Tim Aquaduct-a je više od 20 godina na tržištu navodnjavanja u regionu. Do sada je projektovano i izvedeno 20.000 ha sistema za navodnjavanje. Stečeno znanje se prenosi na korisnike a svaki novi sistem sadrži u sebi sve prednosti i iskustva iz prethodnih.
The life of the irrigation system is made out of 3 phases:
- preparation and design
- building the system
- using the system
Treća faza, korišćenje i održavanje sistema za navodnjavanje je najbitnija i direktno utiče na proizvodnju obezbeđujući uslove za postizanje visokih i kvalitetnih prinosa. Domaćin-operater mora da poseduje visok stepen znanja o uslovima koji utiču na proizvodnju: klimi, vlazi zemljišta, poznavanju biljaka, organizaciji rada, poznavanju sistema, poznavanju procesa dodavanja hraniva kroz sistem za navodnjavanje (fertigacija).
For such a demanding task, good training of the operator is needed, a constant flow of information from the counsellor to the operator and disciplined control of the activities.
The condition in the field shows us that most of the knowledge that is missing is in the using and maintaining sectors of the irrigation system. The users are not trained enough regarding the possibilities and rules about the system they are controlling.
The basics of all decisions when working with the irrigation system is knowing the pressures, flow and time-lapse of some of the operations regarding watering and fertigation. The most important thing is that the system is set so that, an equal amount of nutrition is delivered to the plants that are nearby the equipment, as well as, those that are the furthest from it.
O upravljanju i održavanju sistema treba da se razmišlja prilikom pripreme – projektovanja sistema za navodnjavanje. Domaćin treba da zahteva od projektanta da mu obezbedi uniformnost navodnjavanja i adekvatne kapacitete sistema za fertigaciju. Oprema treba da ima mogućnosti da može da radi brzo, sa većim stopama ubrizgavanja u periodu sa više vlage u zemljištu, kao i kontinuirano, proporcionalno tokom letnjih meseci. Isporučilac opreme treba domaćinu da priloži ateste i karakteristike opreme koja se ugrađuje, a projektant treba da se saglasi sa kvalitetom opreme.
Before taking over the equipment the owner should get a manual for using and maintaining of the irrigation system with defined specifications of the built-in equipment and the starting parameters, as well as, using and maintaining procedures.
The irrigation system is maintained preventively – by performing regular activities during the system’s work:
- Controlling the work of the pumps
- Rinsing and controlling the work of the filters
- Rinsing the primary pipeline
- Rinsing the secondary pipeline
- Rinsing the lateral
- Controlling the work of the fertilizer solution injector and chemicals
- Controlling the work of the automatics
- Periodically, with special chemical treatments for chemical and microbiological maintenance
- Maintaining each part of the equipment specified by the instructions and recommendations of the manufacturer.
The user should be trained by the engineer and deliverer of the equipment about the ways of maintaining the system and its parts before using it.
For the systems maximal effort all factors that affect the production should be controlled. The knowledge of production, soil and irrigation system is a must-have alongside all of the factors and weather, for proper decision making of when and how much to water it.
It is most common for the amount of water, that is to be given to the plants, to be defined by a time-lapse (with droplets that have a ,,PC droplet’’ regulation of flow) 15 – 30 – 60 – 180 – 240… minutes, and not so much by the amount of water measured on the water meter. Basically, the same amount of water is delivered to the plants, but the only question remaining is tracking the work and analyzing the data at the end.
By defining the regime of work the characteristics of the system and fertilizer injection rate must be known. Only by knowing this and with regularly defined watering intervals can we secure uniformity of the water and nutrition distribution.
The most common problem of the exploitation is not knowing the specifications of the system which brings to a bad calculation of the fertilizer distribution. Owners seek solutions in the use of new automatic fertilization systems, hoping that the ,,smart’’ equipment can make the errors right again. This is the basic problem and delusion of most of the users.
If the operator doesn’t possess the knowledge needed for maintaining the drop-by-drop system with all the necessary information about the possibilities and intervals, there is no automatic equipment that can fix that.
If the basis is not set up right, no upgrading with automatic systems can help.
The solution of getting the exploitation system into the desired regime is in the next parameters:
- Analyzing the system
- Making a manual with the program of the work
- Educating the user
- Tracking the users and transferring knowledge until the moment the owner masters the knowledge and skills needed to regularly maintain the system on his own
For all these activities AQUADUCT DOO is at your service to check, instruct and transfer the necessary knowledge.
