What is evapotranspiration?

Explanation:
Evapotranspiration is the total water vapor loss from a vineyard, coming from both the soil surface and the vine itself. Water evaporates from the soil around the roots, while the vine loses water through transpiration as leaves and other plant parts release vapor after taking up water. If you only consider transpiration, you miss the soil’s contribution; if you only consider soil evaporation, you miss what the plant loses. Water loss from grape skins isn’t treated as a separate ET pathway in standard practice. So the total ET is the combination of soil evaporation plus vine transpiration.
