About us

The essence of Retentis®

Retentis® revolutionizes modern agriculture with the following three functions:

Protection of plants
against drought

Our 100% wood-based hydrogel absorbs and stores water when it rains or during irrigation and slowly releases it to the plants during dry periods.

Saves irrigation water and associated costs

Retentis® reduces irrigation by up to 40%

Enhancing Conversion in fertile soils

Retentis increases soil organic matter and traps important macro- and micronutrients. Thus, it converts agriculture none productive soils into productive soils including sand and degraded soils

Multiple unique benefits

Humus formation: Retentis® mimics humus and gradually degrades into humus thereby improving soil structure, organic matter, soil fertility and plant nutrient supply.

Water retention: Improves soil water holding capacity, supports plant growth during dry periods.

Long-term impact: Minimum 3-5 years of sustainable support for plant growth and soil quality.

Environmentally friendly: Suitable for conventional and organic farming, protects against drought, and improves infertile soils.
