- The process of supplying water to crop plants in fields through canals, wells, reservoirs, tube wells etc. is known as irrigation.
- Wells, tube wells, ponds, lakes, dams, rivers and canals are some of the sources of irrigation.
Need for irrigation:
- To make the soil soft due to which ploughing of fields can become easier
- To provide moisture for germination of seeds
- To maintain the moisture of soil for healthy crop growth
- For the absorption of nutrient elements by the plants from the soil
- To protect crop plants from hot air currents as well as frost
Harmful effects of excessive irrigation:
- Excess of water in soil leads to water logging
- Sometimes, it inhibits the process of germination
- Roots do not grow properly in a standing water field
- Excess irrigation destroys standing crops
- Increases the amount of salt on the surface soil as water evaporates
