How to Measure Evapotranspiration (ET)? | Agriculture

In this article we will discuss about how to measure evapotranspiration in crop plants. The concept of PET was given by Thornthwaite (1948) who defined it as evapo-transpiration from a large vegetation covered land surface with adequate moisture at all times. According to Dalton (1882), Evaporation is a function of the difference in the vapour pressure of the water and [...]

How to Measure Evapotranspiration ? | Plant-Water Relationships | Agronomy

Evapotranspiration is not easy to measure. Specific devices and accurate measurements of various physical parameters or the soil-water balance in lysimeters are required to determine evapotranspiration. The methods are often expensive, demanding in terms of accuracy of measurement and can only be fully exploited by well-trained research personnel. Although the methods are inappropriate for routine measurements, they remain important for [...]
