Recent trends in organic coating based on biopolymers and biomass for controlled and slow release fertilizers

The growth of the human population is causing an exponential increase in need for food. Fertilizers are one most important elements to meet this increased demand and ensure global food security. Many enhanced efficiency fertilizers, such as controlled-release fertilizers (CRFs) have been developed. Although these offer many advantages over prior generations, their high cost production well unfavorable effects on environment soil quality limited use. To mitigate issues, CRFs based biopolymers ([email protected]) represent a new generation produced by coating granules with biopolymers. In addition controlling nutrient release rate, products also enhance they reduce negative associated conventional fertilizers. This review summarizes recent advances derived used area [email protected], technologies, parameters governing behavior through organic materials, effect coated plants growth.
