![]() ![]() This system is common in flat areas of the United States. Water is distributed by a system of sprinklers that move on wheeled towers in a circular pattern. Water is distributed by overhead high-pressure sprinklers or guns from a central location in the field or from sprinklers on moving platforms. In this type of irrigation, evaporation and runoff are minimized. Water is distributed under low pressure, through a piped network and applied to each plant.Ī type of localized irrigation in which drops of water are delivered at or near the root of plants. Water is distributed over and across land by gravity, no mechanical pump involved. Some common types of irrigation systems include: There are many different types of irrigation systems, depending on how the water is distributed throughout the field. As with any groundwater removal, users of irrigation water need to be careful in not pumping groundwater out of an aquifer faster than it is being recharged. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination. ![]() Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. There are many types of irrigation systems, in which water is supplied to the entire field uniformly. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. ![]() On the other hand, artificial applications of water increase the risk of contamination. Relying on rainfall is less likely to result in contamination of food products but is open to water shortages when rainfall is reduced. Rain-fed farming is the natural application of water to the soil through direct rainfall. There are two main ways that farmers and ranchers use agricultural water to cultivate crops: ![]()
