Question

Which of the following statement(s) is/are true for tensiometer?
(A) It measures soil water potential.
(B) It is simple in operation and very useful for scheduling irrigation.
(C) It can also be used for measuring soil water flux.
(D) Although limited to &lt: 1 bar matric potential, this range can be increased by increasing the permeability of its porous cup.

• A. (A), (B) and (C) only.
• B. (A), (B) and (D) only.
• C. A) and (D) only.
• D. (D) only.

Hint:

Tensiometers are best for monitoring water availability in the field, especially in the range close to field capacity.

Answer 1

The Correct Option is A

Tensiometers are used to measure soil water potential (A) and are commonly used for irrigation scheduling (B). While limited to $<$ 1 bar, improvements in porous cup design can extend their use (D). They are not suitable for directly measuring water flux (C).
