Answers
Answer:
Drip Irrigation system is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 litres per hour) from a system of small diameter plastic pipes filled with outlets called emitters or drippers.
Water is applied close to the plants so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves wetting the whole soil profile.
With drip irrigation water, applications are more frequent than with other methods and this provides a very favourable high moisture level in the soil in which plants can flourish.
Explanation:
Advantages of Drip Irrigation

No over irrigation.
Variation in application rate.
Weed control.
Increase in net irrigable area.
Nutrients preservation.
Effective peat control.
Reduced labour cost.
No soil erosion.
Suitability for saline soils.
Maintenance of high surface temperature.
Suitable for any topography.
Disadvantages of Drip Irrigation
