What is Irrigation?
Irrigation is the replacement or supplementation of rain with another source of water. The most plan behind irrigation systems is that your lawns and plants are maintained with the minimum quantity of water needed Water is a fragile resource and that we got to incorporate ways to conserve it and not over-use it. The implementation of an irrigation system will help conserve water, while saving you time, money, preventing weed growth and increasing the growth rate of your lawns, plants, crops, and flowers.
Irrigation is the technique during which a controlled quantity of water is provided to plants at regular intervals for agriculture.
In straightforward words, it will provide water to plants to help them grow once there is not enough rain.
There are 2 main forms of irrigation systems: low flow and high flow. Each may be utilized in one garden if required. Low flow systems refer to small spray, drip emitters, or drip lines. High flow systems are fixed spray, rotor, impact, bubbler, and soaker hose. Drip irrigation is most well-liked for several elements of the garden except lawns. Wherever applicable, a sprinkler is also used for lawns or low-growing groundcovers. don’t forget that irrigation system should be designed to stop the wasting of water, low head emptying, overspray, or different similar conditions wherever irrigation flows onto non-targeted areas, like adjacent property, non-irrigated areas, landscapes, roadways, or structures.

types of irrigation:
Low flow irrigation (also referred to as small irrigation) refers to emitters, drip lines, small sprays, and mini rotors this is the foremost water-conscious of irrigation systems. The water is distributed directly onto the basic system of the plant. Drip irrigation must be run for a half-hour for it to require result. Pipes with perforated holes are buried slightly below the surface; a blocker only lets the droplets obtaining out one at the time.
Water will drop right where the root zone of a plant in a dripping motion. If the system is put in properly you’ll steady cut back the loss of water through evaporation and runoff.
Drip lines are a versatile tube with emitters (tiny water-flow regulators in every hole within the line) equally spaced on the tube. Drip lines are referred to as inline drip or subsurface drip. Some drip lines are also placed on top of the ground with AN emitter(s) at every plant and covered by a number of inches of mulch.
A subsurface drip line (underground) may be wont to irrigate ground covers. The installation will occur before (in the ground) or after (above ground) for ground covers. Water is applied very slowly in gallons per hour Inline drip should clearly operate at a reduced pressure so as to deliver solely a tiny low quantity of water at a specified rate; therefore needs a pressure reducer and filters, Drip systems may be connected to a hose finish and operated by hand, or for good connected to your main water supply and operated by an automatic controller.
This is Associate in nursing irrigation system based on overhead sprinklers, sprays or guns, put in on permanent risers. You’ll be able to also have the system buried underground and therefore the sprinklers rise when water pressure rises, that is a well-liked irrigation system to be used on golf courses and parks.
The pipes with a group quantity of water to the fields and then sprays it directly over the crops with high-pressure sprinklers. The profit is that the amounts of water will be controlled.
Head-to-head coverage is recommended; but, sprinkler spacing should be designed to attain the best potential distribution uniformity using the manufacturer’s recommendations. to stop overspray and runoff, overhead irrigation isn’t applicable among twenty-four inches (two feet) of any non-permeable surface. Sprinkler heads with check valves or anti-drain valves are extremely suggested to avoid water waste.
Ditch Irrigation is a rather traditional technique, wherever ditches area unit digs out and seedlings area unit planted in rows The plantings area unit watered by putting canals or furrows in between the rows of the plants. Siphon tubes are used to move the water from the most ditches to the canals. This technique of irrigation was once very fashionable within the USA, however, most are replaced with trendy systems.
Green wall irrigation
Green walls also use a type of drip irrigation for watering. Gradient plays an important role within the means the green wall irrigation controller is set. If set incorrectly it could cause flooding at the lower half of the green wall and dry conditions at the top.
This is a really labor-intensive technique of irrigation wherever the land is cut into steps and supported by retaining walls. The flat areas are used for planting and the idea is that the water flows down each step, while watering each plot.
Are more commonly used in flower beds. The nozzles are interchangeable to control volume, angle, and direction of water flow. A riser pipe needs to be on for 10 to 15 minutes to be effective for flowers. A riser pipe needs to be set at the correct time to ensure less evaporation and maximum absorption by the garden. If set in midday the dew drops on the plants can act as a magnifying glass and burn the leaves.
Rotary Systems/mist pipes
This technique of irrigation is best suited to larger areas, for the sprinklers will reach distances of up to a hundred feet. The word “Rotary” is indicative of the mechanically driven sprinklers getting a circular motion, thus reaching larger distances. This system waters a larger area with small amounts of water over a longer period of time.
Are very effective for delicate plants and high foot traffic areas. The water is forced through a small hole forcing the water droplets to mist up. This then settles directly on the plants and is absorbed. A mist pipe is ideal for greenhouses, slight or delicate seedlings, and special collector’s plants. They also stop people getting wet in nurseries or public spaces but still allow for the watering timetable to before filled.
This type of sprinkler is used for professional sports fields and it pumps volume. Life Sports Turf uses cannon sprinklers on professional soccer fields, rugby stadiums, and cricket pitches as the grass needs large volumes of water to keep it in tiptop condition. International stadiums tend to have bigger budgets too.
Center Pivot Irrigation
This is a form of overhead irrigation. Steel or aluminum pipes are joined together, supported by trusses, mounted on wheeled towers. The sprinklers are set on the length of the tower and that they move in an exceedingly circular motion.
What are the advantages of irrigation?
Larger yards take plenty of your time to water by hand, particularly if you grow fruits and vegetables. Looking at the plants you grow, they’ll like watering twice per week throughout the summer. putting in AN irrigation system could seem like an expensive endeavor, as well as the labor concerned, however, sprinkler or drip configurations have many benefits.
prevents Disease and Weeds
Specialized drip irrigation systems direct water specifically to each plant’s root ball, rather than sprinkling the entire garden like a typical rainstorm. As a result, surrounding weed seeds cannot germinate, therefore you’ll need less weeding to try and do.
Water at the roots additionally prevents leaf diseases caused by standing droplets on the foliage.
as a result of the water doesn’t strike the leaves or flowers, blight diseases don’t have any chance of proliferating.
Conserves Water and Time
When you are watering with a hose it can take substantial time and early morning and evening watering rituals deduct from family and work.
Either drip and sprinkler irrigation systems have timers, which will be planned for daily or weekly watering, so you do not have to monitor the watering as a result of the timer shuts the water off once it’s finished. Your water bill ought to be lower if the irrigation system is effective.
Preserves Soil Structure and Nutrients
Watering with a wide open garden hose may allow too much water to seep into the soil. As a result, nutrients leach out with the water runoff, leaving the plants with fewer nutrients available. The soil may also become compacted when you water with a hose Plants could show signs of withering or root sickness with breathless, compacted soil. Using either drip or sprinkler irrigation produces smaller droplets, serving to preserve nutrients and reducing soil compaction.
If you have a busy schedule, you’ll appreciate being able to work in the garden at the same time as the plants are being watered. While one garden section is being watered, you can plant and prune in another area.
