How RETENTIS® works

Icon water drop – symbolizes water storage and efficient irrigation with Retentis

Reduces water demand by up to 40 %

RETENTIS® stores up to 10 l of water per kg of granules and reduces watering requirements by up to 40 %

Icon plant sprout in the soil – stands for healthy plant growth through improved soil structure

Protects plants from drought stress

The 100 % natural granules store water and release it evenly to the plants during dry periods.

Icon Earth with trees – stands for climate adaptation, resilience and a greener future

Significantly improves soil structure

RETENTIS® improves soil structure, degrades down into humus and increases nutrient retention.

Icon factory with plant – symbolizes bio-based innovations for the circular economy

Promotes the circular economy

Lignin becomes 100% organic RETENTIS® and returns carbon to the soil.

Before After

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.
