Question

Continuously water logged soils are advantageous for plant growth.Why?

Answer 1

because the plants can grow easily and faster in these soils

Answer 2

Roots, although underground, possess living cells that require oxygen for respiration and production of energy. They absorb oxygen that is present in the spaces between soil particles. But in water-logged soils, water occupies the spaces between soil particles and pushes the oxygen out into the atmosphere. Thus, roots are deprived of oxygen and this affects root and plant growth.
