SeedCare from Oosterleek uses bioreactor for clean water

Healthy water is essential for Mark Cologne of SeedCare, seed production company. He has had an Agrona bioreactor on his farm for five years now, which provides clean water with good bacteria, giving him more resilient plants.

Tomato grower sees: more oxygen, more fruit, and a clean silo

Paul van Paassen, with 2.2 hectares of glass, has invested in his irrigation water quality and Oxybull, Agrona's aeration system, in recent years. This is now paying off in vital roots and healthy plants.

Better roots and cleaner water with an aeration system

Agrona's OxyBull aeration system ensures an optimal oxygen concentration in the water and root environment. XL Bloom Youngplants in De Lier has been using the OxyBull since March. Powerful pump with a capacity of 60 m³/hour blows a lot of air into the water, causing a lot of movement in the water.

Increased oxygen improves strawberries' rooting

Agrona's OxyBull aeration system ensures an optimum oxygen concentration in strawberries' water and root environment. In the Netherlands, greenhouse strawberry company Dutch Berries has now installed a third system. The aeration system now boasts an oxygen sensor. It continuously measures the basin or silo water's oxygen content. It does so by linking to the climate computer.

OxyBull moves water throughout the water storage tank

Agrona's OxyBull aeration system provides crystal clear and healthy oxygen-rich water at VG Orchids in De Lier. The aeration system has been expanded with an oxygen sensor for continuous oxygen measurement in a basin or silo. By connecting to a climate computer, the grower can monitor the oxygen content.

Better root hairs and cleaner water with OxyBull aeration system

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.

Oxygen gets rid of algae

“At first, the filters silted up with algae every few days, now we practically no longer need to clean them. In addition, the root development is very good. We see a lot more roots and practically no more dead material. "

Wet Novelties At Renewed HortiContact

Just a small hour and HortiContact 2020 will show it's new fair. Water remains an important theme at the fair. Their renewed machines are presented by Ridder and Agrona, among others.

More Bacteria Can Also Mean More Stable Growth

It was long thought that bacteria had to be fought, but it is now clear that this idea is wrong. According to Nadir Laaguili of Agrona, it is not about fighting bacteria, but about finding the right balance. The company has developed a plug-and-play nursery for beneficial aerobic bacteria.

New Step Taken For Better Water Quality With Aeration System

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.

Water Handling Application Takes Care For A Constant Optimal Oxygen Level

Sufficient oxygen in the water and root environment is a prerequisite for a strong and vital crop. More oxygen makes the crop stronger and ensures higher production. That is the experience of Van der Voort Tomaten in Vierpolders. The company uses an Agrona water treatment system that permanently maintains optimal oxygen levels.

Bioreactor For Clean Water And Drip System

SeedCare in Oosterleek, North Holland, produces 40 different crops of seeds for national and international companies under 2 hectares of glass. The vegetable crops, such as cucumber and tomato, are grown in the ground. The potted plants are on permanent cultivation tables. The crops are watered as needed, so there is no drain or drainage water. 

Improving The Plants Root System With Extra Oxygen

A high oxygen content in the water is of great importance for the development of plants. To realize an optimal oxygen supply, various vegetable companies in greenhouse horticulture use the OXYBULL aeration system. The system ensures that the concentration of oxygen in the water and root environment is optimal. 

Water Handling Application Takes Care For A Constant Optimal Oxygen Level

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.”

Mineral uptake

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.

No More Polluted Silos In Horticulture!

Water silos in horticulture are necessary for every grower. The large amount of water storage is necessary for the crop and every company has one too. It goes without saying that silos also become contaminated and bacteria, fungi and algae end up in the water, which is detrimental to the oxygen level and water quality. A low oxygen level has an adverse effect on the crop and a contaminated silo has an adverse effect on drip lines for the silo itself. Plants need good water with enough oxygen to grow vigorously. Standing water does not help with this. But what can you do about stagnant water?

Why An Investment In Water Quality Is Necessary For Horticulture

One of the most important carriers that the crop needs is water. Water ensures that the plant can grow and stay healthy. This seems obvious, but the water quality at most growers is certainly not optimal. As a result, a lot of algae will develop, more dirt will remain in the water and fungi and bacteria will have the chance to damage the crop. Furthermore, drip lines are affected and become polluted.
