Substrate intended to serve as a culture support comprising: a first part constituting the backbone of the substrate and representing more than 70% of the total volume of said substrate, composed of particles P with a particle size greater than 100 μm, all of said particles being composed of hard particles P and / or of resilient particles P, said resilient particles constituting a volume proportion PV between 0% and 100% by volume of this first part; a second portion of corpuscular elements P with a particle size of less than 100 μm and constituting from 0 to 450 g / l of said substrate; a third part constituting from 0 to 200 g / l of said substrate, composed of fine fibers having a length of between 3 mm and 100 mm and a diameter of between 5 μm and 35 μm; a fourth part constituting from 0 to 200 g / l of said substrate, composed of other elongate and / or surface inclusions, each of these elongate or surface inclusions having at least one of their dimensions which is much greater than the particle size of the particles of the first part, the sum of the dosage of the third part and the fourth part being greater than 3 g / l of said substrate. Application to the realization of turf sports surfaces and terraces of buildings.
