Product Description:
More than 90% of world production of urea is destined for use as a nitrogen-release fertilizer.
Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use (46.7%).
Therefore, it has the lowest transportation costs per unit of nitrogen nutrient .

Many soil bacteria possess the enzyme, urease , which catalyzes the conversion of the urea molecule to two ammonia molecules and one carbon dioxide molecule,

thus urea fertilizers are very rapidly transformed to the ammonium form in soils.

Among soil bacteria known to carry urease, some ammonia-oxidizing bacteria (AOB), such as species of Nitrosomonas are also able to assimilate the carbon dioxide released by the reaction to make biomass via the Calvin Cycle , and harvest energy by oxidizing ammonia (the other product of urease) to nitrite, a process termed nitrification . Nitrite-oxidizing bacteria, especially, Nitrobacter , oxidize nitrite to nitrate, which is extremely mobile in soils and is a major cause of water pollution from agriculture. Ammonia and nitrate are readily absorbed by plants, and are the dominant sources of nitrogen for plant growth. Urea is also used in many multi-component solid fertilizer formulations.

Urea is highly soluble in water and is, therefore, also very suitable for use in fertilizer solutions (in combination with ammonium nitrate : UAN ), eg, in 'foliar feed' fertilizers. For fertilizer use, granules are preferred over prills because of their narrower particle size distribution which is an advantage for mechanical application.

The most common impurity of synthetic urea is biuret , which impairs plant growth.
