Variable rate prescriptions – Fertilizer tool

Variable rate prescriptions – Fertilizer tool

Applying fertilizer is a common agricultural activity that can be completely automated with the correct implementation of variable rate application technology (VRT).

The biggest problems with variable rate applications are that farmers may not know how to create nutrient response zones on their farms or know how to assign rates to those zones. To solve these problems, Agremo developed a decision aid tool for creating variable rate prescriptions.

How does it work?

Users identify field variability – plant health (Nitrogen status analysis), create management zones (Fertilizer Tool), assign rates (Fertilizer Tools) and create Prescription files (Variable Rate Prescriptions). Based on this, users can optimize application operations by applying the right amount of nutrients on the right spots. 

Step 1

Go to the tools panel in result tab.

Step 2

Select the fertilizer tool.

Step 3

Enter all necessary information and click Apply button

  • Planned date of application
  • Pesticides type
  • Tile size
    • Users have ability to choose from three different tile size
      • 3×3 meter
      • 10×10 meter
      • 20×20 meter 
  • Number of zones 
    • The number of zones that the user selects determines the number of zone ranges. User can choose from two to six zones
  • Manually enter rates to each zone
  • Choose rate unit
    • Imperial units: 
      • US tons per acre (907.18474 kg)
      • Kilograms per acre
      • Grams per acre
      • Pounds per acre (0.45359237kg)
      • US Fluid per acre (0.0295735 liters)
      • Gallons per acre (3.785 liters)
    • Metric units: 
      • Metric tonnes per hectare (1000 kg)
      • Kilograms per hectare
      • Liters per hectare
      • Milliliters per hectare
  • Choose zone range
    • Zone range represents health percentage per zone. In this case we have five zones, the first zone range is 0-20 which represent stress levels between 100% and 80% of stress. If we change zone range to 0-25 it will represent stress levels between 100% and 75% of stress.
  • Click on Apply button

Step 5

Export Rx shape file and prescription PDF report will be generated and info message will appear.

Creating Variable Rate Prescriptions

An Rx or “Prescription” map is an electronic data file (shapefile ) containing specific information about input rates to be applied in every zone of a field.

What Our Clients Say About Us

  • After introducing mapping and crop analysis reports to farmers, they could see their field from another perspective. Agremo is helping us bring essential information to farmers which were impossible to get until recently.

    Ramón Pagán

    Mapping Expert and President @ Caribe Drones // Puerto Rico

  • Agremo’s map is more specific. Competitors break their maps into half-acre grids, but Agremo colors the whole thing exactly how it is. Visually, it’s night and day. A lot of farmers are visual.

    Corey Nohl

    Drone Operator and Farmer @ Above All Aerial // MN, USA

  • With Agremo reports, farmers they can increase productivity, reduce major problems by having early warnings during the early stages of the crops preventing major losses. Bottom line, increase ROI while minimizing losses.

    Miguel Ángel Salgado

    General Manager & Mapping Expert @ Ansar Drone // Mexico

  • The best thing about the plant population reports is the accuracy, which is splendid and it is very important! Great service at eye level with the customer!

    Sune Enevoldsen

    Field Manager and Drone Operator @ Noble Nordmann // Denmark

  • The biggest benefit for farmers who use drones and Agremo reports is that they increase their yields, reduce costs or improve their productivity. In the end, all these benefits are lead to extra profits.

    Ciprian Iorga

    General Manager @ La Orizont // Romania

  • We introduced new farming methods to farmers in Africa, who recognized that Agremo and drones can provide them with quicker, more convenient, efficient and accurate way of gathering decision making information.

    Derrick Annan

    CEO @ Aeroshutter // Ghana

  • With Agremo, we doubled our productivity, and our forestry clients are happy with the Agremo reports necessary for the inventory system as well as a stem map with tree distribution.

    Curt Rogers

    Co-owner @ TimberDrone // USA

  • Of the few vendors who advertised drone imagery analytics, Agremo provided a vastly superior capability. It is extremely important to base any remote sensing assessment in solid ground truth. Agremo clearly excelled over their competitors.

    Konrad Kern

    Image Scientist @ Falcon Aerial Data // USA

  • Agremo Stand Count Analysis shows how successful seeding was and how many plants farmers will be able to harvest. Withal, it can help to apply different sowing standards in different parts of the plot, in order to achieve the highest yields.

    Zdravko Hojka

    Agroservice and Product Manager (Maize and Oil Crops), KWS SAAT AG

  • Since we ran our first report with Agremo, both our company and our customers continue to be impressed with the accuracy of the reports compared to our ground truthing. We have leveraged many Agremo reports but find the most value in crop health, weed and stand count analyses. We continue to leverage the Agremo intelligence as a proven way to improve our customers’ bottom line.
