Technical Abstract: Precision irrigation is gaining attention by the agricultural industry as a means to optimize water inputs, reduce environmental degradation from runoff or deep percolation and maintain crop yields. This presenation will discuss the mechanical and software framework of the irrigation scheduling supervisory control and data acqusition system developed by USDA-ARS scientists at Bushland, Texas. The presentation will also provide insights as to how the system can be used by farmers to access variable crop water needs and apply appropriate amounts of irrigation using speed or zone variable rate control. A discussion of recent yield and water use efficiency results for corn grown in Bushland, Texas will also be presented.
