Agrona's OxyBull aeration system ensures optimum oxygen content in the water and root environment. XL Bloom Youngplants in De Lier has been using the device since March of this year. A strong pump with a capacity of 60 m3/hour blows a lot of air into the water, so there is plenty of movement.
In about an hour, the renewed HortiContact 2020 will start. Water remains an important topic at the fair. Ridder and Agrona, among others, present their renewed machines. Furthermore, more organic crop protection options thanks to extensions of the label at Biobest.
It was long thought that bacteria was something to combat, but now it is clear that this idea isn’t true for horticulture. According to Nadir Laaguili of Agrona it is not about combating bacteria, but about achieving the right balance. For this, the company developed a real plug-and-play nursery for beneficial, aerobic bacteria.
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.
Enough oxygen in the root-environment is a condition for a strong and healthy cultivation. More oxygen makes the cultivation stronger and leads to higher productions. That is the experience of Van der Voort Tomaten in Vielpolders. The company uses a water handling application which keeps the oxygen level optimal.
Seeds growing company SeedCare in Oosterleek, North Holland, produces under 40 hectares of glass. They have as many as 40 different crops of seeds for national and international breeding companies. The vegetable crops, such as cucumber and tomato, are grown in the ground. The pot plants, including cyclamen, primula and begonia, stand on fixed cultivation tables. The crops get water as needed, so there is no drain or drainage water. The company does not recirculate the water.
A high oxygen content in water is essential for the development of plants. In order to realize an optimal oxygen input, various vegetable companies in the glasshouse horticulture use the OXYBULL aeration system. The system ensures that the concentration of oxygen in the water and around the root environment is optimal. Combined with oxygen meters, the oxygen level on the computer can be represented in a graph.
Then it’s a matter of how to get that right amount of oxygen in the water. For this purpose Agrona developed the Oxybull aeration system. “For this system we have developed a membrane cloth that creates miniscule bubbles in the water basin”, Nadir says. The installation was super easy, adds Frans. “No adjustments to the silo are required and the silo only needs to be partly emptied once (half a meter of water may remain in the silo) before installation. That is all. From then on you do not have to worry about it anymore.”
