Clic Recycle presents CLIC TERRA to Bernard Magrez

Our approach to protecting vineyard soils

Bordeaux, 20–22 October 2026

«Soil is the first heritage of a great wine».

This was the idea that opened Clic Recycle's presentation to Bernard Magrez in Bordeaux, where the company presented CLIC TERRA, its patented biodegradable mulch developed for agricultural applications, with a special focus on vineyards.

As climate change intensifies heat and water stress, protecting vineyard soils is increasingly important. Bare soils can reach higher temperatures than the surrounding air, contributing to water loss, erosion and vine stress. These conditions can affect both grape yield and quality, while conventional methods can involve trade-offs 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 keratin recovered from hair salons and plant fibres. This patented nonwoven material is designed to protect the soil, retain moisture and regulate temperature, while avoiding conventional plastic mulches and herbicides.

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

For vineyards, these properties offer a practical way to tackle some of the challenges of increasingly hot and dry growing seasons.

Evidence from a Bordeaux vineyard

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

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

These results show that, with a Cesens station and a connected app, the system enables real-time field measurements and traceability at vineyard and plot level. They also highlight CLIC TERRA's potential to help protect vineyard soils in intense heat, opening new possibilities for better-informed vineyard management.

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