Main advantages
About this product
UAN-28 — a liquid nitrogen fertilizer containing 28% total nitrogen in three forms: nitrate for immediate uptake, ammonium for stable soil nutrition and amide for prolonged action after mineralization. The reduced concentration compared with UAN-32 lowers the risk of burns during foliar feeding and increases efficiency under limited moisture. The fertilizer is fully water-soluble, does not form a sediment, and crystallizes only at minus 17 degrees, which simplifies storage and transport in the cool period. It is applied before sowing, during the growing season, with sprayers, by fertigation or by drip irrigation.
