Question

What is the typical range of pressure at which tensiometers are used in soil moisture measurement?

A 0.5 to 1.5 bar Correct Answer Incorrect Answer
B 0 to 0.8 bar Correct Answer Incorrect Answer
C 1.5 to 2.0 bar Correct Answer Incorrect Answer
D 2.0 to 2.5 bar Correct Answer Incorrect Answer

Solution

Tensiometers are commonly used in the negative pressure range (tension), typically from about 0  to 0.8 bar, to measure soil moisture and determine when irrigation is needed, as they reflect the soil's ability to hold water against the force of gravity.
