Applications of nitrogen, manure, and irrigation may be applied to parts or all of a VRT Grid field, and either at a constant or a variable rate. To remove an existing VRT Grid field's applications:
- Return to (or reload) the Field Configuration interface
- Open the layer of application type you wish to modify (e.g. Nitrogen Applications)
- Then click the "View Past Applications" link
- You will then be presented with a list of existing applications, with an option to Remove them
