Question about Agriculture

Hello guys, I've been playing this game for a few days now and I'm already loving it.
I learned almost all the skills related to Agriculture (I can plant every crop) but now I have a question: should I have a field for every crop or like 9-10 fields with every bar filled to 100? How does it work exactly?
Thanks for your patience
