National audience; Nowadays, centrifugal spreading is the most used method to apply fertiliser in fields. Numeroustechnical developments have improved spreaders to reach high precision applications.Nevertheless, these developments have never taken into account the influence of the spreadingvelocity variation on the shape of the spread pattern. However, practical examples show that speedvariations regularly happen in the field. For instance, high speeds applications require punctualslowing down because of:- Trees or posts;- Slopes, hills;- Field borders/ends.Technical devices already exist to avoid the influence of the travel speed on the disc rotation speedand on the application rate in fie…
