Hi Kitsee, 

The fields may appear to have crops in them but on aerial imagery there are many hay meadows with hay bales that look like farmland.
Perhaps landuse=meadow would be a better tag, as the majority of fields within way 131600335 are hay meadows and pasture. I did not create way 131600335, it is really much too big for a landuse area and should be split into individual fields for accuracy.
