Granular chemical-grade ammonium sulfate ((NH₄)₂SO₄) is a high-purity nitrogen-sulfur fertilizer produced through controlled chemical synthesis.It contains 21% nitrogen (ammonium form) and 24% sulfur (sulfate form). This fertilizer stands out for its exceptional purity, stable composition, and absence of heavy metals, making it suitable even for greenhouse use and complex fertilizer blends. Due to its high granule strength, the fertilizer is ideally suited for mechanical application with all types of spreaders. It has a uniform particle size distribution and remains free-flowing under proper storage conditions

Recommended use:

  • all agricultural crops: cereals, legumes, oilseeds, vegetables, forage crops;
  • especially effective for sulfur-demanding crops: rapeseed, soybeans, mustard, garlic, onion;
  • base application, localized in-row placement, pre-sowing application;
  • on sulfur-deficient soils, for crops with increased sulfur demand;
  • suitable for blending with other fertilizers (after compatibility testing).

Advantages:

  • high chemical purity — ideal for sensitive crops and controlled environments;
  • uniform application — ideal for modern agricultural machinery;
  • improved crop quality — higher protein, gluten, and oil content;
  • long-lasting nitrogen effect and enhanced sulfur uptake;
  • low phytotoxicity — safe for young plants;
  • effective even under adverse weather conditions.

Limitations and warnings:

  • do not store near acids, alkalis, or organic fertilizers;
  • do not mix with lime-based or calcium fertilizers without prior compatibility testing;
  • avoid moisture exposure — may cause caking.

Appearance and color: irregular-shaped granules, color ranges from white to dark brown

Mass fraction of nitrogen in terms of dry matter, not less, % 19
Mass fraction of fraction larger than 0.5 mm, % 80
Mass fraction of fraction smaller than 6 mm, % 100
Mass fraction of insoluble residue in water, not more than % 0,5
  • store in dry, well-ventilated facilities, protected from direct sunlight, with relative air humidity not exceeding 70%. Place bags on pallets at least 15 cm above the floor, arranged in a single layer;
  • packaging (bags, big bags) must be tightly sealed to prevent moisture ingress;
  • permissible storage temperature: from –20 °C to +35 °C (avoid exposure to high humidity, as this may cause caking or condensation — loosen before use if necessary);
  • avoid contact with acids, alkaline substances, organic compounds, or other fertilizers that may cause a chemical reaction;
  • in case of prolonged storage, periodically loosen the product to prevent clumping.
Storage guarantee period: 1 month from the date of manufacture, provided that transportation and storage conditions are met. After this period, the product must be tested for compliance with technical specifications before use.
