Operator is John Walton, University of Tennessee extension specialist. “Do More With Less: Feeding the World One Kernel at a Time“ Innovative technology and automation makes it possible for agriculturists to get more crop to the table quicker, as shown in this shot taken on the plains of western Kansas harvesting hard red water wheat. Photographer: Tom Trout Agricultural Engineer, Research Leader, USDA-ARS Water Management Research Unit, Fort Collins, Colorado, USA Photographer: Freddie Lamm Research Agricultural Engineer, Kansas State University Northwest Research-Extension Center, Colby, Kansas, USA “Taking the Heat“ Due to low moisture and high elevation, the U.S. High Plains commonly experiences wide ranges and extremes in temperature. The draught-tolerant sunflower is an excellent crop option for this area. “Driptape Job“ With the installation of subsurface driptape, the water is precisely placed in the soil root zone and uniformly distributed across the field to help maximize its productivity. Surface evapo-ration losses are minimized since the crop and soil surface are not wetted. Although the initial cost of drip systems is high, the resulting water conservation, high yields, and long life can combine to make drip systems a good economic choice.
