Sewage sludge (50-52% moisture) of a large regional city in the western part of Ukraine is characterized by a complex of agronomically valuable traits, but their direct incorporation into the soil as a non-traditional organic fertilizer is ecologically impractical due to a number of unfavorable factors, therefore, they should be processed into quality fertilizers of the new generation. The composition of complex organo-mineral fertilizers based on sewage sludge with mineral additives of different origin is developed and new three- and two-component organo-mineral fertilizers of prolonged action for multi-purpose use are obtained. In a field experiment (2017-2019) with a comparative study of the effectiveness of different types of fertilizers in the fodder crop rotation, it was found that new organo-mineral fertilizers with the main application in optimal doses on light gray forest soil in the Western Forest-Steppe of Ukraine had the same effect in the year of action and aftereffects as traditional and non-traditional organic fertilizers, as well as complete mineral fertilizers (in equivalent doses), and allow with a single application of the first crop rotation crop to grow the second and third crops without fertilizers 110% and 45% according to the control without fertilizers.
