Question

A water-logged soil is physiologically dry because of

• A. Anaerobic conditions
• B. Non movement of water capillaries
• C. Increased viscosity of water
• D. Abundance of salts

Answer 1

Answer: (A)

Anaerobic conditions

Water-logging indicates to the concentration of soil with water. When the soil is saturated with water over the course of time leads to blockage of air passages and anaerobic condition is succeeded, now the soil may be regarded as waterlogged. In the intense condition (physiologically dry) continued waterlogging leads to anaerobiosis (life sustaining by organism in the absence of oxygen), mostly occurs to mesophytes roots, denitrification and methanogenesis due to reduced atmosphere.

So, the correct answer is option A.
