Earth Day 2012 - Crop Circles Tote Bag

Sand Designs 'Out of this World' Special Edition to celebrate EARTH DAY 42nd Anniversary of Earth Day April 22, 2012. Crop Circles in Kansas - Resembling a work of modern art, variegated green crop circles cover what was once shortgrass prairie in southwestern Kansas. The most common crops in this region—Finney County—are corn, wheat, and sorghum. One conservation measure is using water more wisely so less is drawn out of the aquifer. Farmers in this region have adopted a more efficient irrigation method, central pivot irrigation. Central pivot irrigation draws water out of a single well in the centre of the field. Long pipes perched on wheels rotate around the pivot, showering the crops with water. Because the water falls directly on the crops instead of being shot into the air as occurs with traditional sprinklers, less water is lost to evaporation and more goes to nourishing the growing plants. Central pivot irrigation also creates perfectly circular fields, as seen in this image. The fields shown here are 800 and 1,600 metres (0.5 and 1 mile) in diameter.
