A drip irrigation system consists of long tubes fitted with emitters. Secondary tubes branch off a main water line, which may be connected to a tap fitted with a pressure regulator, filter, and backflow valve. Drip systems are usually made from polyethylene plastic and are widely available from irrigation suppliers and hardware stores. Different types of drip irrigation include:
1.Drip tape: This flat-style tubing requires a pressure reducer in the waterline to function optimally. It works well for subsurface installations, but isn’t usually manufactured to last more than a few seasons.
2.Drip line: This round tubing is manufactured with heavier duty plastic that will function well for multiple seasons. You can purchase drip line with pre-installed emitters (best for crops planted at regular intervals) or separate emitters that you install yourself (ideal for customized spacing).
Drip irrigation systems deliver water directly to the base of your plants, meaning that little is misdirected or lost to evaporation. Since they generally water slowly, over a long period of time, the water penetrates over a broad radius and deep into the root zone.
Drip systems consist of several components, all of which are easy to install. You can also configure your system to target certain areas of the garden while preventing flow to others. This means you can water different zones at the same time, making drip irrigation a good choice for large gardens with areas that remain fallow early or late in the season.
If you garden on a slope, you can install pressure-compensating emitters to ensure all areas of your garden receive equal amounts of moisture, no matter how hilly. You can also choose customized emitters to work with your garden’s soil type.
If you inadvertently stab part of your drip system with a digging fork, it’s easy to repair and reconfigure by purchasing replacement parts. Splicing and fixing usually requires no specialized tools.
Drip systems work well on timers and can easily be scheduled to operate in the middle of the night in hot climates, when evaporation is least likely to occur.
The emitters on drip systems can become clogged over time, requiring periodic inspection and some maintenance.
In some systems, wind can misdirect the moisture from drip irrigation, wasting water and missing the desired ground area to be wetted. You can avoid this by not watering in strong wind and by ensuring your drip line is flat on the ground and designed to drip rather than spray.
Drip systems usually involve a healthy up-front investment. They also take time and planning to set up.
