Irrigation brings water to land through artificial means for crops, grass, and vegetation. Water sources include lakes, reservoirs, rivers, and wells. Methods include surface, sprinkler, drip, and subirrigation. Irrigation is also used for lawns, with some areas imposing water conservation measures.
Irrigation is the process by which water is brought to land through artificial means, such as pipes, tubes or ditches. The land that is irrigated usually contains crops, grass or vegetation that usually do not get enough water from rainfall or other natural sources. Sometimes the reason for irrigating a patch of land is that it happens to be in a dry season, with lower than average amounts of rainfall, or it may need to be done because that land would never get enough water on its own to be fertile. Water used for irrigation may come from nearby lakes, reservoirs, rivers or wells.
Use of water
The amount of water that needs to be used for irrigation depends on the type of crop being grown and the amount of rainfall in the region. There are some countries where water is used for irrigation of land more than it is used for other purposes. In the United States, about one-third of the water used each year is used for irrigation. Worldwide, it is more than half.
Water sources
Water that is brought to a farm from a surface water source, such as a lake or reservoir, usually comes through a series of channels. When the source is groundwater from a well, the water is pumped to the surface and transported to the farm through a network of pipes. In both cases, there are several ways that water can be lost in the soil irrigation process, including evaporation, runoff, and transpiration, which is the loss of water that has been absorbed by plants and plants. nearby weeds. There may also be algae blooms in surface waters, which could make the water unsuitable for irrigation.
Methods
There are many methods that can be used for farmland irrigation and each one needs an experienced farmer to know exactly how much water to use and when to use it. One such method is called surface irrigation, where the farmer disperses the water onto the land by flooding it or running it down furrows, which are lanes in the field. Another method is sprinkler irrigation, where water runs through pipes over or onto the ground and is then sprinkled onto the field. The drip or drip method uses an underground system of pipes to directly water plants and is one of the most water-efficient methods. Subirrigation uses an airtight layer of rock or soil that lies beneath the farm and water is distributed evenly over this layer so that it can be absorbed by crop roots.
Watering lawns
One of the most common uses for irrigation is for watering lawns. This is often done by a lawn sprinkler, which can come in many varieties. Some are installed underground and are connected to automatic timers so that they start watering your lawn at specific, pre-programmed times. Underground sprinklers are commonly found on golf courses, where the quality of the grass is essential to the business. Sometimes, during a particularly dry season, a city or region might impose a ban on the amount of water used to irrigate lawns, in order to conserve water supplies.
