Product: Urea
Related word: nitrogen for garden vegetables, urea is a organic fertilizer, Urea fertilizer
Molecular formula:CH4N2O
Molecular weight:60.05
Properties: Urea is a white crystalline organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is considered one of the simplest organic compounds and serves as the primary nitrogen-containing end product of protein metabolism in mammals and certain fishes. With the highest nitrogen content among nitrogen fertilizers, it is widely used in agricultural applications.
As a neutral fertilizer, urea is suitable for various soils and plants. It offers easy preservation and application, causing minimal harm to the soil. As a result, it is one of the most extensively utilized chemical nitrogen fertilizers. In the industrial sector, urea synthesis involves the use of gas and carbon dioxide under specific conditions.
Applications: Urea finds application as a base fertilizer, topdressing, and sometimes as a seed fertilizer. Since urea initially exists in a molecular state that cannot be absorbed by the soil, precautions should be taken to prevent water loss.
Urea is suitable for all crops and soil types, making it appropriate for use as a base fertilizer and topdressing. It can also be applied in dry paddy fields.
The application of urea (nitrogen fertilizer) promotes cell division and growth, resulting in lush foliage and abundant branching. Additionally, it serves as a raw material for the production of various products, such as melamine, urea formaldehyde resin, Reduced Brown Br, Phthalocyanine B, Phthalocyanine Bx, monosodium glutamate, and others.

Storage:
1,If the storage of urea is improper, it is easy to absorb moisture and caking, which will affect the original quality of urea and bring some economic losses to farmers. Be sure to keep the urea bag intact before use, handle lightly during transportation, rain-proof, and store in a dry, well-ventilated place with temperature below 20 degrees.
2,If it is a large number of storage, the following to use wood pad up about 20 cm, the upper part and the roof to leave more than 50 cm of space, in order to facilitate ventilation and moisture, between the pile and pile to leave a corridor. For Inspection and ventilation. Already opened the bag urea if not used up, must seal the bag in time, in order to use next year.
Packing: 25/50KG woven bag lined with plastic bags, or according to the requirements of customers.

Q1: Will there be harmful substances in long-term use of this product?
A:No harmful substances remain in the soil, and long-term application has no adverse effects.
Q2: What should I pay attention to when using this product?
A: Urea is an organic nitrogen fertilizer, through the soil urease action, hydrolyzed into ammonium carbonate or ammonium bicarbonate, can be absorbed by crops. Therefore, urea should be applied 4 to 8 days before the crop needs fertilizer. This product can not be made seed fertilizer, seedling fertilizer and leaf fertilizer. Urea hydrolysis produces ammonium nitrogen, and surface application will cause volatilization, especially on alkaline soil. Therefore, urea should be applied deep in the soil, and the paddy field should be applied deep to the reducing layer.
