General characteristics
UAN-30 is a liquid mineral fertilizer containing 30% of total nitrogen in three forms: nitrate (NO₃-) - quickly absorbed by plants but easily lost with water; ammonium (NH₄⁺) - slowly absorbed, less washed out; amide (NH₂) - converted to ammonium in the soil and prolonged effect and 1% sulfur in the form of sulfate (SO₃). This balanced composition provides phased nitrogen nutrition at all stages of the growing season and additional sulfur supply. UAN-30 is a good compromise between nitrogen concentration and reduced risk of phytotoxicity when applied foliarly. It is suitable for basic, pre-sowing and vegetative fertilization of cereals, corn, industrial and vegetable crops. The fertilizer is completely water-soluble, does not contain solid particles, does not form sediment and does not clog nozzles. It has a neutral or slightly alkaline reaction (pH ~ 7), does not acidify the soil, and is suitable for boom sprayers, drip irrigation systems and fertigation.Application:
- The main application is with soil incorporation;
- pre-sowing application;
- vegetative fertilization - especially effective in the phase of tillering, growth, and formation of generative organs;
- foliar application - in concentrations up to 10%;
- fertigation - in irrigation systems for vegetables and field crops.
Limitations and warnings:
- apply in the morning or evening, avoiding high temperatures;
- do not apply to wet foliage without prior dilution;
- crystallization temperature: -9 °C;
- precipitation or partial crystallization may occur at temperature extremes.
Appearance: Light yellow liquid with a characteristic odor of its components.

- store in tightly sealed containers (eurocubes, corrosion-resistant tanks, or rain-protected reservoirs);
- optimal storage temperature: +5 °C to +25 °C;
- in case of freezing, UAN-30 retains its properties — thorough mixing is required after thawing;
- Prevent contamination with foreign matter (soil, pesticides, water, etc.);
Storage guarantee period:The shelf life of the fertilizer, provided that transportation and storage conditions are observed, is 6 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.
Prohibited practices: do not overheat (above +40 °C); do not store near open flames or under extreme temperature fluctuations; do not pour into sewage systems or open water — follow applicable environmental disposal standards.
