Evapotranspiration Calculator
The use of water by plants can be estimated by calculating what is known as potential evapotranspiration (pET). This is the possible loss of water through evaporation and transpiration. Transpiration is the movement of water through a plant from the soil into the roots, up the stem, and out through the leaves.
