Main Stream Precision Farming - 7.000 VRA Maps for Winter Rapeseed
R. Hoerfarter
SEGES

SEGES is owned by the Danish farmers and is an agricultural advisory centre advising landowners with a total of 2.1 mill hectare. One of SEGES’s goals is to make precision farming mainstream. One step in the process of making precision farming mainstream was in 2016 to give all farmers access to the free internet application CropSAT.dk. Here farmers can make variable rate application (VRA) maps based on satellite data from Sentinel-2. But this is not enough to make precision farming mainstream because a barrier for the farmer was to type in the amount of nitrogen in five levels, so a nitrogen model for winter rape was implemented in CropSAT. Still, only farmers interested in precision farming were reached and the goal was all farmers. Then the idea of pushing out all VRA maps for winter rape came up. To do this you have to have a site on the internet used by all farmers. SEGES has a platform like this where 2,000 unique users visit every day. Now, the farmer is showed all his winter rape fields with variable rate nitrogen.  In 2017 SEGES pushed out 7,000 VRA winter rape maps. In 2018 SEGES has pushed out 12,000 VRA maps on winter rape and 70,000 on winter wheat fields.
