Question

Prolonged liberal irrigation of agricultural fields is likely to create a problem of

• A. Acidity
• B. Alkalinity
• C. Salinity
• D. Metal toxicity

Answer 1

The correct option is C Salinity

• Irrigation is the application of controlled amounts of water to plants at needed intervals.
  
• Prolonged liberal irrigation of agricultural fields is likely to create a problem of salinity, loss of nutrients from the soil. as more amount of water enters through the xylem vessels of the plants the soil becomes waterlogged, vegetations and crop die due to insufficient supply of oxygen.
• Hence Prolonged liberal irrigation of agricultural fields is likely to create a problem of salinity.
• So, the correct answer is 'Salinity'.
