| Abstract: | In order to improve utilization of fertilizer and to reduce environmental pollution, nowadays controlled-release fertilizer has become a focus in fertilizer research in China and abroad. A systematic classification of slow and controlled release fertilizers and details about the mechanisms of nutrient release are given in this paper. The ecological, economic and environmental effects which are brought by application of slow and controlled release fertilizer are reviewed in this paper. Finally, the problems and directions in controlled release fertilizer production and practice are discussed. |
