Question

Which among the following irrigation method is most sustainable?

• A.
  Sprinkler
• B.
  Drip
• C.
  Chain pump
• D.
  Moat

Answer 1

The correct option is B

Drip

• In drip irrigation system, each plant has a separate water source in the form of small pipe. Each small pipe is further connected to a large pipe which is in turn connected to a pump for a water supply.
• Once water is supplied to the pipe, it is released drop by drop into the soil near the plant roots.
• In contrast to other irrigation systems such as chain pump, moat system or overhead sprinklers, water can be precisely supplied to the plants in drip irrigation system.
• If designed, installed and managed properly, this method greatly contributes to water conservation by reducing evaporation.
