A 3 year study shows gains of +69€/HA thanks to fertilisation advice by drone on wheat

OCEALIA has been evaluating AIRINOV service over 3 years on 1734 wheat crops. The result : +69 €/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 stopped the development of the plant at key stages. Despite this complicated year, OCEALIA makes a positive economic assessment on 1734 crops of wheat at Z33 :  +17 €/ha of margin for the farmers who applied AIRINOV advice!

13 EXTRA KG OF N APPLIED WITH AIRINOV IN 2016

Standard dose: 40 kg N/ha  –  AIRINOV dose: 53 kg N/ha

+13 €/HA INVESTED IN NITROGEN

On average, AIRINOV adviced for OCEALIA’s 1734 wheat fields to apply 53 kg N/ha, i.e.  13 exta kg N/ha saved compared to the standard fertilisation amount of 40 kg N/ha.

+0,32 T OF YIELD INCREASE WITH AIRINOV IN 2016

Total of fields with yield maps: 484  – Average increase in yield: 0,32 T/ha

+40 €/HA OF MARGIN FOR THE FARMER

Farmers who applied less Nitrogen than AIRINOV advice missed an opportunity of  0,32 T in yield increase, value at 125 €/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.

MORE MARGIN FOR 3 YEARS

Variably apply Nitrogen on wheat with AIRINOV always improve margins, up to 103 € in 2015.

+205 €/HA OF MARGIN OVER THE 3 YEARS

+69 €/HA OF MARGIN ON AVERAGE PER YEAR

Managing Nitrogen on Wheat with AIRINOV always improves  margins, from 17 €/ha during the very difficult year of 2016 up to  103 €/ha in 2015. This difference mainly depends on weather  conditions.

THE WORST: +17 €/ha in 2016 –  THE BEST: +103 €/ha in 2015
