We produce soils with substantial qualities.

Retentis® is a unique and innovative solution for increasing soil water holding capacity, organic matter, and fertility.

How does Retentis® work?

Everything starts with one idea.

Retentis®, a registered trademark of AgroBiogel GmbH, is a spin-off from the University of Natural Resources and Life Sciences Vienna (BOKU), supported by the EIC - European Innovation Council, the Austria Wirtschaftsservice (AWS), and the Austrian Center of Industrial Biotechnology (ACIB).
