Variable rate application (VRA) and Controlled traffic systems (CTF)has a wide ranging potential such as improving the utilization of crop nutrients, improvement of crop quality, reduced overlaps and better production economy. VRA focus on the site-specific application of fertilizers, pesticides and water whereas CTF can allow farmers to reduce input costs (time, inputs and fuel) and increase crop yields. Although both concept has the potential to improve the profit on many farms the adoption of PA technologies remains still low in Europe.
