They are characterised by three indicators: terminal velocity, drag coefficient and fineness ratio. The aim of the study was to present a method and a research station for measurement of the aerodynamic properties of crop seeds in vertical and horizontal planes. The method assumes measurement of geometric properties of seeds by neuron image analysis and aerodynamic measurements in a specially designed station.
