How the modern methods of irrigation …

The modern methods of irrigation help us to use water economically. The two main modern methods of irrigation are:

1.  Sprinkler system – In sprinkler system of irrigation, a main pipe is laid in the fields to which perpendicular pipes are joined at regular intervals. When water from a tube-well is allowed to flow through the main pipeline under pressure with the help of a pump, it escapes from the rotating nozzles and gets sprinkled on the crops. This method of irrigation is more useful for the uneven land and sandy soil where sufficient water is not available. 
2. Drip system – In the drip system, there is a network of narrow pipes with small holes in the fields. When water falls through these narrow pipes, it falls drop by drop at the position of the roots of the plants. There is no run-off or wastage of water. This technique is the best technique for watering fruit plants, trees and gardens.
