Sprinkler

Sprinkler irrigation system allows application of water under high pressure with the help of a pump. It releases water similar to rainfall through a small diameter nozzle placed in the pipes. Water is distributed through a system of pipes, sprayed into air and irrigates in most of the soil type due to wide range of discharge capacity. Advantages.

  • Eliminates water conveyance channels, thereby reducing conveyance loss.
  • Suitable in all types of soil except heavy clay.
  • Water saving up to 30% - 50 %.
  • Suitable for irrigation where the plant population per unit area is very high.
  • Helps to increase yield.
  • Reduces soil compaction.
  • Mobility of system helps system operation easy.
  • Suitable for undulating land.
  • Saves land as no bunds required.
  • Soluble fertilizers and chemicals use are possible.
  • Provides frost protection & helps in alteration of micro climate.
  • Reduces labour cost.

General Classification of Sprinkler Irrigation System Sprinkler systems are classified into two major types based on the arrangement of spraying irrigation water.

Portable system Rotating Boom type
Semi permanent system Permanent system

Types of Sprinklers Based on Precipitation
