The mulch mat is composed of a plurality of layers of biological and synthetic material, the successive layered materials being connected to one another, preferably by means of a quilting seam. The uppermost layer is of biological material and the bottom-most layer is of synthetic material, and after the quilting a further synthetic layer is additionally glued or welded to the layer of synthetic material. The mat can also consist of a plurality of such layers. The welded-on or glued-on covering layer consists of opaque, but moisture-permeable material or of opaque material which is prepared for moisture permeability by being appropriately equipped with holes of very small diameter or with slits. These slits or holes of very small diameter are to be made outside the region of the quilting seams.</p> |
