Vineyard Technology: Evapotranspiration

Jeff Lyon, a Lake County vineyard owner, explains that “evapotranspiration” was originally measured by placing a large pan of water in a field and then every day measuring the evaporation from the pan. He says that in the modern viticultural era evapotranspiration, or ET, is calculated based on measurable data such as relative, wind, temperature, and solar radiation. Bruce Merrilees then demonstrates a tool for measuring ET in the field. Once growers know the ET, they can replace a percentage of that water through irrigation, typically 25% to 30%.
