Scientific Irrigation Scheduling

Scientific Irrigation Scheduling allows a grower to fine-tune irrigation by using soil moisture monitors, weather station data and evapotranspiration rates. Experienced vendors across the state offer the service and software that meet specifications for energy savings. In addition to water and energy savings of 10% or more, many growers also report reduced use of fertilizer, which has direct impacts to their bottom line and the environment.

  1. Contact Energy Trust to establish your eligibility.

    Call 503.928.3154 or email streamlinedindustrial@energytrust.org.  To be eligible for the incentive, you must sign up with Energy Trust before ordering or purchasing any related equipment or services and before the start of your irrigation season.
