You can use sub-fields to measure out areas for different uses and to keep accurate records. This feature will let you record different crops, have multiple treatment areas and keep different livestock groups within one field.
Sub-fields don't change your field boundaries and apply for one year only. You can set usages, add notes, field jobs and attach livestock.

We will look to develop an archiving feature soon. If you have any feedback at all please contact firstname.lastname@example.org
Note: If you delete a sub-field then the jobs that were part of that field will become part of the activity list.
