The main disadvantages of using granular nitrogen fertilizers are described. The advantages encapsulated organo-mineral fertilizers are presented. It is proposed to use suspension of chicken manure as an organic shell. One presents the experimental results of coating the carbamide granules with an organic shell in a fluidized bed apparatus. The operating and technological parameters of the encapsulation process in the fluidized bed apparatus have been determined. Analytical relationship for determining the weighted average diameter of suspended particle during the encapsulation process is proposed.

Keywords: fluidized bed; suspended layer; coefficient; time
