Presentation on control software for general irrigation and fertigation, INTA CDN system

2. Crop Fertigation
The goal of any agricultural company is to maximize its
economical profits, which can be done through the
efficient use of water and fertilizer.
The following factors determine the productivity of the crops:
Water
Nutrients
Soil / substrate
Cultural work
Genetic
Environmental
(Light, CO2,
Humidity and Temperature)
It is essential to have a fertigation plan which avoids any stress to the
plants and at the same time improves yield and quality.

3. Crop Fertigation
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.
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.

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

5. Our Systems

11. Drainage control in hydroponics
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).

12. 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.

13. 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.

14. CDN connection with PC and remote
control from any location
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.
Up to 10 CDN controllers can be
l
connected to one PC. Through cable or
via radio or wifi.
We can also communicate with the PC
l
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 .

15. Fertigation management program
CDN-PC
With this software and a PC connected to the fertigation equipment, you can
handle all fertigation parameters in a much easier and quicker way.
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

16. Crops
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.

17. Hydroponics
lHydroponics crops or crops without soil
require the adequate supply of all essential
elements for the growth of the plant.
lThe volume of substrate limits the amount
of water available for the plant, as such it
requires frequent irrigations at the right
time.
lThis 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.
Our fertigation mixers provide the accurate dosing systems and the most
efficient control procedures.

18. Hydroponics
lRecycling 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.
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) .

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

20. Plant nurseries
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
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.

21. Citrus, fruits, vineyards, olive trees
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.
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.

22. Vegetable crops
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.

23. Golf Courses
The dosage of fertilizer incorporated into the irrigation water
(fertigation) and control of pH are tools that improve considerably
the results of traditional technologies.
lBy 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.
lBetter control of fertilizer dosing, due to it’s
ability to adapt to the circumstances of the
moment.
lWith fertigation the use of heavy machinery
for the distribution of fertilizers is no longer
necessary.
lBetter grass growth, faster recovering and
uniform color, more evident when the water
quality is not the desired.
