This tutorial consists of four videos adding up to slightly more than one hour of instruction for growers and consultants. It introduces free weekly crop ET reports. They are heavily geared towards orchard crops and are available throughout the Central Valley of California.  Discussion includes who provides these weekly reports, why, and how to access the information. The videos explore the scientific basis for these weekly estimates of crop water use. This tutorial provides step-by-step instructions and examples of how to read the reports and apply the information to help make re-occurring decisions on when to irrigate and how long to operate specific irrigation systems. Finally, the videos demonstrate useful calculators to help water managers make various conversions and calculations.
