A method for electronic wind compensation of a fertilizer spreader, a control system designed for this purpose and a fertilizer spreader equipped therewith are described. Accordingly, the latter discharges fertilizer onto an agricultural area by means of rotating spreading discs, wherein the positions of feed surfaces for the fertilizer on the spreading discs are set in dependence on desired ejection angles which are individually adapted for the spreading discs in a compensatory manner on the basis of a wind prevailing during discharge, in order to counteract a deviation, caused by the wind, of an actual transverse distribution of the fertilizer from a desired transverse distribution. By virtue of the fact that the rotational speeds of the spreading discs are also adapted in a compensatory manner in order to counteract a deviation, caused by the wind, of an actual casting distance of the fertilizer from its desired casting distance, it is also possible to effectively compensate for undesired wind influence of headwind or trailing wind.
A method for electronic wind compensation of a fertilizer spreader which discharges fertilizer onto an agricultural area by rotating spreading discs, wherein the positions of feed surfaces for the fertilizer on the spreading discs are set as a function of desired ejection angles, which are compensatorily adapted for the spreading discs individually on the basis of a wind prevailing during discharge, in order to counteract a deviation of an actual transverse distribution of the fertilizer from a desired transverse distribution caused by the wind, wherein rotational speeds of the spreading discs are compensatorily adapted in order to counteract a deviation of an actual casting distance of the fertilizer from a desired casting distance caused by the wind, wherein a database and/or at least one function for characterizing a plurality of different discharge situations and/or wind conditions and/or spread patterns is provided and actual ejection angles and actual casting distances are calculated on the basis of the respectively set spread pattern and the measured/estimated wind.
