Question:
Lysimeter is used for the measurement of
Lysimeter is used for the measurement of
Show Hint
Lysimeter weight changes directly reflect the combined water losses from transpiration and evaporation.
Updated On: Aug 24, 2026
- Density of soil
- Atmospheric pressure
- Relative humidity
- Evapotranspiration
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
A lysimeter is a scientific instrument designed to measure the water balance of a soil-vegetation system.
Step 2: Detailed Explanation:
Let us review the standard instruments for each parameter:
- Density of soil is determined using a soil core sampler or pycnometer.
- Atmospheric pressure is measured using a barometer.
- Relative humidity is measured using a psychrometer or hygrometer.
- Evapotranspiration is measured using a lysimeter, which registers water lost through soil evaporation and plant transpiration.
Thus, a lysimeter is used to measure evapotranspiration.
Step 3: Final Answer
The correct option is (D).
