The advantages of RETENTIS®

💧 Increasing the water retention capacity of the soil:
RETENTIS® maximizes the soil's water retention capacity, which is particularly important during dry periods.

🌳 Protects trees and plants from drought stress:
RETENTIS® forms a water reservoir in the soil, protecting plants from water shortages and drought.

🍂 Decomposition into humus, which increases soil fertility:
The decomposition of RETENTIS® into humus not only promotes soil fertility but also the formation of a sustainable ecosystem in the soil.

⏳ Active for at least 3–5 years, depending on soil type:
RETENTIS® offers long-lasting effects and thus ensures sustainable soil improvement over several growing seasons.

🌱 Absorption of fertilizers and nutrients, storage and slow release to the plants:
RETENTIS® acts as an efficient carrier of fertilizers and nutrients, which are then slowly released to the plants to ensure a sustainable supply.

🚫💦 Preventing rapid leaching of fertilizers:
RETENTIS® also serves as a storage medium for fertilizers. This prevents rapid leaching of fertilizers, thus contributing to efficient and sustainable fertilizer use.

💰 Reduction of water, fertilizer, irrigation and labor costs:
RETENTIS® can be used alone or in combination with any form of irrigation, reducing water consumption and energy and labor requirements. RETENTIS® helps save up to 40% water by reducing the frequency of irrigation.

✔️ Approved for conventional and organic farming without restrictions:
RETENTIS® is a versatile solution that can be used in both conventional and organic farming.

🔄 Circular economy through innovative lignin use:
The production of RETENTIS® from a by-product of the pulp industry not only contributes to soil improvement, but also makes a significant contribution to the circular economy and shows how upcycling a previously underutilized side stream can have a positive impact on the environment.

RETENTIS® in action

The RETENTIS® particles attach themselves to the roots and function like tiny sponges. They absorb water and nutrients and release them exactly where the plant needs them most: directly at the roots.
This ensures that plants remain optimally supplied even during long dry periods.
