Nov. 2-6, 2003. Denver, Colo. Technical Abstract: Efficient use of limited water supplies in dryland cropping systems in the semi-arid Great Plains of North America is critical to system success. Water use efficiency increases with residue management practices that increase precipitation storage efficiency, soil surface alterations that reduce runoff, cropping sequences that minimize fallow periods, and use of appropriate management practices for the selected crop. Changes in system water use efficiency as cropping intensity increases from wheat-fallow to continuous cropping are noted from studies conducted in the northern, central, and southern Great Plains.
