Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of methods for determining soil moisture constants.
Step 2: Detailed Explanation:
The pressure plate membrane apparatus is used in the laboratory to determine soil moisture constants (field capacity, wilting point).
Tensiometer (A): Field measurement of soil moisture tension.
Neutron probe (B): Field measurement of soil moisture content.
Gypsum block (C): Field measurement of soil moisture.
Thus, the pressure plate membrane apparatus is used in the laboratory.
Step 3: Final Answer:
Thus, the commonly used method for determining soil moisture constants is the pressure plate membrane apparatus, which corresponds to option (D).
