  • Patent number: 4283880
    Abstract: A peat paper used to improve the quality of the soil in connection with planting, sowing or weed-control. The paper consists of peat fibres (4), cellulose fibres (1), and a bonding agent. The disclosure also teaches the method of producing said peat paper. The peat paper is characterized in that in a lower layer the cellulose fibres (1) support the peat fibres (4) and in that the cellulose fibres and peat fibres (1,4) are bonded together by means of the bonding agent in a dry-formation process so as to form paper-like sheets or webs. The resulting peat paper is soft and owing to its method of production controlled amounts and/or layers of additives, such as fertilizers, seeds, hormones, and similar additives may be incorporated into the paper.
