Question

Soil salinity is measured by [BHU 1995]
A) Porometer
B) Potometer
C) Conductivity meter
D) Calorimeter

Answer 1

it is C conductive metre .....

Answer 2

Answer:  

The answer is option (C). 'Soil salinity' is measured by 'Conductivity meter'.

Explanation:

The porometer is a battery-operated device and it is used to measure stomatal conductance of leaves.  Potometer is also sometimes called as transpirometer. It is used to measure water uptake of a leafy plant shoot.

The conductivity meter is used to 'measure' the amount of electrical current or conductance in a solution.

The calorimeter is used to measure the heat of 'chemical reactions'.
