“Organic Brussels sprouts require patience and precision — that’s exactly how we grow them.”

Organic brussels sprouts
The Netherlands
Hi, I’m Frank Bos of Maatschap Bos Bio. Together with my father and our team, I run an 80-hectare, 100% organic arable farm in Dronten, in the Netherlands. Since 2014, I have been actively involved in the business and restarted the cultivation of organic Brussels sprouts for Nature & More.
Organic sprout cultivation as a specialty
We have been growing organic Brussels sprouts for several years now. Sprouts are a demanding crop, especially in organic farming, as they are sensitive to insects and fungal pressure and remain in the field for a long period. This makes careful planning, monitoring and prevention essential. Despite these challenges, Brussels sprouts have recently been rediscovered as a healthy, flavourful and versatile vegetable, and we are proud to contribute to their renewed popularity.

Preventive organic farming
Organic sprout cultivation is all about prevention. Our approach focuses on healthy soil, good soil structure, balanced fertilisation, resilient plant material and well-considered crop rotation. Variety choice also plays an important role, as some varieties are naturally more resistant than others. By planting different varieties from April to May, we ensure a continuous supply of sprouts from September through February.
Innovation in the field
To support healthy crops without chemicals, we experiment with innovative mechanical techniques. One example is weeding with compressed air, which helps remove cabbage root fly eggs and reduces disease pressure without harming the soil or plants. Mechanical weed control and light machinery further help maintain soil structure and biodiversity.

A family business with continuity
Bos Bio works with a stable, close-knit team that has grown into an extended family over the years. Organic farming for us is not just a production method, but a long-term commitment to land stewardship. With a new, modern storage and packing facility, renewable energy from solar panels and compostable packaging, we continue to invest in a future-proof organic sprout operation.
Bos Bio uses solar panels to supply renewable energy to the farm.
Cooling systems operate with environmentally friendly refrigerants.
Compostable nets are used for packaging Brussels sprouts, reducing environmental impact.
Crops are irrigated mechanically using surface water from local ditches.
Irrigation is applied both day and night to ensure consistent water availability during the growing season.
Water use is monitored and regulated according to regional water authority guidelines.
At Bos Bio, organic Brussels sprouts are grown on the basis of prevention: healthy soil, balanced fertilisation, crop rotation and careful soil cultivation.
Sprouts and potatoes are rotated, with each crop returning to the same field only once every five years to maintain soil vitality.
Light machinery is used to protect soil structure and soil life during cultivation and harvest.
Bos Bio actively works with variety selection to reduce vulnerability to insects and diseases.
Field margins and green manure crops are used to support natural enemies such as ladybirds, predatory mites and parasitic wasps.
Continuous monitoring and preventive measures maintain natural balance without chemical inputs.
Organic production ensures that employees are not exposed to synthetic pesticides or fertilisers.
Frank Bos continuously tests and develops new techniques, such as compressed-air weeding, to improve working conditions and crop resilience.
Bos Bio works with a stable, long-term team of employees who are closely involved in the daily operation of the farm.
The company operates with respect for its surroundings and local environment in the agricultural region of Dronten.
Bos Bio is an 80-hectare, 100% organic family farm run by Frank Bos and his father, with succession secured for the future.
Brussels sprouts are harvested, cooled, sorted and packed on-site, keeping the supply chain short and transparent.
A modern storage and sorting facility was purpose-built to meet organic standards and optimise logistics.
