Recently, centrifugal fertilizer spreaders of various manufacturers are widely used for spreading granular organic fertilizers on the soil surface. In the technical literature or instructions are a lack of recommendations from the manufacturers of fertilizer spreaders how to set the parameters for granulated manure to achieve the required amount of fertilizer dispersion (spread) and the required uniformity of spread. This article analyses the uniformity of spreading organic granulated manure compost fertilizers in soil by a centrifugal double disc fertilizer spreader. Two types of manure pellets of different geometric characteristics were investigated for real outdoor spreading experiments, and blades of different lengths were chosen. From the analysis of the presented research results, it was determined that the centrifugal fertilizer spreader can be used to disperse (spread) granular cylindrical organic fertilizers. Also, from the obtained results a significant difference was found of spread between the used different diameters and length granules. In this article, it can be said that beside the mentioned and investigated fertilizer spreader parameters for spreading uniformity improvement it needs to take into account unexpected factors of the environment, like the wind direction and strength, pellet size, pellet size distribution, angle of spreading blade, etc.
