Question

What are the three disadvantages of well irrigation?

Answer 1

Three main disadvantages of well irrigation are:

1. Limited Coverage and Capacity: Wells and tube wells have limited coverage and capacity compared to massive canal networks or large lakes, making them unsuitable for large-scale commercial farming.
2. Risk of Groundwater Depletion: Excessive groundwater extraction by continuous pumping may drastically lower the water table, causing wells to run dry and raising the expense of further drilling.
3. Dependence on Reliable Power Supply: Electric or diesel-powered tube wells largely depend on a steady source of electricity or fuel; frequent power outages or high fuel costs can seriously interrupt irrigation schedules and injure crops.
