## Question

Discuss the advantages and disadvantages of sprinkler and drip irrigation.

## Short answer

Sprinkler irrigation suits undulating land and light soils, saves water with 65-80% efficiency, but has high energy cost and wind distortion. Drip irrigation achieves 85-95% efficiency by wetting only the root zone, ideal for orchards and water-scarce areas, but suffers from emitter clogging and high initial investment.

## Answer

#### Sprinkler irrigation
Water is sprayed under pressure through nozzles, like rainfall.

**Advantages**
- Suitable for undulating and steep land; no land levelling is needed.
- Suitable for sandy and light soils with high infiltration.
- Saves water (efficiency 65-80%); application is uniform and controlled.
- No runoff or deep percolation if designed well; saves the land otherwise used for channels.
- Fertilizer and pesticide can be applied through the water; protects crops from frost and heat.
- Low labour.

**Disadvantages**
- High initial and energy costs (pump, pressure).
- Wind distorts the spray pattern, causing uneven application.
- Evaporation losses in hot, dry weather.
- Not suitable for heavy clay soils with low infiltration, or for rice.
- Wetting the leaves can spread disease and can scorch them if the water is saline.
- Needs skilled operation and clean water.

#### Drip (trickle) irrigation
Water is delivered drop by drop near the roots through tubes and emitters.

**Advantages**
- Highest efficiency (85-95%); uses the least water, so it suits water-scarce areas.
- Wets only the root zone, so there is less weed growth and less evaporation.
- Excellent for orchards, vegetables and sloping land; copes better with saline water.
- Fertigation is easy; high yield and quality; low labour.

**Disadvantages**
- High initial cost.
- Emitters clog (filters are needed).
- Not suitable for closely spaced field crops.
- Tubes may be damaged by rodents, sunlight and farm operations.
- Salt may collect at the edge of the wetted zone; root spread is limited.
- Needs training and maintenance.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Why is sprinkler irrigation useful on undulating land?
   A. No land levelling is needed
   B. It needs a perfectly flat field
   C. It works only on heavy clay
   D. It requires channels on every slope
   Answer: A. Water is sprayed under pressure so slope matters little. (Key point: Sprinkler land suitability)

2. What is a main disadvantage of sprinklers related to weather?
   A. Rain stops the nozzles
   B. Wind distorts the spray pattern and causes uneven application
   C. Frost is created by spraying
   D. Cloud reduces pressure
   Answer: B. Wind drifts the spray, and hot dry weather adds evaporation loss. (Key point: Wind effect)

3. Which has the highest efficiency and why?
   A. Sprinkler, 95%, because it wets the whole field
   B. Furrow, 90%, because of seepage
   C. Drip, 85-95%, because it wets only the root zone
   D. Wild flooding, 80%, because of gravity
   Answer: C. Drip applies water drop by drop near roots, minimising evaporation and loss. (Key point: Drip efficiency)

4. What is a key problem specific to drip systems?
   A. Wind distorts the pattern
   B. Leaf wetting spreads disease
   C. Heavy land levelling is required
   D. Emitters clog and need filters
   Answer: D. Small emitters block with silt or salts, so filtration and maintenance are needed. (Key point: Clogging)
