Coated Urea Ch4n2o White Prilled
Urea (Carbamide/ Urea solution/ USP Grade Carbamide) is easy soluble in water and used as a neutral quick-released high concentration of nitrogen fertilizer, popular used in NPK compound fertilizers & BB fertilizers as a basic raw material, also can coated suphur or polymer as control-released fertilizer.
Long-term application of urea does not remain any harmful substances to the soil .But urea contains small amount of biuret in granulation process, when biuret content exceeds 1%, urea can not be used as seeling and foliar fertilizer.
Polymer-coated urea, also called plastic-coated urea, or PCU, fertilizers can permit a more precise rate of nitrogen release than sulfur-coated urea products. It's possible to produce polymer-coated products where the nitrogen release can be delayed for 10 months after application.
Following application, PCU granules start absorbing moisture that dissolves the nutrients inside the granules. The dissolved nutrients then diffuse, slowly and continuously, into the root zone.
The rate of diffusion – the actual release rate - depends upon and is dictated solely by the soil temperature. The release rate increases as temperature rises, just as happens with plant uptake rates.
Other factors, such as soil type, humidity, pH, and microbial activity do not affect the release rate.
