transpiration

"We could exactly pinpoint how this is related to water transpiration and the ions the plant carries via the ascent of sap."

ET includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves.

Scientists have a variety of methods to estimate the amount of water ascending from the Earth's surface to the atmosphere due to evaporation and transpiration through plant leaves.

So, she compared transpiration in fallowed fields to active fields across the Central Valley.

Ultimately, a full 10% of crop transpiration could be saved if the top 50% of water users reduced their water consumption to match that of their median-consuming neighbors.
