Raps, koolzaad, rapeseed

That's the sequence of the terms that come to my mind when I see a field like this one. Lucky me it's only three languages :).
I rode my bike a medium tour of 60km, and sometimes the smell of rapeseed was sooo good. Unfortunately the sun already hid behind the clouds, preparing for the three days of rain the weather forecast promised. But even without sun the fields were bright yellow, lovely.
