Abstract
A cover for covering cultures so as to improve soil conditions and plant growth includes a first, top layer of biological material such as straw, bark, peat, wood shavings, etc., a lower layer of UV-degradable synthetic material sewn to the first layer to thereby establish stitch holes which are water permeable, and another perforated layer of synthetic material e.g. a fleece is welded or bonded to said lowest layer, such that its perforations do not optically align with the stitch holes, but water can flow in between the two synthetic layers.
