Zusammenfassung:	A continuous method for making granules of methylene urea-isobutylene diurea (MU-IBDU) includes: injecting an MU-IBDU slurry including water and MU-IBDU particles into a fluid bed granulator, wherein the fluid bed granulator includes seed particles; injecting air into the fluid bed granulator to fluidize the seed particles in an air stream; spraying the MU-IBDU slurry over the fluidized seed particles to form granules of MU-IBDU; and removing the granules of MU-IBDU from the fluid bed granulator. Fertilizer compositions including the MU-IBDU granules are also described.
