Abstract:

The important direction of fertilizer development in the 21st century is on slow/controlled release fertilizers which are of great significance to maintain China’s food security, improve the utilization rate of fertilizers, and realize the coordinated development of agricultural production and ecology. Meanwhile, slow/controlled release fertilizers can save cost and energy, and increase efficiency and reduce emissions. Based on the summary of the definition, action mechanism and research status of slow/controlled release fertilizers, we expounded the application effects of slow/controlled release fertilizers in agricultural production and the existing problems in their popularization and application. Then we put forward some corresponding countermeasures and suggestions. Finally, the development prospects of slow/controlled release fertilizers were discussed. The results will provide a theoretical basis for the study on slow/controlled release fertilizers.

Key words: Slow Release Fertilizer, Controlled Release Fertilizer, Fertilizer Utilization Rate, Food Security, Energy Conservation and Emission Reduction
