Traditional cultivation of cultivated plants takes place in the exhibition field. The rare species of arable flora are specifically promoted and preserved here.

With its valuable and rare landscape types, Brentjong is one of the most important cultural landscapes in the Pfyn-Finges Nature Park. The dry and permeable soils are suitable for growing winter rye as well as Valais rye. The latter also leaves space for a diverse range of accompanying arable flora. In this exhibit garden you can discover biodiversity and tradition.
