EXAMPLE OF RECOMMENDATION MAP ON AN HETEROGENEOUS OILSEED RAPE FIELD

Variably apply Nitrogen on heterogeneous oilseed rape enables to get more yield. 

An irregular development, some soil effects…

We can see here a very strong variation of biomass measured by AIRINOV, from 700g to 3,5 kg/m².
A farmer should adapt its fertilisation strategy when seeing such a difference in its parcel.

Standard dose: 160 kg N/ha – AIRINOV dose: 112 kg N/ha

Thanks to this measure of biomass, AIRINOV can assess the need for Nitrogen of the crop and make a recommendation map*.
The recommendation map is made in two versions:

  • in a simple zoning, which can be used to do manual variable rate application of N
  • in a complex zoning, which can be used to automatically variably apply the N

48 KG N/HA SAVED VS. STANDARD PLAN

100 kg N/ha  difference between the 2 zones in the manual VRA map

154 kg N/ha difference between the zones in the automatic VRA map

*the recommendation is adapted to the country’s agronomic conditions.
