Scientific Irrigation Scheduling

 The Benefits of Scientific Irrigation Scheduling (SIS)

Scientific Irrigation Scheduling (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 addition to reducing energy costs for pumping water, SIS 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. Annual energy and water savings is estimated at 10 percent.

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 BPA Supports SIS

BPA offers utilities reimbursements for Scientific Irrigation Scheduling (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.

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

 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 the grower know when soil water levels are depleted, helps them determine exactly when to water, and how much water is needed to irrigate their crops, and how to apply water to satisfy crop water requirements and avoid plant moisture stress.
