The invention concerns a process and/or device for determining control data for a fertilizer spreader. In order to determine these control data, a mini-laboratory or small appliance is provided which analyses the scattering properties of the fertilizer, the control data being deduced on the basis of these fertilizer-specific values. The following process steps are involved: a specific amount of fertilizer is placed in a calibrated measuring vessel (38) so that the apparent density can be determined from the amount and the volume resulting from the filling level; by opening a lower discharge aperture in the measuring vessel, the flow behaviour through a defined cross-section can be determined by measuring the discharge time; by introducing the fertilizer from the measuring vessel into a rotating device (34) formed as a centrifuge, the dwell time of a fertilizer granule and/or of a plurality of fertilizer granules and/or an introduced amount of fertilizer in the centrifuge can be determined, from which the friction rolling behaviour can be deduced. The energy content of a fertilizer granule and/or of a plurality of fertilizer granules can be determined by an arrangement of acceleration pick-ups (45) at the edge of the centrifuge (34). |
