As a result of the performed analytical and experimental work, a studded belt mineral fertilizer feeder has been developed and manufactured. It can ensure applying a greater fertilizer portion on a wide area. Due to avoidance of batch feeding, it ensures uniform fertilizer distribution in the soil. Uniform fertilizer distribution on the belt conveyor, as well as in the soil, depends on the stud arrangement pattern on the belt surface. The article provides a rationale for the optimal parameters of the stud arrangement on the running belt, its optimum angle in the longitudinal vertical plane, and the longitudinal stud arrangement parameters. We have also developed the fertilizer feeder's structural design and provided a rationale for it, theoretically determined the main functional dependencies between its parameters. We have tested the capability of the experimental fertilizer feeder of mineral fertilizer feeding at an increased rate and determined its main parameters in laboratory conditions. Laboratory experiments confirmed the development prospects and a distribution irregularity reduction to 5.7%–8.4%.
