Water loss through evaporation is one of the biggest challenges in land rehabilitation and revegetation.
Independent trials conducted by an accredited third party have now confirmed that EnviroMatrix ECM hydromulch significantly reduces evaporation and improves soil moisture retention – delivering measurable benefits for plant establishment and long-term soil health.
Methodology – how the trial was conducted
The study was designed to accurately measure the effectiveness of EnviroMatrix ECM hydromulch in reducing evaporation compared to untreated soil. Controlled test beds were established, with identical soil conditions to ensure fair comparisons. Evaporation rates, depth of moisture loss and cumulative water loss were key indicators used to assess performance.
Throughout the trial, daily monitoring of water loss showed a consistent reduction in evaporation where EnviroMatrix ECM hydromulch was applied. The hydromulch layer acted as a barrier, reducing direct exposure to the sun and wind, slowing moisture loss and maintaining optimal growing conditions.
Key findings on data-backed performance
- Up to 35% reduction in accumulated water loss compared to untreated soil.
- Daily evaporation rates lowered by up to 1.5mm/day, preserving vital moisture.
- Shallower depth of evaporation, ensuring moisture stays available for plant roots longer.
- Improved soil structure that retains water more effectively over time.
These results confirm that EnviroMatrix ECM hydromulch improves soil moisture availability, creating a stable and favourable environment for seed germination and root development.
Why this matters for commercial revegetation
By reducing evaporation, EnviroMatrix ECM hydromulch helps retain critical moisture in the soil – supporting stronger plant establishment and improving long-term vegetation success. These findings highlight its value in arid and drought-prone environments, where water conservation is essential for sustainable land rehabilitation.
Furthermore, with moisture retained for longer, plants experience less water stress, leading to improved survival rates and faster early-stage growth. This not only enhances the effectiveness of revegetation projects, but also reduces the need for supplementary watering – lowering costs and resource use.
