Mobile Drip Irrigation (MDI)

Mobile drip irrigation (MDI) combines the high efficiency of surface drip irrigation with the flexibility, lower hardware costs, and convenience of center pivot irrigation. In this system, the drip tubing is attached to center pivot irrigation systems to apply water directly to the soil surface as the driplines are dragged across the field and to create a uniform wetting pattern across the entire irrigated area.

Low energy precision application (LEPA) and low elevation spray application (LESA) trials in the Pacific Northwest

LEPA and LESA are alterations on a center pivot where the sprinklers are moved much closer to the ground, the spacing between sprinklers is reduced (more sprinklers), and water is emitted at very low pressures. It saves water (18%), it saves energy (less water pumped and pumped at a lower pressure), and it helps growers get better yields especially in areas where water is limiting. However, it has an increased propensity for runoff, and the sprinklers operating below the top of the canopy can require some management changes. In many cases energy savings alone can pay for the increased costs of the additional sprinklers and drop hose. However, the largest profit potential lies in the ability to get improved yields in areas that are water short or have large water losses to wind drift and evaporation.
