​The Benefits of Scientific Irrigation Scheduling

Scientific Irrigation Scheduling (SIS), also known as Irrigation Water Management, helps irrigators know exactly when and how much to irrigate crops through a system that monitors weather and soil moisture data. In many situations, SIS reduces energy costs for pumping water, conserves water, and reduces fertilizer use and runoff. In determining when to irrigate, the system takes into account the specific type of crop planted in a monitored field.

Benefits of SIS include:
• Saves water
• Reduces energy used for pumping and irrigation
• Reduces fertilizer requirements and leaching
• Improves crop yields and crop quality in many cases

​How SIS Works
SIS is a tool growers can use to improve irrigation water management. SIS uses information collected by installed soil moisture monitors and weather data collected via the internet. The collected soil and water measurements lets growers know when soil water levels are depleted, helps determine exactly when to water, how much water is needed to irrigate crops, and how to apply water to satisfy crop water requirements and avoid plant moisture stress.
​How BPA Supports SIS

BPA offers utilities reimbursements for SIS. This measure only applies to agricultural systems where pumping capacity is above that needed to meet the normal needs of the crops. Participants have the flexibility to determine the crops and fields to monitor or enroll. Based on a recent impact evaluation of this measure, BPA will no longer support SIS effective December 31, 2018.

Please note: BPA does not provide incentives directly to Agricultural Producers. Please contact your local utility for details.
