TECHNICAL DATA SHEET
UREA AMMONIUM NITRATE PRODUCT DESCRIPTION
 The UREA/AMMONIUM NITRATE (UAN) solution is created
UAN Fertilizer Solution 32% by dissolution of the amide and nitrate salt in water. It may have a slight ammonia odor. Approximately 35% UREA blended with 45% AMMONIUM NITRATE makes a fertilizer
 solution that is 32% nitrogen by weight. SDS
 Properties #1138 APPLICATION RECOMMENDATIONS
 • The lowest salt-out temperature possible for UAN 32 is 32oF at a ratio of 1.30 AMMONIUM
 Total Nitrogen % by weight minimum 32 NITRATE to UREA. Urea % by weight typical 40.9 to 31.2 • UREA is used as a slow release fertilizer. It must be decomposed by microorganisms
 Amine Nitrogen from Urea 19.1 to 14.5 before it can be assimilated by plants. The AMMONIUM NITRATE is the fast release part
