Natural irrigation refers to the process of watering crops and plants using natural sources of water, such as rivers, lakes, and rainfall. This method relies on the natural flow of water to nourish the soil, promoting healthy plant growth without the need for artificial systems like pumps or sprinklers. Farmers often utilize techniques like flood irrigation or drainage ditches to direct water from these natural sources to their fields. By harnessing the power of nature, natural irrigation can be a sustainable and cost-effective way to maintain agricultural productivity, especially in regions with abundant water resources.
