The invention relates to a ground with natural grass, particularly, but not exclusively, a sports pitch, mainly intended to be set up in tropical regions or regions of low rainfall. The ground is made up of a trough 1 whose bottom 1 and sides 3 are covered with a waterproof sheet, of base drainage 5 arranged from the bottom 2 of the trough, of a layer of sand or expanded hard materials 9 filling the trough, on which the layer of grass 10 is planted, and of a water supply evenly distributed over the area of the ground, arranged in the layer of sand 9 between the bottom 2 of the trough and the layer of natural grass 10. This water supply, which forms a sub-irrigation network, consists of a large number of dripping pipes 11, arranged parallel to the drains 5. <IMAGE>
