(N/A) Water logging and soil salinity are significant environmental issues resulting from intensive agricultural practices associated with the Green Revolution.
Causes:
- Irrigation without proper drainage systems leads to the accumulation of excess water in the soil,known as water logging.
- As water accumulates,it brings dissolved salts from deeper soil layers to the surface through capillary action.
Adverse Effects:
- Water logging creates anaerobic conditions in the soil,which hinders root respiration and stunts plant growth.
- As the water evaporates,the salts are left behind,forming a thin crust on the land surface or accumulating around the root zone.
- This increased soil salinity makes it difficult for plants to absorb water via osmosis,eventually leading to crop failure and land degradation.
