Manganese Sulfate 31% Powder (50 lb)

Quick-Acting Source of Manganese

Manganese Sulfate 31% Powder (50 lb) is a fast-acting, highly soluble source of manganese formulated to correct soil deficiencies and support optimal plant growth. As an essential trace mineral, manganese plays a crucial role in photosynthesis, nitrogen metabolism, and disease resistance, making it a valuable input for high-performance agricultural practices.

Key Benefits:

  • High-Purity Formula: Contains 31% manganese and 18% sulfur for balanced plant nutrition.
  • Essential for Photosynthesis: Supports chlorophyll formation and oxygen production.
  • Boosts Crop Resilience: Strengthens cell walls and enhances disease resistance.
  • Rapid Deficiency Correction: Quickly addresses yellowing leaves and poor growth caused by manganese-deficient soils.
  • Versatile Application: Suitable for soil application, foliar sprays, or fertigation.
  • Cost-Effective for Large-Scale Use: Ideal for commercial farming and broad-acre operations.

Application Guidelines:

  • Soil Application: Apply 20–60 lbs per acre pre-plant or at planting.
  • Banding or Side-Dressing: Use 10–30 lbs per acre.
  • Foliar Spray: Apply 1–3 lbs per acre for rapid absorption.
  • Fertigation: Compatible with irrigation systems for uniform nutrient distribution.

The Role of Manganese in Plant Health:

  • Photosynthesis: Essential for chlorophyll formation and oxygen release.
  • Enzyme Activation: Enables plants to synthesize proteins and break down carbohydrates.
  • Nitrogen Metabolism: Improves nitrogen uptake and utilization efficiency.
  • Soil Health & Microbial Activity: Supports nutrient cycling and enhances soil fertility.

Best Uses:

  • Field Crops & Orchards: Provides consistent nutrient availability for high-yield production.
  • Greenhouses & Hydroponics: Supplies a soluble, readily available source of manganese for controlled environments.
  • Soil Amendment for High-pH Soils: Helps unlock nutrients in alkaline conditions.

Manganese Sulfate 31% Powder (50 lb) is an essential solution for large-scale growers seeking to correct soil deficiencies and maximize crop performance. With its high solubility and rapid uptake, it is both an effective and economical choice for sustainable agriculture.
