UAN-30

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.
