It's the way they water their fields, not what the fields grow.

This is produced by the way the fields are watered. A line carries water to the center, from which a very long plastic tube extends. The tube has many small holes on one side from which water is ejected, and the force of the water makes the tube move. The effect is to have it pivot around the center. From the air you see a circle of green. This was introduced in the 1970s as an efficient means of watering, although it does leave gaps.
