THERE’S NO WILDLIFE WITHOUT QUALITY SOIL
An ever greater presence of wildlife is one of the guiding principles in La Confluence. But this is only possible if the soil contains sufficient nutrients to allow plants and trees to flourish. In Le Champ, where industrial activity has made the soil sterile, a new system has been set up called “Terre fertile 2.0". This ecological and sustainable solution for revitalising soil promotes short distribution circuits and preserves the local agricultural soil that is often collected and transported elsewhere. The aim is to reduce greenhouse gas emissions and negative impacts on the landscape.
Le Champ, fertile soil for experimentation
“TERRE FERTILE 2.0” (FERTILE SOIL 2.0)
The principle of “Terre fertile 2.0” is simple. It consists in making topsoil from work site soil (excavated material), silt, plant waste and compost. This simple recipe is used on a large scale in La Confluence. The system also uses earthworms, which feed on organic matter which they recycle by digesting it. The soil is enriched with nutriments which the worms constantly distribute throughout the soil as they travel. The galleries they dig improve soil permeability and aeration. Water and air penetrate more easily into churned soil. Later on, the planted vegetation will help maintain the soil’s fertility. The method is both natural and effective!
