Our Innovative approach

More than ever, it is necessary to conciliate, as best as possible, human activity and environment respect. We carried out for several years an all-inclusive revegetation activity that tries hard to respect this necessary compromise.

Valorhiz is specialist in soil and brings innovative and specific rhizospheric biotechnology to your projects. By now, we

use a biologic engineering that has been fully tried and tested on a high diversity of soils - including tailings from mines or quarries – under various climates.

The innovative services provided by our company are intended as well for mines or quarries as for road embankments, landfill sites, green spaces, industrial wastelands, ….

Your all-inclusive revegetation project

Based on accurate site diagnosis, our solutions take action on both soil health and plants biodiversity and allows the establishment of a sustainable vegetation cover.

We behave as a quality partner in your project (adaptability depending on site constraints, reporting, supply communication 

deliverables…) and we enhance local companies (nurseries, landscape business, …) that we carefully select and manage.

In this way, we handle different project types: revegetation, rehabilitation, ecologic corridor, melliferous flower field, biodiversity management, multifunctional hedges…



Our Biotechnological solutions

Microorganisms in the rhizosphere play major roles in natural ecosystems (mineral fertility increase, water stress decrease, tolerance of limestone and heavy metals). Valorhiz developed efficient microbial solutions (isolation, characterization, production) we enhance in our project. The understanding of soil functions (in situ diagnosis, laboratory 

analysis) together with the supplying of ecological-adapted and optimized plants (seed and seedling under controlled inoculation) allows us to achieve revegetation goal on infertile soils, without watering and fertilization. This global and natural approach guarantees an optimal plant place setting and preserves site ecosystem (local biodiversity).
