How do I Create a Custom Layer?
Check Strips or Test Blocks are regions of a field that are created by users for the purpose of testing any variable, such as seeding rate, treatment, or environmental factors. They are used to set up a treatment analysis, or adjust a variable rate prescription from VRS or Nitrogen.
