Nutrients

It is essential to have a fertigation plan which avoids any stress to the plants and at the same time improves yield and quality.

The following factors determine the productivity of the crops:

Water

Fertigation is a term referring to the application of fertilizers dissolved in the irrigation water, which is applied directly to the roots of the plants via a drip irrigation system.

Crop Fertigation

Working with balanced fertilizer solution and pH, adjusted for each phenological stage of the crop, optimizes the efficiency of fertilizer application and improves the nutrients assimilation.

Optimum pH

It has been clearly demonstrated that a pH around 6 optimizes the application and absorption of fertilizers.

The establishment of the right frequency of irrigations and volume of irrigated water is essential for obtaining good results with hydroponics crops, both: in production and quality.

Because of its efficiency and simplicity the drainage control system is a great tool which helps with the proper management of irrigation of hydroponics crops.

Up to 5 drainage trays can be connected to the CDN and in this way the irrigation of every sector can be controlled independently.

Our drainage control system mixer adjusts perfectly the number of irrigations to daily fluctuations in water needs. It makes reference to solar radiation (an environmental variable) and to volume of drainage from the slab (a variable associated with plants).

Drainage control in hydroponics

Radio control valves

We have incorporated in our mixers the possibility of wireless irrigation valves activation, and we have achieved this without losing reliability! It is done by replacing the hydraulic micro-pipes and electrical cables with electronic field receivers which allow remote control of 2 or 4 irrigation valves each.

It can be used in anywhere, it is a practical and reliable solution, and when the distances are long, it also becomes very competitive in reference to price when comparing it to standard solutions.

Automatic control of soil moisture

The integration of soil moisture probes in our CDN fertigation system allows us to control the volume of water automatically in each irrigation which in turn allows us to optimize its efficiency.

By monitoring the readings from moisture probes we can establish an irrigation strategy, which is optimized to obtain the exact moisture necessary for the proper development of the plant.

Resuming, with such a system we can easily establish an irrigation strategy that optimizes the efficiency of every irrigation, being sure that plants are always at the optimal level of moisture needed for their development, which will directly affect the quality and performance of the production.

l Up to 10 CDN controllers can be connected to one PC. Through cable or via radio or wifi.

l We can also communicate with the PC located at the farm through our CDN Client application, simply by having a GPRS modem. And if access to Internet is available at the site - a remote desktop application can be used . 

With our CDN-PC software one or more CDN controllers can be connected to a PC via cable, radio or wifi and as such, these fertigation parameters can be easily managed.

CDN connection with PC and remote control from any location

It is possible to program in a very user-friendly way all irrigation settings from all fertigation mixers installed, and of course, in a much quicker way than by doing it manually. In addition, we can store all settings from the mixer and access it when needed.

The software creates various records and informs about performed irrigations, the consumption of irrigation water and fertilizers, readings and charts of EC, pH, temperature, solar radiation and all external devices which are connected to the system.Furthermore, it is possible to export data to text files or to Excel and use them to prepare personal reports, studies, etc.

And all this can be done remotely just by connecting to the controller using CDN-CLIENT software and GPRS modem or Internet connection.

With this software and a PC connected to the fertigation equipment, you can handle all fertigation parameters in a much easier and quicker way.

Fertigation management program CDN-PC

Our accumulated experience throughout the years has permitted us to develop specific applications for a wide range of crops, covering the requirements of the most demanding growers in each of their crops. Following our motto “equipment adapted to your crop” it is a principle which we permanently apply through the continuous improvement of our equipment.

Crops

Our fertigation mixers provide the accurate dosing systems and the most efficient control procedures.

Hydroponics

l Hydroponics crops or crops without soil require the adequate supply of all essential elements for the growth of the plant.

l The volume of substrate limits the amount of water available for the plant, as such it requires frequent irrigations at the right time.

l This growing technology needs a reliable control as it is very important to apply accurate amounts of fertilizers and water to avoid stress or lack of fertilizer.

High precision fertigation:With fertilizer flow-meters, the self adjusting dosefying system, which is continuously checking the dosed volume of each fertilizer and adjusting the possible deviations in order to guarantee the maximum precision at any time.Automatic irrigation:The adjustment of irrigation frequency and volume of water according to the needs of the crop is essential to reach the production potential. Drainage Control:Drain control, special devices such as WCM (Grodan), special applications developed by IFAPA and based on VPD combined with drain tray (exclusive system of INTA) .

Hydroponics

l Recycling of nutrient solutions:We have developed the most efficient systems for recycling solutions with the possibility of "premix" which will achieve a programmed EC level in the water. After this, we can adjust the final EC and pH of irrigation water with fertilizers. Preparing a new irrigation solution with clear water prevents the accumulation of certain salts.

Systems with mobile benches and recycling of nutrient solution. Also with sidewalk systems and flood irrigation.Control of different water sources mixing and disinfection systems.Irrigation of benches with irrigation booms.Fogging systems: high pressure, air-water type, low pressure, or any other which fits into the needs of your crop.

In this demanding sector we have accumulated a lot of experience in the 20 years of INTA existence.

Ornamental plants

Our fertigation equipment has the capability to control up to 320 solenoid valves and has the versatility to organize the valves in which ever way you want, allowing you to program up to 10 different fertilizer solutions.We can program the irrigation by fixed time or just by opening a valve manually, and the controller will choose automatically the fertilizer solution you have previously assigned.The fertigation mixer is ready to control irrigation booms. The fertilizer dosing in proportion to the main flow, gives the maximum precision even at very low concentrations.

Plant nurseries require different irrigation strategies than the rest of the crops. Because of that, we have introduced specific functions, which make the nursery’s irrigation management easier

Plant nurseries

Dosage of fertilizer in proportion to the irrigation flow from 5 fertilizer tanks (N, P, K, special treatments and pH). Reports including consumption of fertilizer and water for each irrigation. Solenoid valves controlled via radio, is a reliable and cost competitive system.Using soil moisture probes we can exactly control the volume of water needed and assure maximum efficiency in water use.It is also possible to use our software PC-CDN to set fertigation strategies.

With the objective to improve the use of water and fertilizer, we have developed systems, which permit to optimize the fertigation management of this crops.

Citrus, fruits, vineyards, olive trees

Using our fertigation systems you will be able to manage the fertigation and irrigation in your vegetable farms with the highest efficiency, saving water and fertilizer through complete irrigation strategies.With radio controlled solenoid valves system you can solve the problems of broken cables and microtubes, so common in so many crops due to intensive machinery work, and this can be done at a very competitive cost.With INTA fertigation systems, based on circular multi-venturis and electronic fertilizer counters, you can produce higher yields, improving the quality and as a result get high profitability on your production.

Vegetable crops

The dosage of fertilizer incorporated into the irrigation water (fertigation) and control of pH are tools that improve considerably the results of traditional technologies.

Golf Courses

l By controlling the pH in the irrigation solution we improve the uptake of nutrients by plants. Our mixers are equipped with dosing pumps that are resistant to corrosive solutions.

l Better control of fertilizer dosing, due to it’s ability to adapt to the circumstances of the moment.

l With fertigation the use of heavy machinery for the distribution of fertilizers is no longer necessary.

l Better grass growth, faster recovering and uniform color, more evident when the water quality is not the desired.
