A crop field (Jordbruksskift) is a contiguous area of land within a block where a farmer grows a crop or otherwise manages the land. To receive compensation for agricultural support (EU support), farmers apply for support from the Swedish Agency for Agriculture via a SAM application. The data set contains parcels where the area applied for and the area decided on are the same. The data is published at the end of a year.
