Considering the prospects of using organic sapropel as a raw material for fertilizers in agriculture, particularly in organic farming, its processing becomes an extremely important step. Traditional organic fertilizers, such as manure, are produced virtually untreated using a fairly simple technology, and their quantity is limited by the number of animals. The quality of sapropel-based fertilizers depends on the content of the organic part, the processing method, and the characteristics of the deposit. An analysis of the existing research has shown that sapropel-based fertilizers can be single-component and multi-component. In addition, the content of organic matter in such fertilizers varies widely. Many studies have been devoted to the production of granular sapropel fertilizers and the processes of forming and drying independent particles of arbitrary size and shape, the formation of large balls and strands by pressing, the formation of particles in the form of plates, cylinders, etc. But, given the design features of bulk fertilizer machines, it is necessary to strive for the formation of granules in the form of a ball. The paper proposes directions for the use of sapropel in the production of single-component and multicomponent granular fertilizers. The design of machines for the production of granular sapropel fertilizers in the form of balls with an equivalent diameter of 2-6 mm is presented. The results of experimental studies on the strength, fractional composition, volume, and unit density of granules produced in laboratory conditions are also presented. The obtained results demonstrate the feasibility of implementing the development in production conditions and suggest directions for improvement.
