Question

What is the electrical conductivity of saline soil?

• A. 2 ds/m
• B. 3.5 ds/m
• C. $>$ 4 ds/m
• D. 4 ds/m

Hint:

Saline soils have high electrical conductivity due to dissolved salts, which can affect plant growth by limiting the availability of water.

Answer 1

The Correct Option is C

The electrical conductivity of saline soil is typically greater than 4 ds/m. Soils with electrical conductivity higher than this are considered saline. Salinity in soil is caused by the presence of soluble salts, which affect the soil's structure and fertility.
