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. No harmful substances remain in the soil, and long-term application has no adverse effects.Animal husbandry can be used as feed for ruminants. However, excessively high temperature in granulation will produce a small amount of biuret, also known as biuret, which has an inhibitory effect on crops.my country stipulates that the content of urea biuret used in fertilizers should be less than 0.5%. When the biuret content exceeds 1%, seed fertilizer, seedling fertilizer and foliar fertilizer cannot be used, and the urea content in other application periods should not be too much or too concentrated.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.

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.
