Description |
Astronaut photo of the w:Al Khufrah Oasis in Libya. The circular objects are agricultural fields. The shape is characteristic of w:center pivot irrigation. These fields are approximately 0.6 mile (1 kilometer) in diameter. Darker colors indicate fields where such crops as wheat and alfalfa are grown. Lighter colors can indicate a variety of agricultural processes: fields that have been harvested recently; fields that are lying fallow; fields that have just been planted; or fields that have been taken out of production.
