Welcome to AgroBiogel
AgroBiogel stands for future-oriented solutions in agriculture, horticulture, and forestry. With RETENTIS®—an innovative water and nutrient storage granulate made from lignin, a by-product of the pulp industry—we enable resource-efficient cultivation and sustainable soil management. Our technology helps to use water and nutrients more efficiently, counteracts the effects of climate change, and ensures the long-term health of our soils.
How RETENTIS® works


Experience the RETENTIS® effect
Turn the knob and see the difference.
On day 0, two identical basil plants start: on the left in soil with 2% RETENTIS®, on the right in conventional soil.
After 21 days without a drop of water, the result is clear:
The RETENTIS® plant remains lush green and vital, while the untreated plant dries out.
💧 RETENTIS® stores water and nutrients directly in the root zone, reliably protects against drought stress, and reduces your watering effort. See for yourself - get RETENTIS® now.
