Posted on March 12, 2020 by Anne Jefferson

Weighing lysimeters are one of the very best ways of measuring the actual evapotranspiration from a small area of land, because they use mass balance (i.e., changing weight) to give us the combined total of plant transpiration, soil evaporation, and interception losses over time.
