UAN 30+1S is a liquid mineral fertilizer that contains 30% total nitrogen in three forms:
- nitrate (NO₃⁻) – rapidly absorbed by plants but easily leached;
- ammonium (NH₄⁺) – slower uptake, less prone to leaching;
- amide (NH₂) – gradually converted in soil into ammonium form, ensuring prolonged action.
Application:
- base application — in spring or autumn (into moist soil before pre-sowing cultivation);
- topdressing — at the tillering, budding, and active growth stages;
- pre-sowing application — with mandatory incorporation into the soil or in combination with other fertilizers;
- foliar feeding — at reduced concentration;
- fertigation — especially effective in vegetable production and intensive farming systems.
Limitations and warnings:
- apply early morning or late evening, avoiding high temperatures;
- do not apply to wet foliage without prior dilution;
- crystallization temperature from 0 °C.
Appearance: Light yellow liquid with a characteristic odor of its components.
| Density, g/cm³ | 1,307 – 1,322 |
| Alkalinity, % | 0,05 – 0,5 |
| Mass fraction of ammonium nitrate, % | 40 – 49 |
| Mass fraction of urea, % | 35 – 40 |
| Mass fraction of water, % | 24 – 11 |
| Mass fraction of total nitrogen, % | 31 – 33 |
- store in hermetically sealed containers (eurocubes, corrosion-resistant tanks, or rain-protected reservoirs);
- optimal storage temperature: +5 °C to +25 °C;
- short-term drops to +1 °C are acceptable, but crystallization may occur below 0 °C;
- if frozen, the product can be thawed without quality loss — ensure uniform heating and stirring;
- prevent contamination with foreign matter (soil, crop protection products, pesticides, water);
- do not discharge into sewage systems or open water bodies — disposal must comply with environmental regulations;
Keep away from open flames or heating elements.
Guaranteed shelf life: when stored and transported under proper conditions, the product remains usable for 6 months from the production date. After the expiration of the guaranteed storage period, the fertilizer must be tested for compliance with technical requirements before use. UAN-32 is not an explosive or flammable product. It is safe for storage and transportation when standard handling instructions are followed.

Note: Apply UAN when the air temperature does not exceed +15...+18 °C. Application should be done after sunset, as droplets during daytime may act as lenses and burn the leaf tissue. Do not apply during rain or when plants are wet with dew. Use large droplets to avoid leaf burn.
