Limitations and responsibility
Farmers draw fields in Internet Markkort and report crops and areas through the annual agricultural declaration (Fællesskema). The information supports agricultural subsidy administration and checks. Applicants must also declare agricultural land for which they are not requesting support. The year is the application year. Winter crops are normally sown the previous autumn and harvested in the application year. Actual sowing and harvest dates are not reported.
