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.
