Abstract: In the semi-arid Pacific Northwest of USA, where less than 20 centimeters (8 in) of total annual precipitation occurs, exists the worlds largest contiguous drip irrigated farm of 10 360 hectares (25 600 acres), managed by Greenwood Resources Inc. and known as the Boardman Tree Farm (BTF). On this farm, 10 000 000 fast-growing Pacific Albus (Hybrid Poplar) trees are irrigated by a massive and complex automated water distribution system. Irrigation pumping energy is a major crop production cost, so a very aggressive and determined effort is made to operate the irrigation system efficiently and cost effectively. Some of the practices are the use of innovative design for closed-loop drip irrigation system, Advanced Scientific Irrigation Management (ASIM), automated soil moisture sensing and the use of one of the most advanced and sophisticated Irrigation Supervisory Control and Data Acquisition (I-SCADA) systems in the world. Additionally the use of an original and innovative methodology incorporating a customized Advance Hydraulic Balanced Irrigation Scheduling (AHBIS) computer program, for smooth and steady multiple pump stations hydraulic operation.
