Water Resources — Question 29

Advantages of Sprinkler Irrigation are:

1. This type of irrigation does not involve any wastage of water by seepage or evaporation as water is supplied through pipes and not exposed to the sun.
2. This is the best method for conservation of water.
3. It is best suited for arid and semi-arid regions.
4. Water management is easier than surface irrigation system.
5. Higher application efficiency.
6. Frequent application is possible.
7. Does not interfere with the cultivation.
8. Easy mechanization and automation.
9. Chemical and fertilizer application can easily be used with sprinkler system.

Disadvantages of Sprinkler Irrigation:

1. High initial cost.
2. High operating cost.
3. Water application efficiency under sprinkler irrigation is strongly affected by direction of the wind.
4. Some crops are sensitive and may suffer leaf scorch because of salt deposited on the leaves after the water evaporates.
5. High maintenance requirements as constant and meticulous maintenance of sprinkler system is very important.
6. Saline water may cause problems.
7. Water must be free from sand debris and salt.
