Answer 2

$\large{\sf{\underline{\underline\red{Answer!!}}}}$

• The supply of water to crops at different intervals is called Irrigation.

• Sources – Wells, Tube wells, Dams, Rivers etc.

Two methods of irrigation :-

• Sprinkler system – This system is more useful on uneven land where sufficient  water is not available. The perpendicular pipes having rotating nozzles on top are  joined to the main pipeline at regular intervals. Water flows from the main  pipeline under pressure with the help of a pump from the rotating nozzles and  sprinkled on the crop like rain. It is useful for sandy soil.

• Drip system- In this system, water falls drop by drop directly near the roots. It is  the best technique for watering plants, garden and trees. There is no wastage of  water at all.
