CLIC RECYCLE Presents CLIC TERRA to Bernard Magrez

Our Approach to Protecting Vineyard Soils 

Bordeaux, 20–22 October 2026

"The soil is the first heritage of a great wine."

This was the starting point of CLIC RECYCLE's presentation to Bernard Magrez in Bordeaux, where the company introduced CLIC TERRA, its patented biodegradable mulch developed for agricultural applications, with a particular focus on vineyards.

As climate change intensifies heat and water stress, protecting vineyard soils is becoming increasingly important. Exposed soil can reach temperatures higher than the surrounding air, contributing to water loss, erosion and stress on the vines. These conditions can affect both grape production and quality, while conventional approaches may involve compromises between soil protection, weed management and environmental impact.

CLIC TERRA: Turning waste into a resource for vineyards

CLIC TERRA offers an alternative: a natural, biodegradable mulch made from recovered hair from hair salons and plant fibres. This patented nonwoven material is designed to protect the soil, retain moisture and regulate temperature, while avoiding the use of conventional plastic mulch and herbicides.

The solution is also designed to support more efficient water management. Trials conducted by the University of Almería have shown irrigation water savings of up to 30%.

For vineyards, these properties offer a practical approach to addressing some of the challenges associated with increasingly hot and dry growing seasons.

Evidence from a Bordeaux vineyard

The results shown are from a non-irrigated vineyard in Bordeaux, monitored between June and October 2026 over 118 days.

During heatwave days, when air temperatures exceeded 35°C, the average maximum soil temperature at a depth of 10 cm reached 38.5°C in uncovered soil. Under CLIC TERRA, it was 29.4°C — a difference of approximately 9°C.

These results show that, through a Cesens station and connected application, a system enables real-time field measurements and traceability at vineyard and parcel level, and highlights the potential of CLIC TERRA to help protect vineyard soils under conditions of intense heat, opening possibilities for more informed vineyard management.

Because wine is passed from one generation to the next, and the soil deserves the same care.
