Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of instruments used to measure soil properties.
Step 2: Detailed Explanation:
Keen's box is used to determine the water holding capacity (A) of soil.
It is a simple apparatus used to measure the amount of water retained by a soil sample after saturation and drainage.
Other options:
- Soil temperature (B): Measured by thermometers.
- Soil permeability (C): Measured by permeameters.
- Soil moisture tension (D): Measured by tensiometers.
Thus, Keen's box is used for water holding capacity.
Step 3: Final Answer:
Thus, Keen's box is used to determine water holding capacity, which corresponds to option (A).
