प्रश्न
Answer the following question.
State two dangers of overwatering.
उत्तर
Overwatering leads to serious problems of soil salinity and alkalinity.
- With the intensification of canal irrigation, the water table rises sufficiently and once the water table is within 2 meters, it is likely to act as a continuous source of soluble salts in the soil profile.
- Overwatering has brought about the devastation in large tracts of land. The sandy soils become alkaline and the loamy soils become saline-alkaline.
