what is irrigation why is irrigation necessary
Answers
Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection,[1] suppressing weed growth in grain fields[2] and preventing soil consolidation.[3] In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming.
Irrigation systems are also used for cooling livestock, dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the removal of surface and sub-surface water from a given area.
The process of supplying water to crop plants through different intervals is known as irrigation.
Irrigation is necessary because:-
1. It is necessary to provide moisture for the germination of seeds.
2. Irrigation before ploughing the fields make the soil soft due to which the ploughing of fields become easier.
3. It is necessary to maintain the moisture of soil for healthy crop growth so as to get good yield.
