100% Organic Water Storage
With Retentis®, GEFA is ushering in a new era in soil improvement and water management for landscaping, urban greening, and all types of planting projects. Retentis is a 100% organic and fully biodegradable hydrogel, listed by FiBL and certified for organic use, making it ideal for sustainable horticultural practices.
The key function of this innovative absorber is to increase the soil’s water storage capacity, enhance organic matter, and boost overall soil fertility. It also helps improve soil structure and supports the healthy development of plant root systems.
The use of Retentis® not only offers effective protection against drought but also enables the long-term transformation of unproductive, degraded soils into fertile growing areas.
This makes it possible to protect plantings from drought stress—especially in sensitive areas where conventional synthetic hydrogels and water-storing mixtures could not be used due to environmental concerns.
