Abstract

To enhance the effectiveness of urea fertilizers, a new coated slow-release fertilizer was developed using Aswan Red Clay (ARC) and a binder material called chitosan a biodegradable polymer was used to improve the property of urea. Characterizations of slow release of the urea granules were made using Scanning Electron Microscopy technique and energy dispersive X-ray analysis. Refractive Index method used for determine the rate of releasing. Ammonia volatilization was estimated by using the forced-draft technique. The static release experiment showed that the urea coated by Aswan Red Clay (ARCCU) gave a release of 9.78% at the first day and 95.36 at 24 day, in the same condition. The results of ammonia that volatized  during 6 weeks showed that the total losses of ammonia gas for uncoated urea( UCU) and coated urea was 59.54% and 43.33%, respectively which main that the coating of urea is most costly in application.
