Match List-I with List-II
Match List-I with List-II
Show Hint
- Tensiometer \(\rightarrow\) Soil moisture suction/tension (D-II).
- Penetrometer \(\rightarrow\) Soil strength/compaction (B-IV).
- FDR \(\rightarrow\) Soil moisture (E-III).
Linking these three properties quickly directs you to the correct option (D).

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Soil physics utilizes specialized instruments and physical concepts to quantify soil water potential, compaction, chemical forces, and moisture content.
Step 3: Detailed Explanation:
- Piezometer (A): A tube used to measure the hydrostatic pressure or hydraulic head (V) of groundwater at a specific depth.
- Penetrometer (B): An instrument pressed into the soil to measure resistance to penetration, which quantifies soil compaction or soil strength (IV).
- London-van der Waals forces (C): Intermolecular forces that affect the dispersion and flocculation behavior, dictating the pattern of molecular structure (I) in clays.
- Tensiometer (D): An instrument containing a porous cup used to directly measure the matric potential or soil moisture suction (II).
- FDR - Frequency Domain Reflectometry (E): An electromagnetic sensor used to measure the dielectric constant of soil, which correlates with soil moisture (III).
Step 4: Final Answer:
The matching sequence is A-V, B-IV, C-I, D-II, E-III. This corresponds to option (D).
