A great advantage of basin irrigation is that water is not wasted. Basin irrigation is a method of irrigation where a field is surrounded by earthen banks and divided into small basins. The basin is filled with water, and the water is allowed to infiltrate the soil to a certain depth.
In basin irrigation, the amount of water applied is just enough to fill the basin, and it stays there until the plants absorb it or it evaporates. This ensures that the water is not wasted by flowing away or evaporating before it can be used by the crops.
Another advantage of basin irrigation is that it is a simple and low-cost method of irrigation. It is suitable for small fields and can be easily constructed by farmers themselves. Basin irrigation also helps to reduce soil erosion and nutrient loss, and the basins can trap much alluvium to enrich the soil.
In summary, the great advantage of basin irrigation is that water is not wasted, as the water stays in the basin until it is absorbed by the plants or evaporates. Additionally, basin irrigation is a simple, low-cost method that can help to reduce soil erosion and enrich the soil.
