Question

All given factors promote absorption of water by roots, except-

• A. Well aerated soil
• B. Highly concentrated soil solution
• C. Optimum soil temperature
• D. Available water in soil

Answer 1

The correct option is B Highly concentrated soil solution

A well aerated soil sufficient in oxygen increases water absorption by roots.
Highly concentrated soil solution results in high osmotic pressure which will result in lower absorption water by roots.
Optimum soil temperature will promote absorption as decreasing or increasing temperature may affect the state of water or transpiration or may cause cold injury to cells.
Water availability in the soil will make water readily available for roots to absorb.

So, the correct answer is 'Highly concentrated soil solution'.
