evapotranszpiració

Evapotranspiració is the combined process of evaporation and plant transpiration. Evaporation is the process by which water is converted from a liquid to a gas or vapor. Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Together, these two processes account for a significant portion of water movement from the land surface to the atmosphere. This process is a critical component of the water cycle and plays a vital role in determining the amount of water available in an environment. Factors influencing evapotranspiration rates include temperature, humidity, wind speed, solar radiation, and the availability of water. In agriculture, understanding and estimating evapotranspiration is essential for efficient irrigation management, as it helps determine crop water requirements. Various methods exist to measure or estimate evapotranspiration, ranging from direct measurements using lysimeters to indirect estimations based on meteorological data. The rate at which water is lost from a vegetated surface through evapotranspiration is a key indicator of water stress in ecosystems and agricultural fields.
