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°.
CF Industries Holdings, Inc. is an American manufacturer and distributor of agricultural fertilizers, including ammonia, urea, and ammonium nitrate products. The company is based in Northbrook, Illinois, a suburb of Chicago, [3] and was founded in 1946 as the Central Farmers Fertilizer Company.
Urea. Although urea has a number of industrial uses, these are dwarfed by the scale of its use as a nitrogen fertilizer.Urea has the highest nitrogen content (46 wt-%) of all the recognized solid nitrogen fertilizer materials and, from the early 1950s onwards, its use has continually increased, progressively displacing both ammonium sulphate, which was formerly the dominant product, and a ...
Urea (CO(NH 2) 2), with 45-46% nitrogen, another popular source of nitrogen, having the advantage that it is solid and non-explosive, unlike ammonia and ammonium nitrate. 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.

South Korean drivers are panic buying urea, an additive used in diesel vehicles to reduce emissions, after China tightened exports, prompting the president's office to set up a taskforce on Friday ...
The operator of Muara Port, MPC, is best equipped to handle the fertilizer shipments, according to BFI, which plans to export granular urea to far-off markets including India, Australia, Latin America, and the United States. [16] The company' new urea melt facility was successfully started up and is the biggest Stamicarbon has ever permitted. [9]
Nearly 97% of South Korea's urea imports came from China between January and September. In 2015, South Korea had made it mandatory for diesel cars to use urea solutions to control emissions, a move that now impacts 40% of registered vehicles. Diesel vehicles made since 2015 were required to be fitted with SCR systems. [28]
