Team
Our team
We are a small team running the Präparatekiste — hands on the product, short lines of communication, a network of farms and researchers, and an active ecosystem around us.
Where we come from
The Präparatekiste has its roots at Hof Eichwerder on the Baltic coast, the Demeter farm of the biodynamic pioneer Wedig von Bonin. Wedig was closely connected with Maria Thun — the founder of the sowing days and co-inventor of barrel compost. The Präparatekiste grew out of this lineage: first as preparation work on the farm, and from 2017 as an independent company.
Eichwerder no longer exists today. What remains is the connection to the people who lived, learned and worked there — and the commitment to keeping biodynamic preparations available in consistent quality.
Who is behind the Präparatekiste
Simon — Managing Director
Grew up at Hof Eichwerder. Took over the Präparatekiste in 2017 and restructured it. Responsible for strategy, product development and the interplay of the three brands. Also a lecturer in strategic innovation and sustainable entrepreneurship. In addition, an active member of the "Wir bauen Zukunft" e.G. cooperative, a place in nature for applied futures research and regenerative principles.
Birte Clausen — Nieklitz warehouse
Goods, shipping, production and product development, an eye on quality in the Werkhalle Nieklitz.
Preparation makers and partner farms
Preparations do not come from a factory. We work closely with Demeter farms that make preparations or advise us on technical matters, including:
Hannah and Thomas Braß — Heilsberger Hof
Both are trained agriculturalists; Hannah is the state representative for biodynamic preparations in Rheinland-Pfalz. Together they run a Demeter family farm in Niederstadtfeld and have been connected with the Präparatekiste for years — as producers, a source of knowledge and sparring partners. → heilsbergerhof.de
Biodynamics under one roof
The Präparatekiste is one of three brands of Rankwerk GmbH:
- Präparatekiste — biodynamic preparations for professionals and hobby biodynamic growers. International shipping.
- Rankwerk — Demeter seeds and tools for the home garden. → rankwerk.de
- Dyyna — international biodynamic learning and tools platform, currently being built. → dyyna.bio
Three brands, three target groups, one shared warehouse and shared know-how.
What we are building right now
Alongside our preparation work, we develop tools for everyday biodynamic farm work — straight from practice and together with the community:
- Planting calendar — digital Moon and constellation calendar, linked with a crop planner, dosage calculator and Demeter documentation.
- Hofbuch — digital farm OS for biodynamic farms: field records, audit documentation and preparation work in one interface. In development; we are proceeding step by step with pilot farms.
Our site: Werkhalle Nieklitz
Our warehouse and workshop are located in the Werkhalle Nieklitz, a site of the Wir bauen Zukunft eG (WbZ) cooperative. Simon is a member of the cooperative, and Rankwerk GmbH is part of the WbZ ecosystem. → wirbauenzukunft.de
We share the hall and grounds with initiatives working in the same direction:
Knirps & Knolle — nursery catering made from regional organic ingredients, founded in 2025, freshly cooked food for nurseries in the region. → knirpsundknolle.de
Hauptsache Tiny — workshop building sustainable, biophilic tiny homes from regionally processed timber. → hauptsachetiny.de
Himmel & Humus — community-supported agriculture right next door, regenerative vegetable growing on the market garden principle. → himmelundhumus.de
TerraSol — regenerative architecture and Earthship building, workshop in the same hall complex. → regenerativearchitektur.de
Institut für regenerative Baukultur (bee-onik) — non-profit institute for regenerative building culture and a resilient lifestyle. Research, teaching and Earthship practice on the WbZ grounds. → bee-onik.de
This neighbourhood is no coincidence. We see our work as part of an ecosystem, not as an isolated company. Farms that supply. Researchers who question. Neighbours who build something different — and tools we use to make it all work together.
