Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen. Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007). [28] The main straight phosphate fertilizers are the superphosphates:
The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate , 35% urea and only 20% water.
