When to use sprinkler irrigation

Short answer

Sprinkler recommended for: undulating/steep land, sandy/shallow soils, water scarcity, close-growing crops, frost protection, and costly labour. Advantages: no levelling, high efficiency (65-80%), uniform application, fertigation possible. Disadvantages: high capital/energy cost, wind distorts uniformity, leaf wetting promotes disease, not for heavy clay or rice.

What are the situations in which you would recommend sprinkler irrigation? Discuss its advantages and disadvantages.

Situations for recommending sprinkler irrigation

  1. Undulating or steep land where levelling is costly.
  2. Light sandy soils with high infiltration, or very shallow soils.
  3. Water scarcity and a need for uniform, controlled application.
  4. Close-growing crops (cereals, pulses, fodder, vegetables, tea).
  5. Frost protection, cooling or germination of seeds.
  6. Where labour is costly or scarce and land is expensive (no channels).
  7. Where pressure from gravity or an electric/diesel pump is available.

Advantages

  • No land levelling; saves land used by channels.
  • High efficiency (65-80%); no runoff or deep percolation if designed well.
  • Even distribution; precise control of depth; can apply fertilizer and pesticides through it.
  • Protects against frost; low labour.

Disadvantages

  • High capital and energy cost.
  • Wind spoils uniformity; evaporation in hot weather.
  • Leaf wetting spreads disease and causes scorch with saline water.
  • Not suitable for heavy clay soils or rice.
  • Needs skilled operation, clean water and regular maintenance of nozzles.
