Advantages and Disadvantages of Well and Tube Well Irrigation
Advantages of Well and Tube Well Irrigation:
- Wells are the most basic and affordable source of irrigation, accessible even to the poorest farmers in India.
- Wells provide independent irrigation that can be used on demand.
- Well water often contains beneficial chemicals like nitrate, chloride, and sulphate, which enhance soil fertility when applied to agricultural fields.
- Well irrigation is more dependable during droughts when surface water sources are scarce.
Disadvantages of Well and Tube Well Irrigation:
- These methods can only irrigate a small area; typically, a well can irrigate between 1 to 8 hectares of land.
- Overuse of wells can lead to their depletion and ineffectiveness for irrigation.
- During droughts, groundwater levels decrease, reducing water availability in wells when needed most.
- Tube wells can deplete groundwater resources in surrounding areas, leaving the land dry and unsuitable for agriculture.
- Salty groundwater renders well and tube well irrigation impractical in certain regions.
