  1. Restore/create species-rich, semi-natural grassland

    A 1985 review of four techniques aimed at reducing soil fertility for the restoration of semi-natural grassland or heath (Marrs 1985) found that there was some success. Addition of inorganic nitrogen to a crop was found to extract more phosphorus and other elements from the soil than treatments with no fertilizer addition. Fertilizer addition almost completely exhausted the soil phosphorus store in long-term wheat experiments. Three studies investigating nutrient removal by stubble burning were reviewed (Allen 1964, Kenworthy 1964, Chapman 1967). Burning decreases phosphorus availability and increases potassium availability. Topsoil stripping reduces fertility, but can result in the loss of a large proportion of the seed bank.
