The realization of the rules of the precision agriculture is recently one of the main areas of the agriculture technology development. The precision agriculture system relies on the optimal dosing of the mineral constituents and plant preservation means as an answer to the changeable demands for them in various areas of the field. As for realization of the postulates of this system is concerned, more and more precise machinery is needed. Recently the most common machines used for distribution of mineral fertilizers are the centrifugal spreaders. The main criterion for their work quality is the transverse distribution pattern on the spreading width. Its profile depends on many factors. The laboratory measurements of their influence on the fertilizer distribution are being carried out in spreading halls that are specially built for this purpose, which makes them very expensive. It is the reason why for several years now an alternative method of researching the work of the spreaders is being developed. This method is based on computer simulation. An analysis of the literature from the area of the mathematical modeling of the fertilizer distribution process based on the movement of this particles on the spreader disc and in the air has been presented in the first part of this research. In the further part is presented own simulation program and compared with similar presented in the literature. The last part consist of own simulation measurements, which goal was to specify the influence some factors have on the transverse distribution pattern.
