Data Sheet


Increase the profitability of your corn fields

FieldApex is a precise, trusted and simple solution for managing the application of fertilizer. It maximizes the profitability of your farm by calculating the optimal nitrogen rate to apply to your fields at the very moment of application.


A simple way to maximise your profit: optimizing your nitrogen rate

FieldApex answers the question of how much nitrogen to apply to your fields by balancing the need for successful crops with the cost of nitrogen. It calculates the rate that maximizes your profit — in other words, the “Economically Optimal Nitrogen Rate”, or EONR.

*Fixed rate maintained year over year regardless of the weather and/or non-split application of nitrogen.


A rate rimply made smarter

The artificial intelligence algorithm determines the most cost-effective rate in a matter of seconds.

Parameters taken into account in real time:

  • Past and future seasonal weather
  • Soil texture
  • Seasonal crop vigour, using satellite imagery
  • Grain and nitrogen prices
  • Previous crop grown
  • Organic matter
  • Average historical yields


Variation in the total nitrogen rate applied with FieldApex (lbs/acre)*

Depending on weather and soil texture

45 lbs/acre with the starter and the rest in post-emergence

* Scenario: Organic matter: 4.0%, probable yield (historical): 180 bushels/acre, nitrogen price/ton (N 100%): $1200, price per bushel of corn: $5,08, previous crop: wheat.

With FieldApex, you can better adjust your buffer for seasonal weather, and hence maximize your profit

Scientifically proven average savings

The key to maximized profit is to use FieldApex every year. The more extreme the weather, the more profitable. Normal weather will generate calculations closer to your usual rates.

Chose the AONR

* The average Agronomic Optimum Nitrogen Rate (AONR) is higher than the Economically Optimum Nitrogen Rate (EONR). It aims to reach your average maximum yield based on historical yields. Although less profitable than the EONR, the AONR focuses on securing yields while minimizing excess nitrogen application.
