Claim 6:
7. A method of producing a biodegradable nonwoven textile comprising seeds using a nonwoven textile machine, the nonwoven textile machine comprising a cross-lapping portion and a seed distributing machine unit, positioned in the cross-lapping portion of the nonwoven textile machine which is able to distribute seeds over at least a part of an incoming width of a veil of biodegradable fibres during cross-lapping of the veil of biodegradable fibres, wherein the seed distributing machine unit comprises at least one receptacle for seeds having a dispensing opening for regulated outlet of seeds onto a veil of biodegradable fibres, the seed distributing unit is movable in a horizontal plane in a direction transverse the movement of the veil of biodegradable fibres, and the nonwoven textile machine comprises a needle punching portion situated after the cross-lapping, seen in the direction of the biodegradable nonwoven textile production line of the machine, the method comprising producing a veil of biodegradable fibres, distributing seeds over at least a part of an incoming width of the veil of biodegradable fibres during cross-lapping of the veil of biodegradable fibres and then needle-punching the veil of biodegradable fibres into a biodegradable nonwoven textile comprising seeds, whereby the distributing of seeds is performed over a central portion of the incoming width of the veil of biodegradable fibres and the cross-lapping is run in a suitable speed in order to provide a cross-lapped veil of biodegradable fibres where the central portion of the incoming width having seeds is embedded between a previous tail portion of the incoming width, underneath, and a following head portion of the incoming width, above.
