Dumb question for today:
At around 2 minutes, there are rectangular fields with green circles... why are the crops planted in circles instead of using the full field?

-John (who's only ever seen crops filling the field area)

US farmers were impressed by the UK "UFO Crop Circles" and, being
inventive types, figured out a way to make circles automatically thus
leaving them with time to go to tractor races.

Seriously, it's an irrigation system with a well at the center and a
rotating sprinkler pipe up to half a mile long. An irrigated circle
produces more crop than a square relying on rainfall. It's probably a
transient phenomena given the rate at which aquifers are being
depleted.
