A method for determining calibration parameters of an agricultural spreader, comprising the steps of:Removal of material by means of the distributor in the case of predetermined parameters of the distributor,Determination of the second measurement parameters, by means of a second measuring system for the characterization of the distributing parameter is - of the distributor,Comparing the determined is - distributing parameter with desired, - and parameters,Repeating the steps a) - c) under adaptation of the setting parameters of the distributor to the distributing parameter is - with the distribution parameters - should correspond at least virtually,At least in the case of correspondence of the distributing parameter is - to - and the desired parameters: determining first measurement parameters, by means of a first measuring system and detection of at least one material specific calibration parameters for the first measuring system of a balancing of the first and second measurement parameters and / or from the first measurement parameters, taking into account of the set, - divided-up.
