Slow/Controlled release fertilizer can be the premise of ensuring food production. It can improve nutrient utilization and reduce negative impact of fertilizer nutrient loss to the environment. Coated slow/controlled release fertilizer has better controlled release rate of nutrients. It can match crop nutrients need and fertilizer release rate through the formation of coating materials design. This paper reviews the coated slow/controlled release fertilizer research status
the controlled release mechanism and release properties evaluation methods of fertilizer nutrients. The existing problems and future development trends of coated slow/controlled release fertilizer research and application are also elaborated.
