Agricultural patterns from space – in pictures:
Resembling a work of modern art, variegated green crop circles cover what was once shortgrass prairie in south-western Kansas. The most common crops in this region are corn, wheat, and sorghum. Each of these crops is at a different point of development, accounting for the varying shades of green and yellow.
