From this webpage:

"Now when you fly over the area in parts of Nebraska and Kansas, you may be surprised to see a very large number of green circles on the ground. These circles, most of which are a half-mile in diameter, are irrigated with central pivot sprinkler irrigation systems. You will see many of these circles if you travel on I-70 through eastern Colorado."

An aerial photo here.

Apparently, they have the same system in South Africa.

There are circular crop fields. The geometry is because the irrigation system (center pivot water jet).

Hope helps.
