Abstract: The invention relates to a method for the construction and sustainable management of a hybrid turf sports ground, with management of a shallow water table in the structure of the sports ground, which comprises: a first step of constructing a structure (S) placed on a base (F), the structure comprising N stacked porous layers (Ci); a second step of installing turf on the surface of the top layer (Ci), the installation of the turf possibly being carried out by sowing; and, of the N layers, one hybrid layer (H) is constituted either (i) by a cultivation substrate that comprises synthetic reinforcing elements, or (ii) by a cultivation substrate that shares the space of the hybrid layer (H) with synthetic reinforcing elements.

Abstract: A local coordinate system in which the turfed area is digitized, and a marking area is divided into elementary cells to form a matrix, and the pattern to be marked is broken down into a mosaic of pixels associated with the elementary cells of the matrix. Next, for each elementary cell of the matrix, tasks to be performed by the marking devices are determined according to a value of the pixel associated with said elementary cell, to mark the pattern to be marked on the marking area; and the movement of the vehicle over the turfed area is controlled so as to cover all of the elementary cells, and the marking devices are controlled so as to perform the tasks to be performed in each elementary cell.

Abstract: A culture support substrate comprising: a first part, making up the backbone of the substrate and representing more than 70% of the total volume of the substrate, composed of particles P>100 ?m with particle size greater than 100 ?m, the particles as a whole consisting of hard particles PH>100 and/or of resilient particles PR>100, wherein the resilient particles make up a proportion by volume PV of between 0% and 100% by volume of this first part; a second part of corpuscular components P<100 with a particle size of less than 100 ?m, and making up from 0 to 450 g/l of the substrate; a third part, making up from 0 to 200 g/l of the substrate, composed of fine fibers between 3 mm and 100 mm in length and between 5 ?m and 35 ?m in diameter; and a fourth part, making up from 0 to 200 g/l of the substrate.

Abstract: A wood heat-treating method, a plant for carrying out the method, and the heat-treated wood. The heat-treating method consists in bringing each wood piece of a treatable lot into contact with a temperature controlled conductive press, whose temperature is accurately controllable in time and in intensity. The pieces are heated to or held at a desired temperature by any heat control for treatment and the wood is conductively heated to maintain the temperature and to cool the wood.
