Question:
Tensiometers measure the:
Tensiometers measure the:
Show Hint
Tensiometer measures soil water suction or matric potential.
Updated On: May 18, 2026
- Matric potential of soil moisture
- Electrical conductivity
- pH of the soil moisture
- Nutrient management in soil
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
A tensiometer is an instrument used to measure soil water tension or suction.
Step 1: Understand soil water tension.
Soil water tension shows how strongly water is held by soil particles.
Step 2: Relation with matric potential.
The force due to soil matrix attraction is called matric potential. \[ \text{Tensiometer} \rightarrow \text{Matric potential} \]
Step 3: Eliminate other options.
Electrical conductivity is measured by EC meter.
Soil pH is measured by pH meter.
Nutrient management is not measured by tensiometer. \[ \therefore \text{Correct Answer is (A)} \]
