Abstract: Farmers use the manure waste to fertilize the fields to reduce it. An important disadvantage of the use of this waste as a fertilizer is the odor emitted and, in the absence of the possibility to plow the soil immediately after the application of the fertilizer, the reduction of useful substances. As a result, granulation of organic manure waste is becoming increasingly popular. Farmers use centrifugal spreaders of mineral fertilizers to spread these pellets in the soil, and due to the different properties of mineral and organic granular fertilizers, different uniformity of pellet spreading is obtained. The aim of the research was to investigate the spreading parameters of granular manure compost fertilizers in the soil by centrifugal spreading using computer simulation. For the simulation was proceeded by using EDEM software, Solid works software. Fertilizer spreader technical and physical and fertilizers physical parameters were set to proceed the simulations of the process. For the simulation, the operating parameters were selected according to the spread rate of the fertilizer, the working width of the fertilizer spreader, the uniformity of fertilizer spreading for the spreading of granular cylindrical bulk particles. The obtained results showed that it is expedient to apply computer simulation to study the spreading of fertilizers in the soil. In summary, fertilizer application studies can be very time consuming and expensive, a simulation model is being developed to reduce these costs, simulating the spreading process of organic granular fertilizers and determining the influence of particle rolling speed and spread rate on spreading uniformity
