Building a fertilizer plan

The fertilizer section stores your application schedule and ties every application to the field's operations log. And the AI dose suggestion isn't an empty number — it rests on the NDVI trend, crop norms and (if you've uploaded one) a lab analysis.

Where: Field → Work → “Fertilizer”

  1. Open the fertilizer section

    Open the field and go from the “Work” group to “Fertilizer”.

  2. Record the current schedule

    Add the fertilizers you're planning: type (nitrogen, phosphorus, potassium…), date and dose. The schedule shows across the season.

    Screen: “Fertilizer: Nitrogen,” “Date,” “Dose (kg/ha)” rows and “Add.”

  3. Get the AI dose suggestion

    The “Dose suggestion” button gives an approximate dose range taking into account the NDVI trend, crop norms and soil values. It's advice — the final decision is yours.

    Screen: a “Suggested dose: 60–80 kg/ha nitrogen” card and an explanation.

  4. Record the application

    When you apply the fertilizer, record it. The application goes into the operations log and into the next AI analysis.

Tips

  • If you upload a soil analysis, the dose suggestion rests on your measured values and becomes more accurate.
  • If you don't record the application, the AI doesn't know what the field received this season — and the suggestion stays generic.
  • The NDRE/CIre index shows nitrogen status more sensitively than NDVI.
