What are the two reasons why well irrigation is popular in North India and which state of the country tube well is not used for irrigation?
North India has wide spread deposition of alluvial soil which is suitable for well irrigation. In south India ground water reserve is far below the surface but in north India the ground water level is within easy reach. The land is soft and fertile and thus wells can be easily dug at minimum cost whereas, there are rocks present everywhere in the Deccan region thus making it impossible for the wells to be dug. Wells can be dug easily wherever needed in the area to be irrigated while in southern India it is not possible. Wells are still popular means of irrigation due to the reasons: Firstly, surface wells can be constructed at a very low cost while construction of inundation canals from rivers is not within the reach of poor farmers. Secondly, wells can be used even during summers. Irrigation is important to a country like India because rainfall here is seasonal in nature. It is limited to four months of a year. It is also important because some crops require more water than what it is provided by the rainfall; therefore we have to depend on irrigation. Large dry tracts of Rajasthan, the adjoining parts of Punjab, Haryana, and Gujarat and some parts of Uttar Pradesh have brackish ground water which is not fit for irrigation and human consumption and hence unsuitable for well irrigation.
