N2  - Different forms of natural rubber were used for coating prilled urea for developing a slow release fertilizer. The technique involved incorporation of prilled urea at high loading into skim rubber, ISNR 5 and reclaimed rubber using an internal mixer. The highly urea filled rubber was then extruded and granulated. These granules were evaluated for volatilization loss, leaching and slow release characteristics. The results indicated that NR-encapsulated urea has the characteristics of a slow release fertilizer
