Variable Rate Application Soil herbicide

The minimum effective dose of soil herbicides depends, among other things, on the organic matter and clay content in the soil. The higher these values, the higher the minimum effective dose. Soil maps can be ordered from service companies that scan and map your field with EC, NIR or Gamma radiation sensors. You can also make a soil map based on own insight in the variation of the soil properties, e.g. via the Farmmaps Zoning app, and then use this map in the Soil Herbicide app.

The decision rules (dosing algorithms) that are applied in the Soil Herbicide app are derived from pot experiments, extended where appropriate with expert judgement. For more information about the basic model and the specifications, reference is made to the PPL report 80 at https://www.precisielandbouw-openteelten.nl/dossiers/112-vra-gbm-bodemherbiciden-en-granulaten.

Choose in a few steps in the app:

1. The soil map you want to use
2. The agent you want to use is allowed in the crop
3. The sprayer you want to work with and settings

As you go through the steps, you will be presented with an application map showing the variation in minimum effective dose rates within the field. This map is then converted into a task map that represents the site-specific spray volume. This task map can be downloaded as a shape file or in ISO-XML format, and this task map file is then loaded in the terminal that controls the sprayer.
