Urea ammonium nitrate solution (UAN solution) is liquid nitrogen fertilizer containing 28-32% of nitrogen. UAN solution is a high-performance fertilizer, equal to ammonium nitrate or urea regarding influence on agricultural crops yield increase. UAN solution is produced by mixing water solutions of urea and ammonium nitrate in determined proportions with neutralization of free ammonia and inhibition of the product derived. UAN contains practically no free ammonia; this fact excludes nitrogen loss in loading, transportation, storage and application in soil. UAN may be applied using high-performance machines excluding simultaneous filling in soil, and also with sprayed water.
Main technical characteristics
|Total Nitrogen, %, min||32|
|Urea/Ammonium Nitrate ratio,%||0.74 -0.8|
|Alkalinity in terms of free ammonia, %||0.02-0.1|
|Content of inhibitor, %, min||0.01|
|Type of inhibitor||Novocor and/or Corblok|
UAN contains a corrosion inhibitor for the protection of carbon steel equipment. Chemicals allowed for application in accordance with established procedure are used as corrosion inhibitor.
UAN with corrosion inhibitor may be transported in rail tank cars and truck tanks. Low crystallization temperature -2°С and chilling temperature -26°С allow transportation and storage of UAN year-round, especially in buried concrete and asphaltic heated storages, film-lined inside. Crystallization and short-term freezing of UAN solution in storage tanks are not very dangerous, since crystals are dissolved and fertilizers fully restore their properties with the rise of temperature.
Shelf life: 6 months from production date.
