In the image we can see an example of buried TERRAM pipe in citrus cultivation.

TERRAM (0.60 distance between drippers / 2 liters) at a depth of 30 centimeters.
0.60m / 2l Localized irrigation has the disadvantage that the dense network of pipes located on the ground makes many agricultural tasks difficult, especially those that use machinery: work, treatments, harvest, etc.
The normal thing is that, for some of these works, the dropper-holder branches are collected, which implies an important cost in labor and collection and extension equipment, as well as in warehouses or places to store the pipes.

Therefore, the idea of ​​underground irrigation is very attractive, since all the pipes, even the lateral ones, remain buried, without the mentioned inconveniences.

ADVANTAGES IRRIGATION BY UNDERGROUND DRIPPING
– Savings of personnel and equipment in the management.
– Longer duration of the installations, which are not damaged by the action of solar radiation and suffer less attacks.
– Increased irrigation efficiency. Because the emitters are buried, we avoid that the water is on the surface of the soil exposed to evaporation, that is, better distribution of water, less runoff, greater uniformity. In addition, it is closer to the roots that absorb the water necessary for the growth of the plants, often we can see in the surface located irrigation the water moving outside the area next to the plants. The increase in efficiency in relation to surface localized irrigation is very variable depending on the application in question and the system with which it is compared.

– Better assimilation of nutrients. In the case of non-mobile elements such as phosphorus or potassium, we place them at the root’s disposal.
Levels of leaching of minor nutrients are also given. In any case, it is always advisable to use balanced nutritional solutions that are dosed continuously.
– Decrease in the presence of weeds. The soil surface remains dry and therefore the germination of weed seeds decreases considerably. It has a direct impact on saving herbicides and labor.
– Decrease in fungal diseases. We avoid moisture at the base of the plant, in leafy vegetables such as lettuce, celery, etc. we avoid wetting the leaves of the base. In addition, we can apply systemic fungicides through the irrigation system increasing its effectiveness.

– Facilitates the work of the soil. In crops that require weeding or superficial tillage of the soil, we eliminate the obstacle of the superficial dripper line. Even in horticultural crops, if we bury the dripper lines at a certain depth, we can till and prepare the soil for the next crop several times with the consequent saving.

When the operation to bury the portagoteros lines is very simple, carried out with a plow mole or with a device incorporated in the implement used to form the cultivation sidewalks.

– We avoid problems of vandalism and improve the duration of the pipes. It is obvious that when buried the pipes are much more protected from the aggressions and the sun.

DISADVANTAGES IRRIGATION BY UNDERGROUND DRIP

The main drawback, by far, is the sealing of the drippers, which can be produced either by particles transported by the water or by the roots of the plants or trees.

In GESTIRIEGO we have the most advanced technology to solve these problems. In the case of particle sealing, we have an anti-siphon or anti-siphon system, which blocks the aspiration of particles from the ground, at the time of installation stoppage and emptying of the pipes, as well as a self-cleaning system.

At the moment of self-compensation, a vibration of the membrane occurs, preventing the incrustation of particles inside the emitter. In the case of root seals, after 4 years of research and more than 8 years of experience in various crops, we have reinvented underground irrigation, creating and patenting a repellent root system incorporated in the dropper that is released slowly, as long life of up to 10 years, in small doses, preventing the roots from approaching the vicinity of the emitter.
