<p>The present invention relates to seed carriers, preferably in the form of seed-containing sheets to be laid out on the ground. Earlier the production of such seed carriers has involved high cost because the production could not be run continuously on a large scale. According to the present invention it is possible to produce such seed carriers continuously on a large scale owing to the utilization of forming wire machines for the production. This is enabled by the fact that the seed carrier is formed in part of a peat material which is fibre graded, in that colloids and small particles have been removed, and/or of a peat material having a degree of humification of 1 to 3 according to von Post's scale*, and in part of a fibre material interconnecting said peat fibres. The seed carrier according to the invention may be used in growing all kinds of crop, preferably in growing plants in dry districts, for instance desert areas, where it will form a cover which promotes the retention of moisture in the underlying soil. * von Post's scale is described in a Ground Planning Report: "Torv i Sverige, 1977:1", a planning report elaborated by "N?mnden f?r Energiproduktion:s planeringsgrupp f?r torv".</p> |
