Irrigation can affect the water balance of an area in many ways. For example, in some regions, it can affect environmental flows, groundwater stocks, and the amount of rainfall. In some regions, however, increased efficiency and fewer applications can improve water sustainability. Here are some examples of areas where wastewater irrigation can be used. Read on to find out how. Irrigation can be a useful tool for farmers. However, it is important to consider its costs before making a decision.

The transport system of irrigation is often determined by the type of water supply. For example, surface irrigation requires a large water transport system, while subsurface irrigation requires a smaller one. Surface irrigation is not suitable for highly sandy soils, as it can cause uncontrolled water distribution, floods, and soil erosion. This method only works in areas where water supplies are abundant. Localized irrigation, on the other hand, distributes water under low pressure through pipes or tubes to each plant.
In a localized irrigation system, the water source, filtration system, and pipes are connected to sprinkler heads. They then rotate in a circular, lateral, or rectangular pattern to distribute the water evenly to each plant. The irrigation system may be manually operated or a purpose-built mechanism. If there are a few sprinkler heads on a central pivot, the farmer can manually adjust the water pressure and distribute it to each section.
Agricultural lands with good irrigation systems can boost crop production without the need for rain. As an added bonus, irrigated land is ideal for exporting food. The crop productivity can be boosted by applying irrigation at any time of the year. For the sake of exporting food, the agricultural industry relies on irrigation. A well-irrigated field can produce more food than would otherwise be possible. In the midwestern United States, where rainfall is scarce, irrigation is essential for food production and increases rural income.
Another method of irrigation is subsurface textile irrigation. This type of irrigation works in all soil types and can even be used for fields with high water tables. A typical subsurface textile irrigation system consists of an impermeable base layer, a drip line, and a geotextile placed on top of the drip line. The geotextile moves water up to two meters above the dripper and maintains the soil’s water table. The water is also pumped back to the holding tank, which provides water for the plants.
Another irrigation resource that can be useful to farmers is the Irrigation Energy Self Assessment Tool. This tool can help farmers calculate how much irrigation energy they use, and how to decrease it. The USDA Natural Resources Conservation Service has developed this tool to calculate irrigation energy use and reduce it. The eXtension Agricultural Energy Community of Practice has published three video segments about irrigation energy. The first one features Dr. William Kranz on the topic.
