Which of the following is not a traditional irrigation method?

Concept

Irrigation methods can be classified by the way they lift and deliver water to crops.

Traditional methods generally use simple human- or animal-powered lifting devices, whereas modern methods use controlled pipe-based delivery systems.

Application

The moat system uses a rope-and-pulley arrangement to lift water from a well, while the chain pump raises water with a moving chain of discs or buckets. Both are traditional water-lifting methods. A drip system carries water through pipes and emitters and releases it drop by drop near plant roots.

Contrast

• Moat system: a traditional method in which a rope-and-pulley arrangement lifts water from a well for field use.

• Chain pump system: a traditional lifting method that uses a moving chain fitted with discs or buckets.

• Drip system: a modern micro-irrigation method that delivers controlled drops near the root zone.

• More than one of the above: this would require at least two listed methods to be non-traditional, but the classification gives one.

• None of the above: this would require zero listed methods to be non-traditional, but the classification gives one.

Result

Therefore, the method that is not traditional is the drip system.
