Fine-Mesh Granular Zinc Sulfate for Faster Soil Incorporation

Maximo 361 Mini-Granule is Zinc Nacional's smaller-particle granular zinc sulfate monohydrate — the same high-analysis formula as the Maxi-Granule 363, but in a finer -16 +40 mesh size that breaks down faster in soil and blends more uniformly with other dry fertilizers. Delivering 35.5% zinc minimum and 17.5% sulfur, it's built for growers who need precise zinc correction with faster availability and cleaner blending performance.

When zinc is limiting, growth stalls at the cellular level — hormone production, chlorophyll synthesis, and carbohydrate metabolism all suffer. Maximo 361 gets zinc into the root zone quickly, with a granule size optimized for both broadcast application and dry blend compatibility.

Nutrient Analysis

• Zinc (Zn): 35.5% minimum
• Sulfur (S): 17.5%
• Lead (Pb): 0.01% maximum
• Iron (Fe): 1.00% maximum
• Cadmium (Cd): 0.01% maximum
• Chlorine (Cl): 1.00% maximum
• Fineness: -16 +40 mesh

Application Methods

• Broadcast & incorporate: Apply pre-plant or at-plant; till or irrigate in for rapid root-zone availability
• Dry blend: Mini-granule size compatible with blended fertilizer programs; mixes uniformly with other granular inputs
• Side-dress: In-season application alongside rows for targeted zinc correction
• General agriculture: Vegetables, fruit crops, grains, ornamentals, and specialty crops on zinc-deficient soils

Key Features

• -16 +40 mesh fineness — finer particle size than Maxi-Granule 363; faster breakdown and more uniform soil distribution
• Dry blend compatible — consistent granule size integrates cleanly into custom fertilizer blends
• 35.5% zinc minimum — high-analysis; efficient zinc delivery per pound applied
• Dual nutrient — zinc and sulfur in every granule; addresses co-occurring deficiencies in a single pass
• Commercial 50 lb bag — sized for farm, nursery, and wholesale operations
