What can be the effect of waterlogging?
1 Damaging the crops
2 Draws salt to the surface of the soil
3 Salt starts collecting at the roots of the plants
4 All of the above.
Explanation:
Besides affecting the crops, waterlogging draws salt to the surface of the soil. The salt then is deposited as a thin crust on the land surface or starts collecting at the roots of the plants. This increased salt cont ent is inimical to the growth of crops and is extremely damaging to agriculture.
