This feature is available to "Professional" users.
You can use this tool to build cropping plans and immediately see your area precentages. You can also save, or load cropping plans to file. Your plans do not currently integrate into creating a new year.
Use the "Action" button menu to create a new field, or copy an existing field. To create split fields you will need to create, or copy a field and alter the areas to suit your new field layout.
As with all display grids in Field Track that can be edited, the updates only take place after you have clicked the mouse outside the grid being edited, or you move to another record.
The Crop Planner uses the IACS switch for each field to calculate the different figures for the graph based on 'Cropped', or 'IACS'.
