<p>An artificial grass turf carpet (10) comprises a ground structure (11) having an upper surface and upstanding synthetic grass fibres (12) attached to said ground structure, which synthetic grass fibres form a grass surface of said artificial grass turf. The carpet further has upstanding synthetic base layer fibres (15) attached to said ground structure at positions between the upstanding synthetic grass fibres. The base layer fibres have a lower height than said grass fibres.The said base layer fibres are positioned tight against one another and against neighbouring grass fibres, so that a dense base layer (16) is obtained aboye which the grass fibres extent. An artificial grass turf system includes such a carpet and has preferably a thin, rubber-free infill layer (20) on top of the base layer.</p>
