Study finds perennial biofuel crops’ water consumption similar to corn

Green Car Congress

Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground. This knowledge gap exists for perennial vegetation in general in mesic environments, and has important implications for how landscape water balances will respond to climate change.
