As part of its partnership with Astredhor Seine-Manche, ECT visited the horticultural research station at Saint-Germain-en-Laye. The experiment under way analyses various plots that have been vegetated using topsoil and fertile substrates produced by ECT. The protocol looks at the development of perennials and turf. Three types of fertile substrate are under test: Marl-chalk, silt-clay and sand-silt.
This visit was an opportunity to take stock: The first results on the various types of fertile substrate seem quite conclusive.
