There are several approaches to RGS depending on the differenttypes of crops to which we apply it and according to the useful life of the system, which is related to that of the crop
SUB-SURFACE DRIP IRRIGATION in Woody Crops and its Application
The vine and the olive tree are the two pioneer crops in Spain and the ones that occupy more cultivated areas of this system worldwide; more than 100,000 hectares planted with the RGS system
Currently, the crops where the Sub-SURFACE DRIP IRRIGATION (SDI) system is being implemented the most with great benefits and yields are nuts, such asalmonds, walnuts, hazelnuts and/or pistachios.
 
Thecherry, peach, apple and pomegranate trees are some of the fruit trees that have been incorporated later, but have begun their journey. The same is true of theorange and lemon treesin eastern Spain that are also facing water shortages, and where the RGS is the ideal system to combat this situation
SUB-SURFACE DRIP IRRIGATION for extensive crops and its application
Extensive rotational crops and long life facilities:
These are installations with a long useful life (>20 years) that use an Irrigation system through High Thickness, pivot or total coverage sprinkler piping, where rotations are practiced withlegumes, cereals, sunflower, and even alfalfa cycles they are designed to provide a safe and secure environment for thefull wet coverage, sow independently of the installation and achieve trouble-free germinationbecause the humidity of the surface can reach 100%
.
 
Extensive crops without half-life rotation:
In order towetting specific areas of cultivated soil without seeking nascencefor crops with a strong root system, such as maize, asparagus, sorghum, sugar cane, etcalfalfa and sugar canedripline, the use of mediumwall thickness emitting pipes requires a lower level of investment than heavywall thickness pipes
Annual horticultural crops:
It is used in thousands of hectares of annual vegetables such aslettuce, tomato, potatoes and artichokes. The RGS system in these crops is verysimple to implement, economical and significantly improves yields.

SUB-SURFACE DRIP IRRIGATION in gardening and landscaping and its application:
We have many years of experience in the installation oflawns, hedgesand medians of all types of plantsornamental shrubs and trees.
Benefits of Sub-Surface Drip Irrigation in current agricultural trends The main advantages of Sub-Surface Drip Irrigation (SDI) vary depending on the approach to each crop and the growing area, but we can divide them into two blocks of benefits: environmental and cost-effectiveness
Environmental benefits of RGS:
- Water savings: Considering the increasing scarcity of water resources, this is the main advantage of this Irrigation system.
- Fertilizer savings: The system allows the right amount of fertilizer to be applied to the plants at the optimum time. This is the best way to optimize fertilization without contaminating the soil and subway aquifers.
- Herbicide savings: Cover crop farming is growing and the ability to control weeds is one of the main reasons for choosing RGS, as it facilitates clean-up work without damaging irrigation systems.
- Savings in phytosanitary products: Irrigation at depth reduces moisture at the soil surface, which reduces the use of crop protection products for crop diseases.
- Use of wastewater: The possibility of using these waters with total food guarantee.
Advantages of RGS in terms of profitability:
With RGS, profitability is enhanced by optimizing costs and improving production performance.Farmers using AZUD's RGS system reflect real cost and yield savings data over the yearsof which the following are worth mentioning
- Water savings by 30-40%.
- Fertilizers savings by 10-30%.
- Phytosanitary treatment methods are used less frequently.
- Phytosanitary treatment methods are used less frequently.
- Use of less herbicides.
- Phytosanitary treatment methods are used less frequently.
- Reduces installation maintenance, because rodents, hunters, etc. interfere less.
- Yields in the binomial (Kg production / m3 water consumed by the Irrigation system) higher.
Other major advantages:
In the case of nuts, since many users prefer to pick the fruit from the ground, the SUB-SURFACE DRIP IRRIGATION is the only system that can be used for the production of nutscan do so without interfering with the process and allows it to be carried out more efficientlythe main reason for its choice
On the other hand, with alboom in organic farming and minimum/zero tillage with always direct farmingrGS is a system that is much better adapted to this type of agriculture as it does not use herbicides, improves soil Frame with capillary irrigation, the possibility of including organic fertilizers, etc. The development of the RGS system has been a key factor in the success of this type of agricultureagricultural technologyapplied to the system allows users to avoid the fear of “not seeing the irrigation water”. Advances in Irrigation automation and humidity sensors haveimproved RGS control and management. Thanks to the development of specific technical products applied to the RGS, to the references for thousands of hectares and different crops, to the management of thousands of users worldwide, to the “know-how” of its use of companies such as AZUD and with the trend towards water scarcity, the Sub-SURFACE DRIP IRRIGATION is positioned as an irrigation system with a long way to go and, in many cases, as an irrigation system with a long history and, in many cases, as the most efficient onethe best Irrigation alternative.
