New Irrigation System Design for Maximizing Irrigation Efficiency and Increasing Rainfall Utilization

摘要

A new concept in irrigation system design, which has the potential of significant savings in both water and energy requirements, has been developed and is under evaluation. 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.
