Product details
Product: Urea
Related word: nitrogen for garden vegetables, urea is a organic fertilizer, Urea fertilizer for plants
Molecular formula:CH4N2O
Molecular weight：60.05
Properties: An organic compound composed of carbon, nitrogen, oxygen, and hydrogen is a white crystal. One of the simplest organic compounds is the main nitrogen-containing end product of protein metabolism in mammals and some fishes. It is also the nitrogen fertilizer with highest nitrogen content.
As a neutral fertilizer, urea is suitable for all kinds of soils and plants. It is easy to preserve, easy to use, the damage to the soil is small, is a large amount of current use of chemical nitrogen fertilizer. In industry, ammonia gas and carbon dioxide are used to synthesize urea under certain conditions
Â
Urea is used as a base fertilizer and topdressing, and sometimes as a seed fertilizer. Before the conversion of urea is molecular state, can not be adsorbed by the soil, should prevent with water loss.
Urea applies to all crops and all soil, can be used as base fertilizer and topdressing, dry paddy field can be applied.
Urea (nitrogen fertilizer) can promote the cell division and the growth, causes the branch leaf to grow luxuriantly. It can be used as raw material for melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, Caffeine, Reduced Brown Br, Phthalocyanine B, Phthalocyanine Bx, monosodium glutamate and other products.

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:Â No harmful substances remain in the soil, and long-term application has no adverse effects.
Â
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 ammonia 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.
