Nitrogen Fertilizer Urea 46% N Prills Granular Controlled Release Urea Phosphate Type

Controlled release urea fertilizer is a type of urea fertilizer that maintains a longer fertilizer efficiency due to slow release of effective nitrogen caused by changes in chemical composition or surface coating with semi permeable or impermeable substances. The advantage is that after one application, it can meet the nutrient needs of crops for a period of time to adapt to their growth patterns. The main varieties include formaldehyde fertilizers, sulfur coated urea, etc.

Controlled release urea can be an important component of BB fertilizer, which can effectively control the release rate of nitrogen fertilizer when used, and its effect is much better than that of ordinary compound fertilizer.
Shangyi International's controlled release urea is the most advanced controlled release technology product in Chinese Mainland. It can be used as a single nitrogen element in combination with phosphorus and potassium fertilizer, and can also be used as the basic raw material of mixed fertilizer to produce BB fertilizer. Its effect can be guaranteed.
