ABSTRACT PRIMARY purpose of this paper is the introduction of a new concept in irrigation system design along with a report of preliminary results. The system is characterized by and has been labeled a low energy-precision application (LEPA) system, which rather than spraying water into the air at moderate to high pressures, distributes it directly to the furrow at very low pressure through drop tubes and orifice controlled emitters. This occurs as the system continuously moves through the field in a linear fashion. The system is used in conjunc-tion with micro-basin land preparation which also op-timizes the utilization of rainfall by minimizing runoff, The combined system was designed to minimize the ef-fect of soil and climatic variables which adversely in-fluence furrow and sprinkler irrigation efficiencies. Significant savings of both water and energy resources are indicated from results of the testing to date.
