Urea Fertilizer Granular Applications:
1. As fertilizer in agriculture: As a nitrogen-rich fertilizer, it is common used to crops. It is considered one of the most popular and economical sources of nitrogen for plants.
Urea Fertilizer Granular is suitable for use as a base fertilizer and topdressing, and sometimes as a seed fertilizer. Urea is a molecular state before conversion and cannot be adsorbed by soil, so it should be prevented from losing with water. The ammonia formed after conversion is also volatile, so urea should also be deeply coated. Urea is suitable for all crops and all soils, can be used as base fertilizer and topdressing, dry paddy fields can be applied. Due to the conversion of urea in the soil can accumulate a large number of ammonium ions, resulting in a PH increase of 2-3 units, coupled with urea itself contains a certain amount of biuret, its concentration at 500ppm, it will inhibit the crop roots and buds, so urea is not easy to use as seed fertilizer
2. Industrial use:
- It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, VAT brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate and other products.
- It has a brightening effect on the chemical polishing of steel and stainless steel, and is used as a corrosion inhibitor in metal pickling, and is also used in the preparation of palladium activation liquid
- Automotive urea selective catalytic reduction (SCR), SCR system is a necessary system to meet the stringent emission regulations of modern vehicles such as Euro IV/ Euro V/ Euro VI (Country IV/ Country V/ Country VI) regulations. Automotive urea is called AdBlue (adding blue liquid) in Europe, and DEF (diesel exhaust treatment liquid) in the United States.

Storage for Urea Fertilizer Granular:
1,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.
