| The term Evapotranspiration (ET) combines the concepts of evaporation (E) from soil and plant surfaces with transpiration (T) from plant leaves to describe the total water escaping from a crop to the air. Evapotranspiration increases with: higher air temperature, more solar (light) energy, lower humidity, and faster wind speed. Evapotranspiration is often referred to as "crop water use" because the two processes are so closely entwined and difficult to separate.
