| Abstract: | A brief account is given of the development of a new process for the production of high analysis non homogeneous urea based compound fertilizers by fluidized granulation and the experimental work. The results show that monoammonium phosphate, diammonium phosphate, single superphosphate or triple superphosphate may be used as raw materials to produce urea based compound fertilizers and the nutrient content may be adjusted in line with the demand of the users. Urea based compound fertilizers made by spraying molten urea onto single or triple superphosphate granules can prevent hygroscopicity. |
