This is Field Status, version 15.1, for FS15. It’s a Lua script that will display the status of all fields on your map.
It will show what percentage of each field is plowed, cultivated, seeded, and/or fertilized. For each crop planted, it will display the percentage of the field covered, and the crop’s growth state, cut/windrow, and withering. Bales that are on fields will also be shown.
Also displayed are the map name, number of fields, and the hectares and acres for each field, along with the total for the map.
