Retentis® – 100% Biological Water Retainer

Retentis® – 100% Biological Water Retainer

With Retentis®, GEFA heralds a new era in soil improvement and water management in landscaping and all types of plantings. Retentis is a 100% biological and fully degradable hydrogel - FiBL listed and bio-certified. The essential function of this innovative absorber is to increase the water-holding capacity of the soil, improve organic matter, and enhance soil fertility. The application of Retentis® not only offers effective drought protection but also enables the sustainable transformation of unproductive soils into fertile arable land. Thus, plantings that previously could not benefit from synthetic hydrogels and water-retaining mixtures can now be protected from drought stress.

Due to its biological composition, Retentis® is particularly environmentally friendly and thus represents a forward-looking alternative for gardening and landscaping. The hydrogel, made 100% from lignin (wood), stores water during rainy periods or scheduled watering sessions and releases it continuously to the plants during dry periods. This innovative approach not only leads to effective water retention in the soil but also supports moisture retention and thereby stress-free plant development.

Simultaneously, Retentis® can transform infertile soils, including sandy substrates, into fertile arable land. Active in the soil for at least 3-5 years, the granulate then decomposes into humus – a crucial step in increasing organic matter in the soil and thereby laying the foundation for long-term healthy plant growth.

Advantages of Retentis®

The first durable and biological hydrogel made from 100% wood:Retentis® relies on an entirely natural composition that is not only effective but also environmentally friendly.

Active for at least 3-5 years, depending on soil type:Retentis® offers long-lasting effects, ensuring sustainable soil improvement over several growing seasons.

Increases the soil’s water-holding capacity:The hydrogel maximizes the soil’s water storage capacity, which is particularly crucial during dry periods.

Decomposition into humus, enhancing soil fertility:The transition of Retentis® to humus not only boosts soil fertility but also promotes the formation of a sustainable ecosystem in the soil.

Transforms infertile soils, including sand, into fertile land:By converting sandy soils into fertile arable land, Retentis® opens up new possibilities for agriculture and gardening.

Absorption of fertilizers/nutrients, storage, and slow release to plants:Retentis® acts as an efficient carrier of fertilizers and nutrients, which are then slowly released to the plants, ensuring sustainable nutrient supply.

Reduces costs for water, fertilizers, irrigation, and labor:Retentis can be used alone or in combination with any form of irrigation, reducing water consumption and minimizing energy and labor efforts. Retentis helps save up to 40% water by reducing the frequency of irrigation.

Approved without restrictions for conventional and organic farming:Retentis® is a versatile solution that can be used for all plantings as well as in both conventional and organic farming.

Overall, Retentis® represents a groundbreaking solution for the sustainable management of soils and opens up new perspectives for urban plantings in gardening and landscaping, including compliance with ecological standards.
