Ammonium nitrate (NH₄NO₃) - ammonium nitrate is one of the most widely used nitrogen fertilizers, containing 34.4% total nitrogen in two forms:
- nitrate (NO₃⁻) — rapidly absorbed by plants immediately after application;
- ammonium (NH₄⁺) — retained in the soil, providing a prolonged release effect.
Recommended use:
- for all agricultural crops: cereals, industrial crops, vegetables, and forage crops;
- for base application, pre-sowing, top dressing, and fertigation;
- especially effective on crops that require a high initial dose of nitrogen with prolonged action.
Advantages:
- fast-acting and long-lasting nitrogen availability;
- suitable for spring start-up, intensive in-season feeding, and fertigation;
- highly soluble — can be used in liquid form;
- high nitrogen concentration — lower application rates, higher efficiency;
- versatile — compatible with all modern plant nutrition systems.
Limitations and warnings:
- do not apply to dry soil without moisture — risk of partial nitrification “burn”;
- do not mix with crop protection products (CPPs) without compatibility testing;
- avoid storing near heat sources, open flames, or flammable materials;
- potentially explosive under overheating or contamination — follow all storage regulations carefully.
Appearance and color: crystalline powder or white granules with a yellowish tint, free from foreign mechanical impurities.
| Mass fraction of nitrogen, % | 34,4 |
| Mass fraction of water, % | 0,2 – 0,3 |
| Granulometric composition, % | |
| Mass fraction of granules from 1 to 4 mm | 95 |
| Mass fraction of granules from 2 to 4 mm, not less | 80 |

- Store in dry, well-ventilated facilities, protected from direct sunlight, with relative humidity not exceeding 70%, keep on pallets, at least 15 cm above the floor, in a single row
- Packaging (sacks, big bags) must be sealed airtight to prevent moisture penetration;
- Permissible storage temperature: from –20 °C to +35 °C (avoid exposure to high humidity to prevent caking and condensation, loosen the product before use if caking occurs);
- Avoid contact with acids, alkalis, organic compounds, and other reactive fertilizers;
- During long-term storage, periodically loosen the material;
- Do not store near flammable materials, acids, alkalis, oils, or organic fertilizers. (Keep at least 5 meters away from heat sources or open flames)
Guaranteed shelf life: guaranteed storage period is 12 months from the date of manufacture, if transported and stored properly. After this period, the fertilizer should be tested for compliance with technical standards before use. Ammonium nitrate is classified as a potentially explosive substance under certain conditions. Strict adherence to storage safety rules is mandatory. Keep away from ignition sources.
