Advantages and Limitation of Sprinkler Irrigation
1. Suited to complete range of topographies and field dimensions.
2. High irrigation efficiency due to uniform distribution of water.
3. Accurate and easy measurement of water applied.
4. Land leveling is not essential.
5. Soluble fertilizer, herbicides and fungicides can be applied in the irrigation water economically and with little extra equipment.
6. More land is available for cropping.
7. No interfere with the movement of farm machinery.
8. Can be used to protect to crop against high temp that reduce the quantity and quantity of heaters.
9. Easy to operate, operator may be trained quickly.
10. Sprinklers are also used to irrigation high valued plantation crops like, coffee, cardamom and orchards.
1. It requires high initial investment.
2. Power requirement is usually high since sprinklers operate with more than 0.5 kg/cm2 water pressure.
3. Fine textured soils that have low infiltration rate can not be irrigated efficiently in host windy area.
4. Loss of water due to evaporation from the area during irrigation.
5. The water must be clean and free of sand, debris and large amounts of dissolve salts.
6. Wind distorts sprinkler pattern and cause uneven distribution of water.
7. Ripening of soft fruit must be protected from the spray.
