Scientific Irrigation Scheduling (SIS) Calculator

Federal agencies seeking to help utilities assist their irrigation customers with scientific irrigation scheduling-related water and energy savings now have the power of our Scientific Irrigation Scheduling (SIS) calculator. SIS Calculator programs help irrigators apply the correct amount of water to their crops, based on crop type, growing season, soil types, and weather conditions. Our SIS calculator can provide general potential water and energy savings estimates resulting from implementing SIS on a given field or crop. SIS Calculator benefits include reductions in water use, irrigation water pumping energy costs, fertilizer use due to run off, and soil pollution, as well as the potential for improved crop quality.

The calculator is an easy-to-use Excel-based tool that illustrates SIS-generated savings based on:

• Crop and farm characteristics
• Irrigation system type
• Pump system(s)
• Simplified Engineering Assumptions

Using this information, the calculator creates water and energy savings estimates. These outputs can help utilities justify customer eligibility for financial incentives related to irrigation curtailment programs.
