Merits of Well and Tube Well Irrigation

♤ Well is simplest and cheapest source of irrigation and the poor Indian farmer can easily afford it.

♤ Well is an independent source of irrigation and can be used as and when the necessity arises. Canal irrigation, on the other hand, is controlled by other agencies and cannot be used at will.

♤ Excessive irrigation by canal leads to the problem of reh which is not the case with well irrigation.

♤ There is a limit to the extent of canal irrigation beyond the tail end of the canal while a well can be dug at any convenient place.

♤ Several chemicals such as nitrate, chloride, sulphate, etc. are generally found mixed in well water. They add to the fertility of soil when they reach the agricultural field along with well water.

♤ The farmer has to pay regularly for canal irrigation which is not the case with well irrigation.

♤ More reliable during periods of drought when surface water dries up.
