Question

What is water logging?

Answer 1

Hint: Water logging refers to the accumulation of excess water in the roots of the plants which ultimately lead to the damage and deaths of the plants. Accumulation of water can also cause water lodging which also leads to death of the plants as the plant falls down due to heavy rain and water accumulation.

Complete answer:
Irrigation without proper drainage of water leads to water logging in the soil. It not only results in affecting crops and damaging them but also draws salt to the surface of the soil. The salt drawn to the surface is deposited as a thin crust on the land surface or starts collecting at the root of the plants. This ultimately increases the salt content which is inimical to the growth of crips and is extremely damaging to agriculture. Water looking leading to soil salinity are some of the problems that have come in the wake of the green revolution.
Both water logging and water lodging are the results of improper resource utilization practices.
The development of fertile topsoil takes centuries. It can be removed very easily due to human activity like poor irrigation practices, over-cultivation, unrestricted grazing, deforestation, etc. The removal of top fertile soil is known as soil erosion. Soil erosion leads to the formation of arid patches which extend and meet over time and leads to desert formation.

Note:
In water logging due to excess accumulation of water and salt in roots, the soil cannot absorb the water, which results in cutting down the oxygen supply to the roots and submerged plants of the plant. Due to this cut down of oxygen and nutrients supply the plants ultimately die. Because there are some elements which are essential for the proper growth and metabolism of the plants.
