 In fertile soil, it produces a high grass yield, and in Britain and Ireland, it is frequently sown for short-term ley grassland, often with red or white clover ("Trifolium").In Britain, it is also used as an indicator of nonspecies-rich grassland, as it outcompetes the rarer plants and grasses, especially in fertile soils.Agri-environment schemes such as the Countryside Stewardship Scheme, Environmentally Sensitive Areas Scheme, and Environmental Stewardship give funding to species-rich grasslands that do not have an abundance of ryegrass.
