Description

1. The coating ratio of *0days Polymer Coated Urea drop down to 2.4% and the content of nitrogen is up to *5.3% which is the highest of the world.
2. Initial release rate of nitrogen is less than 1%（*5℃，*4h）
3. Flexibility of release periods from *0 to **0 days at*5℃.
4. Polymer coating is very smooth and uniform with no breaks or cracked material which would allow uncontrolled release of nutrients.
5. Uniform particle size allows easier and precise mechanical distribution.
6. Release curve into sigmoid type, consistent with the crop absorption of nutrients.
