Description
What is Zinc Sulphate Monohydrate Powder?
Zinc Sulphate Monohydrate Powder (ZnSO₄·H₂O) is a highly concentrated water-soluble zinc fertilizer containing ≥33% zinc (Zn) and ≤17% sulfur (S). Specifically processed into fine powder (80-100 mesh), it ensures rapid dissolution and optimal absorption for correcting zinc deficiency in crops. As an essential micronutrient, zinc activates critical enzymes for protein synthesis, auxin metabolism, and chlorophyll formation, directly influencing yield quantity and quality.
Core Features & Competitive Advantages
1. High Purity & Nutrient Efficiency
Zn ≥33%: Ultra-concentrated active zinc for 40% faster deficiency correction than heptahydrate forms.Low Chloride (<1.0%): Safe for chloride-sensitive crops (e.g., potatoes, citrus, beans).
2.Optimized Physical Properties
Fine Powder (80-100 mesh): 100% solubility within 60 seconds, leaving zero residue in irrigation systems.Low Moisture (≤0.5%): Prevents caking during storage and transport, even in humid climates.
3.Certified Quality & Safety
Heavy Metal Control: Pb≤10ppm, As≤5ppm (complies with EU 2019/1009 & OMRI standards).
Industry Certifications: ISO 9001, FAMI-QS for feed-grade applications.
Stability & Functionality
1.Superior Storage Stability
Hygroscopicity ≤3% (vs. 15% for heptahydrate): Maintains free-flowing properties for 24 months in sealed packaging.
Thermal Stability: Decomposition temperature >680°C, suitable for global shipping.
2.Agronomic Functionality
Root Development: Stimulates root elongation by 30% via auxin (IAA) activation.
Enzyme Activation: Essential for carbonic anhydrase and SOD enzyme synthesis, boosting stress resistance.

FAQ
Q1: Why choose granular over powder potassium sulphate?
A: Granular form reduces dust loss by 90% and enables uniform field coverage, critical for large-scale mechanized farming. Our granules’ hardness (40-50N) withstands bulk shipping, reducing logistics costs by 7% compared to powder.
Q2: Is the higher potassium sulphate price justified compared to MOP?
A: While initial cost is 20% higher, ROI comes from: (1) 15-20% yield premium for chloride-sensitive crops; (2) Reduced sulfur additive costs; (3) Elimination of salt damage risks. Cost per kg of harvest drops by $0.18.
Q3: Can this granular potassium sulfate be used in organic farming?
A: Yes, OMRI-listed (Cert ID: XXXXX) with heavy metals below EU 2019/1009 limits. Approved for USDA/NOP and EU ECOCERT systems.
