Flood Irrigation
Flood irrigation (pronunciation: /flʌd ˌɪrɪˈɡeɪʃən/) is a method of irrigation where water is poured over the land surface and allowed to flow over the field. The term originates from the English words "flood" and "irrigation".
Etymology
The term "flood irrigation" is derived from the English word "flood", which means to overflow, and "irrigation", which refers to the artificial application of water to land to assist in the production of crops.
Description
In flood irrigation, water is distributed over the soil surface by gravity. It is one of the oldest methods of irrigation and is suitable for flat lands with high water tables. The water is allowed to cover the soil surface and soak into the ground. The water is then absorbed by the plants' roots.
Advantages and Disadvantages
Flood irrigation has several advantages. It is a simple and cheap method of irrigation. It does not require any special equipment or technology. However, it also has several disadvantages. It can lead to water wastage and soil erosion. It can also cause waterlogging, which can damage crops.
