EXPERIMENTAL INVESTIGATIONS ON THE SURFACE APPLICATION OF SUPERPHOSPHATE BY THE FERTILISER SPREADING TOOL WITH INCLINED AXIS

Abstract

One of the possible ways to significantly increase the spreading distance of fertilisers (and, accordingly, efficiency) by the fertiliser spreading tools may be creation of a structure with an inclined axis of rotation. For experimental investigations an experimental setup was developed and a solid mineral superphosphate granular fertiliser was used as a material. Increasing the angle of inclination of the disc of the fertiliser sowing tool with an inclined axis in a horizontal plane from 0 to 30º at a disc rotation frequency of 1000 min-1 leads to an increase in the effective sieving distance of granulated superphosphate by 34.9. It has been established that the best indices of mineral fertilisation both in terms of the operating width and the irregularity of the fertiliser introduction are provided at the angles of inclination of the disc of the new fertiliser distributing tool in a horizontal plane within 25-30º.
