivers manganese and sulfur simultaneously
• 55 lb commercial bag — high-volume size for greenhouse, nursery, and wholesale operations
