When the VRA map is complete, the next step is to build control strips. Control strips are necessary to interpret the results of the trial, i.e., how planting, fertilization, or plant protection product application affected yield. The app builds control strips automatically, so you don't need to memorize the rules for how to do that. That said, you should still make sure you follow the platform's recommendations.

How to build control strips:

  1. Choose the number of control strips. There are two options:

    • 1 control strip with the normal rate in high- and low-productivity zones.

    • 2 control strips with the following rates in each zone:

      • Normal and low rate — in the high productivity zone.

      • Hight and low rate — in the medium productivity zone.

      • Medium and high rate — in the low productivity zone.

        Our recommendation is to use 2 strips in each zone because it's better when all productivity zones are covered with three rates.

  2. Specify the machinery's direction. This is the direction the machinery is operating in.

  3. The app will determine the width of the control strips. The range from 70 to 120 m allows you to visually determine how rates affect yield. The width will take the following rule into account: the whole control strip should lie within a homogenous area of a productivity zone.

  4. By default, control strips are built perpendicular to the machinery's direction. They can be built parallel to the machinery's passes only if it's not possible to build them perpendicularly.

  5. Now you just need to go to the 'Download' tab, select the file format, download it to your computer, and upload it to the machinery's onboard computer.


If control strips are built parallel to the machinery's passes and the field is harvested by several combine harvesters, it will be hard to interpret the trial results because of the difference in the harvesters' calibration. Please make sure that harvesters are properly calibrated before harvesting a field in which you set up a trial.

The adventure begins! Now it's time to go to the field and perform the operation! But to get insights into your field, you have to wait for harvesting to be done, so be patient!

By the way, the OneSoil modem can be of great help here. It can transfer files with the results of field operations between machinery's onboard computers and yours. Just click the button on the modem, and the files will appear on your computer. Upload them to OneSoil, and you'll see if the field has any gaps after performing a field operation.

Sounds interesting!
