Irrigation
Water is artificially delivered to the soil by a variety of tube, pump, and spraying systems. In regions with erratic rainfall, dry spells, or potential drought, irrigation is frequently employed. There are many different kinds of irrigation systems, where water is distributed evenly throughout the entire area.
Surface water from rivers, lakes, or reservoirs, groundwater from springs or wells, and even water from other sources like treated sewage or desalinated water can all be used for irrigation. Therefore, it is crucial for farmers to safeguard their agricultural water supply to reduce the risk of pollution.
