A Sicilian grower's irrigation water contained only 6 ppm of oxygen, which dropped as low as 3 ppm at the drippers. The result, especially during the hot summers in southern Italy, was crop losses reaching up to 20%. For grower Andrea Ferrera, this was reason enough to invest in a nanobubble system.

Stoffels Tomaten has experienced some difficult years in recent years, including root problems and virus problems. In search of improvements, the water system was thoroughly overhauled. “We have actually done three things, of which the investment in nanobubble equipment is the most striking,” says Paul Stoffels.

Since pepper grower Arthur Mooijman has focused on resilience, his plants have remained more vital and are less affected by diseases and pathogens. Since the commissioning of a bioreactor that aerates and microbiologically enriches the irrigation water, these effects are even more noticeable. “Plants benefit more from oxygen-rich water with good micro-organisms than from sterile water,” he says with conviction. “I no longer have root diseases and my plants are clearly more vital and stronger.”

About six years ago, pepper grower Arthur Mooijman decided to invest in a plate aeration system due to algae problems in his water tank. Now that Mooijman has a greenhouse in Berkel en Rodenrijs since 2021, he has also started investing in this location. Since March of this year, an Oxybull system from Agrona has been operating here as well. Additionally, the grower also utilizes an ABR Bioreactor.

Life Sciences Review: Agrona belongs to the top 10 biotech horticultural companies. Traditional methods of cultivation in the horticultural sector are based on climate, but the focus is now also shifting to improving water quality. However, most water disinfection methods eliminate all bacteria and fungi, including those that are good for soil health.

The main majority of horticultural crops are on substrate. With that you can steer the fertilzer very well. Strangely enough, however, we do not make optimal use of this in horticulture. We systematically give an oversupply of water and fertilizers. Nobody knows exactly what the effect is. There are indications. Nitrogen, for example, mainly stimulates leaf and stem formation. A smaller supply would be good for flower formation and setting. But managing this requires that you can measure precisely the needs of the plant and the levels in the nutrient solution from day to day. And much more insight than we have now. Methods are gradually being developed to adjust the mineral supply more to the needs of the plant.

You do not replace a “tricky” pepper gutter that does not make it possible to drain from the side. In order to take steps with the oxygen content in the mat and thereby prevent root problems in the course of cultivation, Personal Vision chose to work with an aeration system. “An hour before the first watering, the Oxybull ensures that the oxygen level in the drain silo is back up to standard”, says cultivation specialist Roel Klapwijk of the company that grows red block peppers on 7 hectares in Bleiswijk.
