Techniques of irrigation and soil conservations and soil health cards Techniques of irrigation Surface Irrigation In this method water flows and spreads over the surface of the land. Varied quantities of water are allowed on the fields at different times. Hence, flow of water under surface irrigation comes under unsteady flow. As a … Read more
Major Irrigation Projects of India and Command Area Development Command area development programme The Centrally sponsored Command Area Development (CAD) Programme was launched in 1974-75 with the main objectives of improving the utilization of created irrigation potential and optimizing agriculture production and productivity from irrigated agriculture through a multi-disciplinary team under an Area … Read more
It involves applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. The pump supply system, sprinklers and operating conditions must be … Read more
It is a kind of irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of the plants, either onto the soil surface or directly onto the root zones, through a network of valves, pipes , emitters etc. It is done through narrow tubes that deliver water directly to … Read more
Different types of irrigation and irrigation systems There are two main ways that farmers and ranchers use agricultural water to cultivate crops: Rain fed farming irrigation Rain-fed farming Irrigation Rain-fed farming is the natural application of water to the soil through direct rainfall. Relying on rainfall is less likely to result in contamination … Read more
Irrigation and Water Resources Development provides the basic infrastructure for the growth of economy of the country and large investment has been made for the purpose in our country. Irrigation is an artificial application of water to the soil for crop production by constructing headworks (weir) across a river in case of flow irrigation … Read more

Merits: Most of the canals provide perennial irrigation. This saves the crops from drought conditions and helps in increasing the farm production. Canals carry a lot of sediments brought down by the rivers. The sediments is deposited in the agriculture fields which adds to the fertility. Some of the canals are parts of multipurpose project … Read more
Industrial Uses The share of industrial sector is limited to 2 per cent of the surface water utilisation and 5 per cent of the ground-water. Rough estimates indicate that the present water use in the industrial sector is of the order of 15 km3 . The water use by thermal and nuclear power … Read more
Surface Irrigation In this method water flows and spreads over the surface of the land. Varied quantities of water are allowed on the fields at different times. Hence, flow of water under surface irrigation comes under unsteady flow. As a result it is very difficult to understand the hydraulics of surface irrigation. However, suitable and … Read more
