Do you know how to choose a drip irrigation system?
In Gestiriego we have been manufacturing these systems for more than 30 years, so we put at your disposal this explanation so you know how to choose a drip irrigation system.
We find different solutions, depending on what needs to be irrigated, whether they are pots or large hectares of crops, they are distinguished mainly between two forms of installation: surface and underground.
The underground facilities, unlike the superficial ones, are usually installed at 50/60 cm from the underground plant, with this we achieve a higher root growth and a better conservation of the water underground. This type of installation is usually done in trees or in very dry climates. The underground facilities are usually made in horticulture and thinner and thinner pipes can be used that will go through the surface soaking the soil drop by drop.
TYPES OF DRIP IRRIGATION SYSTEM
Depending on the way of supplying the water, there are drippers with constant flow (self-compensating), adjustable and micro-sprinklers. The dropper must be chosen according to the water needs of each plant, the characteristics of the soil and the size of the drip system.
• Dripper with constant flow: They are not adjustable and always provide the same amount of water. They are ideal for plants that always need the same amount of water, which are usually the specimens of adult plants. This type of dropper is the simplest and most economical.
• Self-compensating dripper: They are drippers of constant flow (not adjustable) able to compensate the pressure differences, to guarantee the same flow. It is recommended when the drip pipe has a length of more than 25 m, or when there are significant differences.
• Adjustable dripper: This type of dripper allows the flow rate to be adjusted up to 60 liters / hour. They are specially designed for growing plants or for places with very changing temperature and humidity conditions.
• Micro sprinklers: Your irrigation is in the form of very fine rain. These micro-sprinklers project a very fine drop (they even work as nebulizers) and water in a radius of up to 5 m. When this type of irrigation is used, one must be careful with the irrigation schedule to avoid the plants burning with the sun.
• Conventional polyethylene pipes are those that work with drippers.
– The great advantage, compared to other types of pipes (such as porous or with integrated drippers) is that they allow each dropper to be placed in the exact place that is needed, thus making the most of the water and irrigating it with precision.
– You can attach and combine different types of drippers or even microdifusers, according to the water needs of each plant. The choice of diameter depends on the number of irrigation points that are needed, the extension that must be covered and the characteristics of the terrain.
The most common diameters are:
– Diameter 4 mm. This thin pipe is perfect for composing a small drip irrigation system: up to 12 pots or 15 linear meters. It is also used for the branches in thicker pipes. – If you are dealing with pots, you usually place a dropper in each one. If they are large planters or pots, it is preferable to place two.
– Diameter 16 mm. This diameter is one of the most used since it allows to compose systems adapted to any type of crop.
– The drippers can be placed directly in the pipeline, or branches and branches can be connected to plants and areas further away or that are at different levels by means of a microtube and are buried with stakes.
In addition, in Gestiriego you can get the materials to manufacture a conventional drip irrigation system:
• Pressure reducer: Drip irrigation emitters (drippers) do not need just water pressure to operate. Too much pressure could make the drippers jump.
• Filter: This element is optional, but we recommend using it since the filter prevents the lime or debris from accumulating and clogging the pipe or drippers. In Gestiriego you can find the MXFILTER filters.
• Pipe: It can be installed in different thicknesses, but the most common is the 16 mm diameter.
• Connection pieces: T-shaped supports, such as links, stop valves or elbows, and clamping devices, such as staples, supports or guides.
• Drippers: Also called emitters. They receive the water from the pipe and supply it to the plant drop by drop.
• End cap: As the name implies, it is placed at the end of the pipe.
But most important, what are the advantages of drip irrigation?
• A drip irrigation system allows greater water savings, since it supplies each plant with only the amount of water it needs. It is also proven that it benefits the development of the plant.
• There is no ponding in the plant. In this way, the appearance of rottenness and the proliferation of fungi is prevented. In addition, the loss of nutrients is avoided, usual in excessive irrigation.
• It favors the formation of a pivoting root, that is, elongated and downwards. In this way, the plant easily accesses the water and nutrient reserves. Pivoting roots absorb and reserve water better.
• It works with low pressure, therefore a pump is not needed to drive the water. Maintenance is simple and cheap.
• The drip irrigation also helps to have less presence of weeds, since the surface hardly gets wet. Do not forget to visit our products section to see our wide variety of pipes, accessories, filters …
