Urea (CO(NH₂)₂) is a high-concentration nitrogen fertilizer containing 46% nitrogen in amide form (NH₂) — the highest nitrogen content among solid mineral fertilizers. Amide nitrogen gradually mineralizes in the soil, first converting into ammonium (NH₄⁺) and then into nitrate (NO₃⁻) form. This ensures slow-release, stable plant nutrition without nitrogen shock.

Recommended use:

  • suitable for cereals, oilseeds, industrial crops, forage crops, vegetables, root crops, fruit trees, berry bushes, flowers, and lawns
  • Base application with soil incorporation;
  • pre-sowing application;
  • top dressing during vegetation (in granulated or dissolved form);
  • foliar feeding (as a 5–10% aqueous solution);
  • fertigation after complete dissolution.

Advantages:

  • highest nitrogen content among mineral fertilizers;
  • slow-release effect reduces nitrogen losses and ensures prolonged feeding;
  • versatile usage: soil, foliar, and drip application;
  • high solubility — ideal for fertigation;
  • compatible with micronutrients, stimulants, and pesticides (after compatibility testing).

Limitations and warnings:

  • do not apply on the soil surface without incorporation — risk of nitrogen loss due to NH₃ volatilization;
  • do not exceed foliar feeding rates — risk of leaf burn;
  • tank mixes must be tested for compatibility before use;
  • highly hygroscopic — strict adherence to storage conditions is critical.

  • 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: the shelf life of the fertilizer, provided that transportation and storage conditions are observed, is 12 months from the date of manufacture. After the expiration of the guaranteed storage period, the fertilizer must be tested for compliance with technical specifications before use.
