I recently came across this discussion about drip irrigation among a group of growers at the Russell Ranch Field Day.
While all the growers expressed their satisfaction with the benefits provided by drip irrigation, such as higher yields and efficient use of water resources, some of them raised concerns regarding dripper clogging problems.
Now, I am certain that in this case they were not using Netafim’s products, because at Netafim we addressed the clogging issue problems more than 35 years ago. In fact, to illustrate this, I always give as an example our own Jojoba field near our Kibbutz, Hatzerim.
Clogging prevention of our sub-surface drippers in our Jojoba field
In Kibbutz Hatzerim, where Netafim introduced drip irrigation 45 years ago, we irrigate a 400-hectare plot of Jojoba, with our subsurface drip irrigation system.
The plot utilizes one dripperline per row of plants, and the drippers are spaced one meter apart from each other.
The water used for irrigation is recycled wastewater from the Kibbutz and from Beer Sheva, a nearby city.
This means that not only have the drippers been buried underground for over 10 years; the water that passes through them is quite challenging and prone to clogging.
Thanks to Netafim’s special labyrinth structure (Turbonet™) and anti-siphon mechanism, the system has not been clogged and is today as accurate as on day one.
Netafim’s pressure compensated drippers (PC) and dripperlines feature continuously self-cleaning, thus avoiding clogging.
There are several algorithms built into the little dripper, ensuring that:
- Pressure regulating mechanism ensures that each dripper provides the same flow, regardless of inlet pressure.
- Each dripper has a built in large filtration area.
- An ongoing cleaning mechanism uses pressure to push out dirt particles.
- Mechanical root barrier prevents root intrusion
- Anti-siphon mechanism prevents suction of dirt particles
- Non Leakage mechanism keeps the water in the system once it is shut and prevents uneven drainage
- Membrane, structure and materials that withstand chemicals, acid and extreme climate conditions
These algorithms are protected by several patents registered all over the world.
With Netafim, the grower can enjoy the benefits of drip irrigation that were discussed in the panel, without any of the drawbacks that were presented.
