what is needed for evapotranspiration
Evapotranspiration is abbreviated ET and is often called crop water use. The term evapotranspiration combines evaporation from soil surfaces with transpiration from plants to describe the total amount of water lost from a crop. Water evaporates from any moist surface into the air as long as the air is not saturated.This process is called evaporation.Evaporation from plants is called transpiration. Plant leaves evaporate water through tiny adjustable openings called stomates that are scattered across leaf surfaces. Water moves from the soil into plant roots, through the plant, and finally out through leaf stomates.vaporation from plants is called transpiration.
