The public funded research and development project "Pesticide Application Manager" (PAM), demonstrated during Agritechnica 2015 within the framework of Connected Crop Protection, is the first comprehensive solution to consider existing fix spray drift regularities in Germany with machine integration. It has been established an infrastructure to create boundaries of protected areas and the incorporation of official regularities available as buffer zones dependent on the crop protection, the crop, the protected area, the drift reduction technology, and the region. During spraying application the buffer zones are considered in respective to the used drift reduction technology. Beyond this approach significant improvements might be possible taking additionally weather data, sprayer settings e.g. boom height, application technique, and application amount into consideration. Individual legislation from several countries allows to use different modelling of buffer zones today (e.g. Sweden), but still the execution is on the operators responsibility and the buffer zones need to be permanently recalculated based on aforementioned changing conditions. This research study describes an approach to support spray drift models beyond the current official buffer zone calculation and regulatory. This includes the definition and accuracy of needed sensor information, sprayer model changes, new nozzle technologies as well as the on-the-go consideration and execution of buffer zones based on actual conditions into the application technique. Furthermore, a part of the study gives attention to valid documentation of the operation to prove the compliance conformity. This paper outlines the above-described approach in more detail and will provide a more profound insight into the nature of the results and ways they can be used.
