Potential of epoxidized natural rubber (ENR) as hydrophobicity contributor in chitosan-urea fertilizer
Abstract. This study is to investigate the potential of ENR to be incorporated with chitosan for slow release urea fertilizer. In this research, mixture of chitosan and epoxidized natural rubber (ENR) was used as binder to take advantage of their biodegradable and polar characteristics, respectively...
