From soil to soilless
As the soilless cultivation trend expands, the need for controlled precision irrigation and fertigation is highlighted. Having no soil buffer, the soilless substrate needs careful dosing of nutrients, effective and frequent drainage, and a low flow supply of water. This will ensure consistently high yields and high-quality crops.
Since pioneering drip irrigation in 1965, Netafim has been the global precision irrigation leader. Today, we offer reliable and flexible irrigation systems for greenhouses that deliver water and nutrients according to a plant’s specific needs. It’s one of our unique strengths. In fact, over 60% of high-end greenhouses all over the world are installed with Netafim trademark PCJ-CNL drippers.
Saving water and preventing land contamination
A modern greenhouse is highly sustainable and advanced in terms of its water usage.
In greenhouses, we constantly recycle about 20-30% of the water used for irrigation, disinfect it and then mix it with fresh water from an external source. This reduces water use but also fertilizer use – as the recycled water retains nutrients from one cycle to the next.
Drain water is recaptured and disinfected by a UV treatment. These solutions are simple to apply once installed and require very little maintenance. Reusing the drain water prevents land and water contamination, as fertilizers are not released into the ground and groundwater.
INNOVATIVE HEATING SOLUTIONS
Greenhouses are energy-intensive, and that energy can be expensive. In certain climates, this can have a remarkable impact on the profitability of your greenhouse.
So, one of the key factors in your greenhouse projects is finding the most secure, sustainable and energy-efficient heating solution that will deliver ideal growing conditions.
“We helped one of the largest supermarket chains in Croatia grow tomatoes all year round, using solar power and biogas from the neighbouring dairy farm to heat up the greenhouse and create a model for ecologically-advanced and secure production,” recalls Ofer Inbar.
