Granular Zinc Sulfate for Soil Application — Built for Field & Specialty Crops

Maximo 363 Maxi-Granule is Zinc Nacional's granular zinc sulfate monohydrate, engineered for direct soil incorporation and broadcast application. Delivering 35.5% zinc minimum in a uniform, dust-free granule, it's the practical choice for field growers and specialty crop operations that need a reliable, easy-to-handle zinc source without the mess of fine powder.

Zinc deficiency limits growth hormone production, chlorophyll synthesis, and carbohydrate metabolism. Maximo 363 corrects it at the root zone — where it counts most — through slow, consistent release as the granule breaks down in soil moisture.

Nutrient Analysis

• Zinc (Zn): 35.5% minimum
• Sulfur (S): 17.5%

Application Methods & Rates

• Broadcast & incorporate: Apply pre-plant or at-plant to zinc-deficient soils; till or water in for best results
• Side-dress: Apply alongside rows during the growing season for in-season correction
• Pre-plant soil amendment: Establish baseline zinc levels before transplant in zinc-deficient fields
• General agriculture: Suitable for vegetables, fruit crops, grains, and ornamentals where soil zinc is limiting

Key Features

• Maxi-granule format — uniform, dust-free granules for clean, easy handling and spreading
• 35.5% zinc minimum — high-analysis formula; more zinc per pound than lower-grade products
• Dual nutrient — delivers zinc and sulfur simultaneously to address co-occurring deficiencies
• Soil-safe — no chlorine; won't contribute to salt buildup or chloride toxicity
• Commercial 50 lb bag — sized for farm, nursery, and wholesale use
