Based on the analysis of fertilizer consumption rates for potato cultivation, a new design of a dosing coil-type device has been proposed for conditionally discrete application of granular mineral fertilizers into potato nests. The structural and kinematic parameters of this device have been substantiated. Using the developed theoretical models, the limiting values of the rotation frequency were determined based on the condition of groove filling with fertilizers. The law of particle motion in the fertilizer tube was established, which made it possible to determine the time it takes for a particle to fall to the bottom of the furrow. This, in turn, allowed for determining the lead angle of the fertilizer discharge phase relative to the phase of potato tuber release by the planting mechanism. The obtained parameter values made it possible to synchronize these two devices and increase the efficiency of the potato planting technological process.
