Abstract: | Slow/controlled released fertilizers (SRFs/CRFs) have been paid more attentions by the researchers in recent years. In this paper, the authors summarized the application effects and methods of SRFs/CRFs both at home and abroad, and focused on the he application effects on crops, soil and environment. Comparing with the common fertilizers, SRFs/CRFs can increase fertilizer use efficiency ,crop yield and quality, improve soil physical character and nutrient availability,, promote crop growth, and reduce environmental pollution. |
