About Agrona

The Growth Specialist

Agrona is a Dutch producer specialized in water treatment systems and bio-stimulants for agriculture and horticulture. We offer specialized knowledge and safe solutions that improve the health, resistance and productivity of crops. Our products have already proven to be successful in improving soil life and resilience.

We are reliable, offer no-nonsense, realistic solutions and are happy to communicate in an open and personal way. We distinguish ourselves with our special water treatment systems and biostimulants for agriculture and horticulture. These ensure that crop vitality is improved.

Combining traditional mineral fertilizers with our bio-stimulants is the future. We help you to grow your crop to the limit. We work together with local partners and work close to our customers. Agrona is based in Berkel en Rodenrijs (ZH) and works internationally. We are active worldwide with our headquarters in the Netherlands and subsidiaries in France, Spain, Canada and Mexico.

Why Agrona?

The water treatment systems of Agrona increase the oxygen content in the water and around the root system. Our high-quality biostimulants increase resilience and stimulate soil life. More oxygen means more production!


Growers still appear to underestimate the disease pressure from the drippers or the total watering system. pathogens also develop in the water system that you are not waiting for. Organisms extract oxygen from their environment, which can lead to an anaerobic situation in the irrigation system. Especially in the autumn (due to a longer time between the drips) and in the summer (due to a high water temperature) this situation can occur in which the pathogens start to dominate.

Improve soil life

A popular product of Agrona is the organic product AG STIM. This product converts organic matter into anorganic matter. This keeps the pipes clean. AG STIM also stimulates the growth of beneficial bacteria that improves soil life. AG STIM improves the resistance of the plant against fungi and bacteria. The result is more nutrient uptake and a healthier and stronger crop. All you have to do is check the irrigation system and flush it.

The Tipping Point

The turning point from aerobic to anaerobic can occur within a few hours. It is not hard to imagine what happens when a system (after the last turn) just stands still for 12 to 16 hours until the next morning or the water temperature is 26 degrees. In addition, the pH in the system drops. Sometimes the difference between the unit and the drippers increases by 1 to 2 points. This is also not favorable for the development of the roots. Many growers try to anticipate with a gift of disinfectants or give a higher dose before the night. They always check the ppm's from the drippers to prevent them from knocking over with the gift. This is no longer necessary with Agrona products!

Maximum oxygen content 100%

Make sure that the first watering has a high oxygen content. This is an absolute necessity for good crop development. Stagnant water mainly degrades the oxygen content. Agrona has the perfect solution for this! The OXYBULL aeration system is placed in the daily supply or clean water silo. It keeps the water fully moving through the micro air bubbles, increasing the oxygen content to 100%. This guarantees you 100% oxygen input for the whole year in any circumstances. Oxygen thus stimulates the growth of beneficial bacteria and improves the quality of the water. The OXYBULL aeration system ensures that the water storage is free of organic dirt and algae. Use the AG STIM in combination with the OXYBULL for optimal results!
