Flood irrigation is a method of watering crops by allowing water to flow over the soil surface. This technique involves creating channels or furrows to direct water from a source, such as a river or reservoir, to the fields. The water saturates the soil, providing moisture to the plants. This irrigation method is often used in agriculture for growing crops like rice and cotton. While flood irrigation can be effective in certain regions, it may lead to water wastage and soil erosion if not managed properly. Efficient use of this technique is essential for sustainable farming practices.
