Question:
Water which is held at soil water potential greater than \(-15\) bars is called:
Water which is held at soil water potential greater than \(-15\) bars is called:
Show Hint
Water below \(-15\) bars is mostly unavailable; water above this limit is generally considered available.

- Available water
- Unavailable water
- Frozen water
- Superfluous water

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Permanent wilting point is generally taken at about \(-15\) bars. Below this level, plants cannot extract water effectively.
Step 1: Understand the given potential.
The question says: \[ \text{Soil water potential greater than } -15\ \text{bars} \]
Step 2: Compare with permanent wilting point.
Water above permanent wilting point is generally available to plants, especially when it lies between field capacity and wilting point.
Step 3: Final answer.
Therefore, water held at potential greater than \(-15\) bars is called: \[ \text{Available water} \] \[ \therefore \text{Correct Answer is (A)} \]
