| USGA Summary Points: | Two irrigation research trials were conducted in southern California to investigate the response of hybrid bermudagrass (Cynodon dactylon) and buffalograss (Buchloe dactyloides) to a wide range of ETo-based and soil moisture sensor (SMS)-based irrigation treatments. The smart SMS-based controller closely followed the programmed thresholds but the irrigation applications differed between years for the same treatments when converted to ETo percentages. The hybrid bermudagrass NDVI values decreased across the treatments from year one to year two, which is attributed to salinity build-up in the root zone due to the application of recycled water. The smart ET-based controller showed an acceptable performance (4 to 10% overirrigation) compared to CIMIS ETo values. Our findings indicate a significant increase in treated wastewater use between 2000 to 2015. Golf courses in Riverside, San Diego, Los Angeles, Orange, and San Bernardino, counties with the most golf courses, replaced surface potable water with treated wastewater, and in 2015 treated wastewater accounted for about 50% of all water use. Meter level analysis of water use by golf courses indicates that golf course potable water use is less than 0.5% of all potable water use in the sample water agencies. Our analysis indicates that water use was reduced by about 30% in 2017 compared to 2013 due to drought and demand management policies. This is comparable to the statewide mandate 25% reduction in urban water use. Our analysis indicates that, due to COVID-19, in April 2020, water use was reduced by approximately 80% compared to the same months in 2018 and 2019. However, in July 2020, water use started returning to the levels of 2018 and 2019 and was not statistically different from the 2018 and 2019 levels. |
