Abstract

Objective. This article presents the results of research on the theoretical substantiation of the behavior of hairy seeds soaked in an aqueous solution of mineral fertilizers and micronutrient compositions after falling from the spreader. Methods. The essence of this technology is that the seeds are first sorted in an electric field on all their physical and mechanical properties.The sorted hairy seeds are delivered to the vertical cylinder at a certain rate and spread in conical spreaders, soaked in a mixture of water and mineral fertilizers, then collected in truncated cone-shaped collectors and dropped into a hemispherical shell drum rotating at a certain speed around a vertical axis. Results. Seeds moving in the aqueous solution of macro- and micronutrient compositions are affected by the driving force R x =km(V 0 ) of the flow along the X axis and the resistance force R z =km z along the Z axis and the gravitational force G = mg. Taking into account these forces, the motion of the hair seed in the aqueous solution of macro- and micronutrient compositions is calculated.
