The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
Urea phosphate is a 1:1 combination of urea and phosphoric acid that is used as a fertilizer. It has an NPK formula of 17-44-0, [ 1 ] and is soluble in water, producing a strongly acidic solution. Urea phosphate is available in fertilizer vendor bags that carry a UP signet on the packaging.
The second number ("P value") is the percentage by weight of phosphorus pentoxide P 2 O 5. The third number ("K value") is the equivalent content of potassium oxide K 2 O. [3] For example, a 15-13-20 fertilizer would contain 15% by weight of nitrogen, 13% by weight of P 2 O 5, 20% by weight of K 2 O, and 52% of some inert ingredient.
Ammonia comes in second with 36.1%. (0.73mtpa). Future projects, such as the Brunei Fertilizer Industries Brunei Urea Plant and the Brunei Fertilizer Industries Brunei Ammonia Plant, are expected to increase the complex's capacity (1.29mtpa). [8] The facility, which has a nameplate capacity of 3900mt per day. [9]

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.
