Question

Continuously water-logged soils are disadvantageous for plant growth. Why?

Answer 1

Water-logged soil makes lesser oxygen available fo plants for respiration and affects their growth.

• The main function of roots include water absorption and uptake of oxygen from the pore space of the soil. ​

• In normal soil, oxygen from the pore spaces moves into the roots.​

• However, in waterlogged soil, water occupies the spaces between soil particles and pushes the oxygen out into the atmosphere. ​
  
  So, continuously water-logged soils are disadvantageous for plant growth.
