About this listen

Join us for a powerful conversation with Stuart Eyring, CEO of Orbit Irrigation, as we dig into one of the most important — and often misunderstood — concepts in irrigation: Evapotranspiration (ET). ET is the combination of water lost through soil evaporation and plant transpiration. It is the scientific foundation of modern irrigation scheduling, helping determine how much water is needed and when.


This session will provide a technical yet practical breakdown of how ET is calculated, the environmental variables that influence it, and how leveraging ET data can optimize water use for landscapes, sports fields, and crops.


In this live session, Stuart will:


  • Define ET and explain why it’s central to water conservation.
  • Break down the key factors used to calculate ET.
  • Show how understanding ET helps prevent over- or under-watering.
  • Share tips for using local weather and landscape cues to fine-tune irrigation.
  • Explore how ET applies across lawns, sports fields, and crops — and why it’s vital for each.


This is more than a science lesson — it’s a practical guide to using water wisely in 2025 and beyond. Whether you’re a landscape contractor, grower, parks manager, or water agency leader, this is one session you don’t want to miss.
