State two reason why irrigation is important to a country like india ?
Answers
(1) About 80 per cent of the total annual rainfall of India occurs in four months, i.e. from mid-June to mid-October. So it is essential to provide irrigation for production of crops etc, during the rest of the eight months.
(2) The monsoons are uncertain. So irrigation is necessary to protect crops from drought as a result of uncertain rainfall.
(3) It does not rain equally in all parts of the country. So irrigation is necessary for agriculture in less rainfall areas.
(4) Soils of some areas are sandy and loamy and therefore porous for which a major portion of rainwater sinks down very quickly. So, sandy and loamy soils can't retain water like the alluvial soil and the black soil. That is why irrigation is essential for farming in the areas having, sandy and loamy soils.
(5) The rain-water flows down very quickly along the slopes of hillsides. So irrigation is necessaryto grow crops in such areas.
