Provided is a mixed turf arranged on a soil and including: a synthetic turf, natural grass arranged in the synthetic turf, said synthetic turf including: synthetic filaments suitable to simulate grass blades and a backing consisting of a membrane suitable to support the synthetic filaments, the backing being further as a whole substantially draining, enabling transpiration and permitting the passage therethrough of the roots of said natural grass and which is non-biodegradable.

An artificial turf system (100) provides an existing artificial turf (102) including a plurality of existing artificial turf fibres (104) and an existing artificial turf backing (106) configured to carry the plurality of existing artificial turf fibres, a new artificial turf comprising a plurality of artificial turf fibres and an artificial turf backing layer, where the artificial turf backing layer comprises a carrier structure (302) configured to carry the plurality of artificial turf fibres, and a geogrid (114) positioned between the existing artificial turf and the backing layer of the new artificial turf.

The invention relates to a completely or partially compostable turf (202, 300) the turf being a completely or partially compostable artificial turf or a hybrid turf (202) comprising a completely or partially compostable hybrid turf support, the turf comprising a decomposition inhibitor, the decomposition inhibitor in the turf being adapted to lose its functionality or leave the turf until a defined period of time has elapsed.

A turf surface 80 comprising: (a) a reinforcing root-permeable mat 10; (b) a removable root-permeable backing 60 located beneath the reinforcing root-permeable mat 10; (c) a layer of growth media 42 located on the reinforcing root-permeable mat 10; and (d) natural grass plants 30 having roots 32 extending downwardly through the layer of growth media 42 and the reinforcing root-permeable mat 10 and the removable root-permeable backing 60;
wherein, in use, prior to being laid at a destination site, the removable root-permeable backing 60 is separated from the reinforcing root-permeable mat 10, so that any roots 34 which engage with and extend through the removable root-permeable backing 60 are substantially removed from the turf surface 80.

A turf sports field with a plurality of turf modules (100) having an upper turf surface and peripheral turf edges (5). The turf modules are deployed by means of a remotely operated or autonomously operated lifting and transport vehicle (103), which is provided with a lifting arrangement. When installed, the turf modules (100) are positioned adjacent previously installed turf modules, with a tolerance gap (105) between adjacently positioned turf edges (5) of different turf modules.

An artificial turf system provides an existing artificial turf including a plurality of existing artificial turf fibres and an existing artificial turf backing configured to carry the plurality of existing artificial turf fibres, a new artificial turf comprising a plurality of artificial turf fibres and an artificial turf backing layer, where the artificial turf backing layer comprises a carrier structure configured to carry the plurality of artificial turf fibres, and a geogrid positioned between the existing artificial turf and the backing layer of the new artificial turf.

Hybrid turf (10) comprising a plurality of synthetic fibres (3) made of a biodegradable compound, wherein said biodegradable compound comprises an amount of poly butylene succinate adipate (PBSA) equal to or greater than 60% by weight.

An apparatus for inserting artificial grass strands into the ground may be used, for example, to prepare an artificial grass surface for a sporting field. The apparatus may comprise a frame, a plurality of spools having artificial grass strands wound thereon, a rotary device having a plurality of clamps configured to hold the grass strands, a cutting device configured to cut the artificial grass strands, and an insertion device configured to insert the artificial grass strands into the ground.

A synthetic turf having a mat with a face arranged adjacent to a surface to coat, and a face opposite the face. The turf includes a plurality of blades made of a synthetic material that are connected to the mat. Above the face of the mat, an infill material is provided that is arranged among the blades. The infill material includes a predetermined percentage by volume of a vegetable material consisting of rachis of cereal ear. The infill material also includes a predetermined percentage by volume of a ligninic and/or resinous material of vegetable origin.
