CHEMICAL INDUSTRY
Urea is a raw material forthe manufacture of twomain classes of materials:urea-formaldehyde resins and urea-melamine-formaldehyde used in marineplywood.
AGRICULTURE
More than 9O% of world industrial production of urea is destined for useas a nitrogen-release fertilizer.
Urea has the highest nitrogen con-tent of all solid nitrogenous fertilizersin common use.
Therefore, it has the lowest transpor-tation costs per unit of nitrogen nutri-ent.
Urea is a small diameter, spherical white solid. It is an organic amide molecule containing 46% nitrogen in the form of amine groups. UREA is infinitely soluble in water and is suitable for use as an agricultural and forestry fertilizer as well as for industrial applications which require a high quality nitrogen source.

Applications
1.Medical field
Dermatology uses certain agents containing urea to increase the humidity of the skin. Non-surgical removal of nails uses occlusive dressings that contain 40% urea.
2.Agriculture
Urea is a highly concentrated nitrogen fertilizer, which is a neutral fast-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and there are no adverse effects after long-term application. Animal husbandry can be used as feed for ruminants. However, if the temperature is too high in granulation, a small amount of biuret will be produced, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea biuret for fertilizer should be less than 0.5%. When the content of biuret is more than 1%, it can not be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and the urea content in other application periods should not be too much or too concentrated.
3.Industrial sector
It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, monosodium glutamate and other products.
4.Laboratory applications
Urea is very effective at denaturing proteins, especially non-covalently bonded proteins. This feature can improve the solubility of certain proteins at concentrations of up to 10 mol/volume. Urea can also be used to make urea nitrate.
Urea is one kind of neutral fertilizer, which can be used in long time without any
harmful material in soil. Usually it can be used both for base and top dressing
fertilizer in agriculture.
urea : Can be used in agriculture and producing BB fertilizer.

It is a white crystal and one of the simplest organic compounds. It is the metabolic decomposition of protein in mammals and some fish. The main nitrogen-containing end product is also the nitrogen fertilizer with the highest nitrogen content.As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, easy to use, and has little damage to the soil. It is a chemical nitrogen fertilizer that is currently used in a large amount. In industry, ammonia and carbon dioxide are used to synthesize urea under certain conditions.Agricultural applications:Urea is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of compound fertilizers. .Urea is an organic nitrogen fertilizer. After being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil, it can be absorbed and utilized by crops. Therefore, urea should be applied 4 to 8 days before the fertilization period of the crop.
