If you are talking about the Reno area, and if we are thinking of the same large, green circles, they are grass.
From what I have figured out, they are large sod (as in the grass you transplant into your yard) plantations. The only reason I can figure out for them being circles is that it is easier to water circles. Sprinklers naturally shoot out water in circles. Anyway, that is always what I have thought.

The circles are are crop circles formed by center pivot irrigation systems. In the western United States, crop circles are most commonly 1/4 mile (400 meters) in radius so that four crop circles fit on a 640 acre (1 square mile = 2.59 square kilometer) section of land.

My first answer was center pivot irrigation systems, but they also "mine" salts in the salt flats of CA, NV & UT, sometimes using circular ponds.
