Abstract
With the increasing of public concern toward human health and environmental protection, there is a shift toward to develop a cofriendly fertilizer based on natural resources. In this study, a coated urea by different materials such as phosphate slimes (PCU), silica fume (SiCU), bentonite (BCU) with Chitosan as binder were created to enhance the slow release mechanism.    Characterizations of the coated urea were done using Scanning Electron Microscopy (SEM) with energy dispersive, X-ray analysis (EDX), Spectroscopy Fourier Transform Infra-Red (FTIR), refractive Index (RI) and Crushing Strength Test. The static release experiment showed that the (PCU), (SiCU) and (BCU) gave a release of 4.0, 4.7 and 4.9 % at the first day and 63.4, 74.0 and 82.7 after 30 days, in the same condition, respectively. Crushing Strength Test was carried out for the same size and showed that (PCU), (SiCU) and (BCU) overcame, the uncoated urea
