Question

State two dangers of overwatering.

Answer 1

Overwatering leads to serious problems of soil salinity and alkalinity.

1. 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.
2. Overwatering has brought about the devastation in large tracts of land. The sandy soils become alkaline and the loamy soils become saline-alkaline.
