Drip Irrigation
An irrigation system may use valves to separate fields into zones. This allows a limited water source to provide water to a large area by water- ing one part at a time. Drip irrigation systems can operate by gravity. This system is inexpensive but it can irrigate only a small plot of land 35' x 35'.
Unfortunately, flood or surface irrigation is the least efficient method. It's because it delivers more water than the plants need. Much of the water is lost as it evaporates into the atmosphere, while that which is excess to the plants' requirements percolates down to groundwater.
The drip irrigation system is comparatively cost-effective. Yet, the price may vary depending on the quality of the products, installation charges, size, types, and more.
Drip or trickle irrigation is one of the most efficient irrigation systems. It minimizes wastage of water by supplying the amount of water required by the plant directly to its roots.
Merits: Well is simplest, cheapest and independent source of irrigation and can be used as and when the necessity arises. Several chemicals such as nitrate, chloride, sulphate, etc. found in well water add to the fertility of soil.
Drip irrigation is the most efficient irrigation system because it delivers water directly to plant roots, minimizing water loss. Flood irrigation is the least efficient due to high evaporation and runoff.
Wet pipe sprinkler systems are the most reliable and cost effective. Therefore, they should be the first type considered when selecting a sprinkler system. However, there are times when a wet pipe sprinkler system may not be appropriate.
Drip irrigation is a very efficient way to irrigation crops and has the advantage of lower evaporation than other irrigation methods, it is the most common type of "microirrigation." Drip irrigation is one of the more advanced techniques being used today because, for certain crops, it is much more efficient than ...
Budget: Drip irrigation may have higher installation costs, but it can save money in the long run due to its efficiency. Sprinkler systems are more affordable upfront, but their ongoing maintenance costs may add up.
Subsurface drip irrigation is a modern and sustainable irrigation system that applies water directly to crops' root zones using buried drip lines or drip tape. In this irrigation method, the drip tubes are buried under the soil surface rather than on the ground.
One peculiar disadvantage to drip systems: gardeners often replace plants that have died at the end of a drip system tube by placing a new plant in the exact same place as the existing tube end – regardless of the type, needs, or eventual size of the new plant.
The correct answer is Drip Irrigation.
Surface or flood irrigation is the least efficient manner of irrigation. When a field is flooded, more water than is needed by the plant is applied to the field and water evaporates, seeps into the ground and percolates down to the groundwater, where it can be out of reach of the plant's roots.
The best way to water your lawn without a sprinkler system is with a hose and watering nozzle. This system works especially well for smaller yards with less surface area to cover. Watering the lawn deeply by hand once or twice a week helps keep your grass hydrated and healthy.
A low-cost irrigation system can be as simple as a series of troughs or gutters moving water by gravity, or it can involve a pump and pipelines to move water to sprinklers or a drip system.
Final answer: The most efficient method of irrigation is drip irrigation.
“Rotary sprinklers will be the most water-efficient, while self-propelled sprinklers will often save the most time and effort,” says Cosby. Again, the most efficient lawn watering system for you depends mainly on the size of your garden.
Unlike other forms of irrigation, such as sprinklers that are only 65-75% efficient, drip irrigation 90% efficient at allowing plants to use the water applied. And, it reduces runoff and evaporation. Drip irrigation applies the water slowly at the plant root zone where it is needed most.
Wet pipe systems
Since they are simple, they are also very reliable. When an automatic sprinkler is exposed for a sufficient time to a temperature at or above the temperature rating, the heat-sensitive element (for example a glass bulb) breaks, allowing water (held under pressure) to flow from the sprinkler.
The drip method of irrigation is the best among all modern methods of irrigation.
Clogged Emitters – It's common for drip emitters to become clogged from mineral/chemical deposits, or algae and bacterial buildup. Even plant roots can find their way into drip tubing. If clogs are not cleared right away, water pressure can build up and cause damage to the system.
