Question: What does a Lysimeter measure?
Options:
Evaporation
Evapotranspiration
Transpiration
Rainfall
-A lysimeter is an instrument used to measure evapotranspiration, which is the combined process of evaporation from the soil surface and transpiration by plants.
-It works by isolating a section of soil and vegetation, allowing precise measurement of water inputs (like rainfall or irrigation) and outputs (like water lost through evapotranspiration).
🛑 Additional Information::
-Evapotranspiration:Â It is the process by which water leaves the body of a living plant and reaches atmosphere as water vapour.
-A Lysimeter is a measuring device which can be used to measure the amount of actual evapotranspiration which is released by plants (usually crops or trees). By recording the amount of precipitation that an area receives and the amount lost through the soil, the amount of water lost to evapotranspiration can be calculated. Lysimeters are of two types: weighing and non-weighing.
