Some Significant Info About The Different Irrigation Systems
Indeed, the world is said to be getting thirstier. A lot of recent studies predicted that the water demand for plenty of countries will exceed the supply by 40% in 2030. The good news though is that for countries that can efficiently manage their water supply, they would most likely to be in the best position to nourish their economic prosperity.
With that said, plenty of countries are looking for ways on how they can conserve water, most especially in agriculture. Most nations are looking into what could be the best irrigation method to use in order to equalize supply and demand of water.
Drip – This is a planned irrigation system wherein water is applied directly to the roots of the plants through the use of applicators like porous tubing, perforated pipes, and emitters. It is actually operated under low pressure with the applicators placed on or below the ground surface.
Flood – This is the term used when the entire surface of the ground is covered by water.
Rotation – This is an irrigation system by which the irrigators receive a certain amount of water at stated intervals.
Subirrigation – This is done by applying irrigation water below the surface of the ground by raising the water table within or near the root zone. Apart from that, it can also be done by using a buried perforated or porous pipe systems which discharges directly to the root zone.
Surface – This is the irrigation method where the soil surface serves as the conduit, as in furrow and border irrigation as compared to subirrigation.
Sprinkler – Similar to the drip irrigation method, this is also a planned irrigation system. The water is applied through the use of perforated pipes or nozzles that are operated under pressure in order to form a spray pattern.
Traveling Gun – This is a sprinkler irrigation system that consists of one large rotating nozzle. This is self-propelled.
Furrow – This is a partial surface flooding method of irrigation that is commonly used with clean-tilled crops wherein the water is applied in rows of sufficient capacity in order to contain the designed irrigation system
Center-Pivot – This is an automated sprinkler irrigation which is achieved by automatically rotating the sprinkler pipe that supplies water to the sprinkler heads. The water is being delivered to the center of the system. The pipe is actually supported above the crop by towers placed with fixed spacing and propelled by mechanical, hydraulic, or electric power on wheels in a fixed circular path at similar angular speeds. The depth of water applied is being determined by the rate of travel of the system.
