A 3 year study shows gains of +107€/HA thanks to fertilisation advice by drone on OSR

OCEALIA has been evaluating AIRINOV service over 3 years on 627 oilseed rape (OSR) crops. The result : + 107 €/ha of margin for the farmer!

Context

OCEALIA group is a 900 employees cooperative which can boast a member base of 7,200 farmers. Partner of AIRINOV since the start, OCEALIA has been evaluating the service over 3 years on oilseed rape (OSR).
In France, AIRINOV measures OSR biomass at the beginning and end of winter. Those measures are approved by the reference institute on OSR crop, Terres Inovia. Thanks to those biomass measures, AIRINOV can assess the real need for Nitrogen of the crop and prepare a variable rate application map at a sqm precision. Detecting the zones in the field and measuring precisely crop development enables to apply the right dose at the right place and the right moment. Thanks to AIRINOV maps, a farmer can make more money by saving fertilizer and improving its yields.

During 2015-16 winter, the cold weather in France pushed the plant to develop. The gains made by re-assessing the need for N with AIRINOV method were very important: +171 €/ha of additional margin for the 627 fields on which AIRINOV advice was applied!

OCEALIA’s farmers & variable rate equipment

34 KG OF N SAVED WITH AIRINOV IN 2016

Standard dose: 197 kg N/ha  –  AIRINOV dose: 163 kg N/ha

+34 €/HA OF MARGIN FOR THE FARMER

On average, AIRINOV adviced for OCEALIA’s 627 OSR fields to apply 163 kg N/ha at the end of winter (split in 2 applications), i.e.  34 kg N/ha saved compared to the Standard fertilisation plan.

+0,5 T/HA OF YIELD INCREASE WITH AIRINOV IN 2016

Total of fields with yield maps: 204  – Average increase in yield: 0,49 T/ha

+152 €/HA OF MARGIN FOR THE FARMER

Farmers who applied less Nitrogen than AIRINOV advice missed an opportunity of  0,5 T in yield increase, value at 310 €/T in 2016. For those who applied more than the advice, the explanation lies in the small number of fields included in this sample, in the fact that extra crop growth isn’t productive for yield and in not doing modulation.

LARGE SAVINGS EVERY YEAR SINCE 3 YEARS

* OCEALIA uses the French method requiring 2 flights – other assessment methods exist and require only 1 flight.

+320 €/HA OF MARGIN OVER THE 3 YEARS

+107 €/HA OF MARGIN ON AVERAGE PER YEAR

Managing Nitrogen on OSR with AIRINOV always improves  margins, from 40 €/ha to 170 €/ha, depending on weather conditions.

THE WORST: +44 €/ha in 2015 –  THE BEST: +171 €/ha in 2016
