Overview

The Fertilizer Tool allows you to optimize nutrient application by creating Variable-Rate Fertilizer Maps based on crop conditions.

This tool is available based on the following analyses:

• AI Analyses – available for Plant Vigor

• Real-time Plant Health Analyses – based on all Vegetation Indices

• Satellite Imagery Analyses – based on all Vegetation Indices

How to Access

From AI Analyses

1. Open the uploaded Drone map for the selected field.
2. Go to the analysis results for Plant Vigor Analysis.
3. Click on the Tools tab.
4. Select the Fertilizer tool.
5. Select a predefined grid or create a new one by clicking the “Create Map” button.
6. The Fertilizer Tool will appear on the right sidebar

From Real-time Plant Health or Satellites

1. Open the uploaded Drone map or Satellite map for the selected field.
2. Click on the Tools tab.
3. Select the Fertilizer tool.
4. Select a predefined grid or create a new one by clicking the “Create Map” button.
5. The Fertilizer Tool will appear on the right sidebar

How It Works

1. Open the Fertilizer Tool – Access the Fertilizer Tool from your analysis to start creating a Precision spraying map.
2. Select your drone type or Tractor 
3. Select or Create a Grid – Choose a predefined grid based on tile size, or create a new one by clicking “Create Map.”
   • The tile size should match the working width of your drone or sprayer for optimal application.
4. Generate Prescription Map – Once you select the appropriate grid, your prescription map is automatically generated, showing field zones for Variable-rate application.

💡 Note: XAG and EAvision drones support only a 5×5 tile size for prescription maps.

4. Adjust Application Settings – Once the prescription map is created, customize your spraying parameters:

• • Apply an Operation Plan (including obstacles and no-spray zones) or create a new one
  • Set the number of zones for the application
  • Choose the rate unit (liters/kilograms or gallons/pounds, based on your system settings)
  • Define the application rate per zone (including herbicide and water)
  • Add a planned spraying date (optional)
  • Enter a treatment name (optional)

5. View Required Input & Estimated Savings – After setting all parameters, the platform automatically calculates the total input required and estimates your potential savings compared to uniform (flat) field spraying.

• If an Operation Plan is applied, obstacle and no-spray zones are excluded from savings and treatment calculations to ensure more accurate spraying estimates.

💡 Note: Since most drones support only the metric system (liters and kilograms), any values entered in imperial units will also be automatically converted to metric for use in controllers.

6. Modify Prescription Map

• • Use the slider below the histogram to quickly adjust zones and update your prescription map in real time.
  • For more precise control, you can also click “Modify Prescription map” to open the editing tool and fine-tune your map in detail.

7. Export Prescription map – Click “Export Tool Results” to open the export modal. Select your preferred option: drone (DJI, XAG, TopXgun, EAvision), tractor, or direct export to JDOC (John Deere Operations Center).

• • All exported files are ready-to-use and require no additional modification. Simply upload them to your drone, controller, or tractor system and start precision spraying immediately.
  • If an Operation Plan is included in the creation of a Prescription Map, it will be exported together with the Prescription Map

💡 Note: For JDOC export, make sure your account is connected within the Agremo app.
