Keys to adapting water filtration for irrigation and fertigation in greenhouses High-precision filtration plays a fundamental role in water quality for drip irrigation, micro-sprinkler, and fertigation systems in greenhouses, particularly when it comes to preventing blockages and maintaining system efficiency. The goal should be to find the right balance between protecting the emitters and the operational efficiency of the system." "At STF Filters we offer solutions with filtration grades ranging from 10 to 1,000 microns, which allows us to cover the typical requirements of greenhouse irrigation systems," they note.
"In these cases, it may be advisable to incorporate automatic two-stage systems, combining a first physical filtration stage using a screen filter with a second disinfection stage using ultraviolet light, as in our FMA7000UV model." "This type of filtration-plus-disinfection solution can also be used in installations where regulations require certain reject waters to be treated before discharge or reuse. "Equally, it is necessary to establish a proper maintenance program that includes periodic flushing of the network and control measures to address the development of biofilm, algae, and bacterial activity inside the pipework." © STF Filters Irrigation uniformity starts with protecting the emitters When filtration is correctly designed, each emitter can operate under the intended conditions and deliver the flow rate for which it was designed.

Why this matters: For operators, this is a water-management story. The useful signal is that direct substrate measurements can help cut drain loss materially without giving up yield or fruit quality, which is exactly the kind of controllable efficiency gain a facility can build on.
Frequently Asked Questions
Why does substrate sensing matter in free-drain strawberry systems?
Because drain percentage tells a grower what already happened, while substrate moisture and EC data show root-zone conditions directly. That makes it easier to cut water loss without guessing.
What is the operator takeaway from this trial?
If the thresholds are understood well enough, growers can reduce drain water materially while protecting yield and fruit quality, which makes sensing an operational tool instead of a reporting tool.
