Austria / Achensee – Soil restoration

Left: A fairway in spring before using Terrawell® products; visible soil damage, including from winter use as a cross-country ski track (and resulting factors like wax residues, track machines, etc.)

Middle: The same fairway a little later after a single Terrawell® Classic application.

Right: An almost fully recovered and regenerated fairway after two applications of Terrawell® Classic.

Austria / Achensee – Putting green restoration
Golfplatz Achensee

The soil samples above were taken under the same climatic conditions in exactly the same spot:

Before: Clearly visible waterlogging due to black layer formation and barely noticeable root growth.

After: Thanks to soil treatment with Terrawell® products: complete dissolution of the black layer and a clearly visible, dense root system.

Germany / Munich – Reducing replantings

Damaged pines in Munich sprouted again after applying Terrawell® Classic.

Terrawell® products were also used successfully when planting new trees in downtown Munich – reducing plant loss from 7–10% the previous year to just 1.5%. Natural efficiency meets soil health.

Switzerland / Crans Montana – Alpine soil restoration for ski slopes

At 1,350 m elevation, microbial biomass developed impressively within just one year through applying a mixture of organic material and Terrawell® Classic. Over this period, biomass rose from 272 µgC/g with a ratio of 34% fungi and 66% bacteria to 1612 µgC/g, with fungi increasing to 79% and bacteria decreasing to 21% at a depth of 10 cm.

France / Brittany – New life for peach trees

In the picturesque orchards of Brittany, our work helped young trees affected by peach rot to recover. Just three months after application, these trees stand as a symbol of nature’s resilience and the transformative power of Terrawell® Classic.

Switzerland / St. Gallen – The maize experiment

Four maize plants were potted at the same time, under the same climatic conditions, in identical containers – but the substrate in each pot could not be more different.

Even visually it’s clear: Terrawell® Classic combined with the appropriate fertilizer guarantees the ideal basis for growth and plant well-being.

Germany / Karlsfeld – Goodbye algae in standing water

In a self-initiated trial, SE-Bau Landschaftsbau GmbH treated its own pond with Terrawell® Classic. As a result of the introduced microorganisms, after around 30 (!!) days there were hardly any algae left, but a clearly improved water quality that allows a clear view to the bottom of the pond. All natural, without chemicals.

KENYA / Mombasa – From scarcity to abundance.

Despite challenging conditions, the sandy and saline soils of Mombasa were revitalized with a mixture of organic material and Terrawell® Classic.

The result? Extensive, lush areas of vetiver and kikuyu grass transforming once-barren land into blooming meadows. A local archbishop summed it up well: our work is like “breathing life into dry bones.” These words capture the essence of our mission.
