Irrigation : The process of supplying water to the crop plants is called irrigation.
Methods of Irrigation :
(i) Wells : These are of two types :
Dug wells : In dug wells, water is collected by bullock-operated devices or by pumps.
Tube wells : It makes very deep underground water available for irrigation. Motor pump is used to lift water.
(ii) Canals : These get water from large rivers.
(iii) River lift system : In this system, water is directly taken from rivers through pumps. This system is useful for irrigation in areas close to river.
(iv) Tanks : These are small storage reservoirs.
(v) Rain water harvesting : Rain water harvesting is a accumulation of water in tanks for later use. This also prevents soil erosion.
