Full explanation
UAN-32 is the most common grade at 32% N, density 1.33 kg/L (so 1 t = ~750 L). Advantages: precise application via nozzles, compatibility in tank mixes with crop-protection products and micronutrients (herbicide + micro + UAN), and band-row fertigation through knife injectors ('localized nutrition'). Requires specialized nozzles (slot-stream or drop-pipe splash plates) to minimize leaf burn — especially on winter wheat past BBCH 30. April 2026 price: UAH 13 500–15 500/t [VERIFY] (cost per kg N comparable to urea). Producers: OSTCHEM (Cherkasy Azot, Rivneazot). Trade-off: requires specialized equipment (corrosion-resistant tanks, acid-resistant pump seals), but offers logistics advantages (pipes vs bags) and tank-mixing compatibility with other liquid products.
