Rule-seed mixture
The standard seed mixture in Germany is a guideline for the mixing ratio of seeds in horticulture and landscaping. These blends are often considered the standard.
DIN 18 917 adopts the requirements of the guideline.
Requirements
The definitions of the standard seed mixtures (RSM) are established in Germany by the rules of the Forschungsgesellschaft Landschaftsentwicklung und Landschaftsbau e. V. (FLL). The various RSM standards can be found in the current FLL publications. The overview of the FLL rule seed mix offers a spectrum of 410 varieties of 10 species . The German ryegrass ( Lolium perenne ) is represented most diverse with 135 varieties.

Standard seed mixtures for sports facilities
In sports field construction, the construction method according to DIN 18035 has become widely accepted. The recommendation of RSM 3.1 applies as a guideline for the production of turf as well as for the classic sowing of sports fields. According to the FLL, the RSM 3.1 sports turf mixture consists of 40% German ryegrass ( Lolium perenne , in two varieties) and 60% meadow bluegrass ( Poa pratensis , in three varieties). The use of pure seeds (i.e. only one variety) is strongly discouraged due to the risk of failure.
The football or sports turf in Central Europe essentially consists of mixtures that are mainly based on two components: German ryegrass ( Lolium perenne ) and meadow panicle ( Poa pratensis ). This applies to the production of turf as well as to the recommended seed mixtures.
Individual circumstances can be taken into account within the tolerance of RSM 3.1. So you can put together a suitable mixture within the RSM 3.1 from the municipal football field to the stadium lawn for professional sport. For special purposes, in addition to the varieties mentioned, the reed fescue ( Festuca arundinacea ) with its tolerance to moisture and the lager bluegrass ( Poa supina ) with its high tolerance to shade are possible.
The mixture for a golf course according to RSM 4 is made with subspecies of the red ostrich ( Agrostis capillaris ), the white ostrich ( Agrostis stolonifera ) and the common red fescue ( Festuca rubra ) - as well as Poa pratensis and Lolium perenne in the area of the tees and fairways. Depending on the location in sun or shadow areas or on the greens , variations come into their own.
