Studies on nitrogen release dynamics of new coated ureas
Coated ureas (CUs: CU1, CU2) were made of normal granular urea by coating with organic polymer layers in different thickness. the nitrogen release rate of CUs were determined in lab under different conditions, The results obtained showed that: Coated ureas were all slow-release fertilizers.

| Summary: | Coated ureas (CUs: CU1, CU2) were made of normal granular urea by coating with organic polymer layers in different thickness. the nitrogen release rate of CUs were determined in lab under different conditions, The results obtained showed that: Coated ureas were all slow-release fertilizers. The thicker the polymer layer was, the slower its nutrient released; The ammonia volatilization and nitrogen leachate reduced from CUs compared with normal urea; The content of ions in the environment affected the release rate of nitrogen of CUs. |
