Detailed
What is Zinc Sulphate Monohydrate Granular?
Zinc Sulphate Monohydrate Granular (ZnSO₄·H₂O) is a high-concentration zinc fertilizer processed into uniform 1-3mm granules, containing ≥33% zinc (Zn) and ≤17% sulfur (S). Designed for precision agriculture, it corrects zinc deficiency in crops through efficient soil or foliar applications. The granular structure ensures dust-free handling, enhanced flowability, and controlled nutrient release, making it ideal for mechanical broadcasting and blending with NPK fertilizers.
Core Features & Competitive Advantages
High Concentration & Dual Nutrients
• Zn ≥33%: 40% higher bioavailability than heptahydrate forms, ensuring rapid deficiency correction.
• S ≤17%: Synergistically enhances nitrogen assimilation and chlorophyll synthesis.
Optimized Granular Structure
• 1-3mm spherical granules: Anti-dust, compatible with mechanical spreaders, and resistant to wind drift.
• Low moisture (≤0.8%): Prevents caking during storage and maritime transport.
Quality & Safety Assurance
• Heavy metal control: Pb≤10ppm, As≤5ppm (compliant with EU 2019/1009).
• Chloride-free (<1.0%): Safe for chloride-sensitive crops (e.g., citrus, potatoes).
Stability & Functionality
Physical Stability
• Crush strength ≥30N: Withstands bulk handling and stacking without breakdown.
• Hygroscopicity ≤3%: Maintains free-flowing properties in humid climates (e.g., Southeast Asia).
Agronomic Functionality
• Root-zone zinc release: Gradual dissolution within 15 minutes, reducing leaching loss by 25%.
• Enzyme activation: Critical for carbonic anhydrase and auxin synthesis, boosting stress resistance.

FAQ
Why choose granular over powder zinc sulphate?
A: Granular form reduces dust loss by 90%, ensures uniform field coverage, and minimizes operational risks in humid conditions – critical for large-scale farming.
Q2: How does zinc sulphate monohydrate granular compare to EDTA-Zn?
A: Our granular zinc offers 30% higher cost-efficiency for soil applications, while EDTA-Zn is superior in high-pH soils (>7.5). Granular zinc provides slow-release benefits.
Q3: What is the recommended application rate for zinc-deficient crops?
A: Apply 5-10kg/acre based on soil test results. For severe deficiency, combine with foliar spray (0.2% solution) for rapid correction.
