The article describes the method of numerical modeling of the process of sowing seed material of small seed crops in the software package STAR-CCM + on the basis of the created 3D-model of the sowing machine and the adopted physical models. Boundary and initial conditions of modeling are presented. To check the created simulation of the developed sowing device of a selection seeder the visualization of process of its work is received and dynamics of quantitative expenses of seeds is defined. The calculation of the average value of the quantitative consumption of seeds and its standard deviation. It is substantiated that for further researches the following are chosen as research factors: execution of the expression of the dispenser of cylindrical form (І - triangle, ІІ - semicircle, ІІІ - rectangle), angle of rotation of the damper α, time interval when the damper is open or closed Δt, seed drill speed V.
