Question

what is irrigation in long answer​

Answer 1

Answer:

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.

Answer 2

Irrigation

Irrigation essentially means the watering of land to make it ready for agricultural purposes. An irrigation system is the supplying of water via artificial canals and channels to growing plants and crops in a field.

Water is vital for the growth of plants. There can be no plants or crops if they do not have access to water in some form. It is, therefore, crucial to supply water to crops and plants, periodically and as per their requirement. So irrigation is this periodic and appropriate supply of water to plants. The water for this irrigation comes from various sources such as wells, ponds, rivers, dams, reservoirs, rainfall etc.
