UAN-32

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.

This balanced composition ensures gradual and effective nitrogen nutrition throughout the entire growing season.

The product is fully water-soluble, free of solid particles or sediment, and does not clog nozzles. With a neutral to slightly alkaline pH (~7), it is safe for the soil and compatible with boom sprayers, drip irrigation, and fertigation systems.

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.

• 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;

Avoid storage under extreme temperature fluctuations (may cause separation or crystallization);
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.

Note: UAN-32 is non-flammable and non-explosive. The product is safe to handle and transport when standard safety practices 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.
