By measuring the reflectance of the canopy, N-Pilot® accurately determines the nutritional status of crops and directly advises on the amount of nitrogen to be applied. The N-Pilot® is a portable reflectometer measuring the nitrogen nutrition status of crops, plant chlorophyll content and the amount of biomass.

Easy measurements for immediate results

 Measurements with N-Pilot® are carried out in 20 seconds while moving through the field.

  • Ease of use facilitates the assessment of differing nitrogen nutrition across the field, calculating fertilization requirements accordingly.
  • Field diagnosis can include as many N-Pilot® measurements as necessary.

The device provides fertilization advice that takes the following parameters into account:

  • Crop variety
  • Expected yield
  • Growth stage of the crop
  • and protein target (grain protein content).
Key facts
  • The diagnosis is fast, reliable and cost effective.
  • It provides direct nitrogen fertilization advice in the field.
  • Controls and optimises both yield and protein content.
  • There are no subscription fees or any extra costs.
  • The N-Pilot® is a robust and autonomous device adapted to the terrain.
  • It can be used by multiple users.
  • Newly updated varieties and new species.
  • It has a wide spectrum of use: Soft wheat, hard wheat, wheat, winter barley, spring barley, triticale and rape.

For a good management of nitrogen fertilization

The following measurements and estimations optimize grain yield and protein content:

  1. Estimating the total nitrogen requirement of your crop.
  2. Splitting this total dose into several applications. 
  3. 3Using the N-Pilot® to adjust the dose of the latest nitrogen inputs for a better yield/protein compromise.

Crop Measurement periods (growth stages):

  • Soft wheat - 2 nodes and at ear emergence
  • Hard wheat - 2 nodes and at ear emergence
  • Spring wheat - 2 nodes and at ear emergence
  • Winter/spring barley - 1-2 nodes


The use of the N-pilot is based on a comparison between an over-fertilized zone (reference zone) and the rest of the field. The creation of a reference zone is therefore essential for the calibration and use of the N-Pilot.

The reference zone is part of the field to be checked. This calibration allows the tool to account for all other parameters such as variety, previous crop, type of soil, sowing condition, plant health protection, etc.). The only difference between the reference zone and the rest of the field lies in the nitrogen status. Nitrogen is not a limiting factor in the reference zone. Each measurement is expressed as a percentage of the index obtained on the reference zone. Advice to readjust the nitrogen dose is provided instantly.
