Résumé :	Restoration of sites degraded by industry to species-rich semi-natural vegetation communities is difficult; it usually involves the addition of soil ameliorants but excessive fertility may favour dominance by competitive species. In a field-experiment we tested the establishment of a biodiverse mesotrophic grassland community using different compost types (comprising of mixtures of waste materials), application rates and seeding (with species in the target community). Compost addition to the alkaline sandy substrate increased soil organic matter, nutrient content and water holding capacity (WHC), whilst decreasing pH. Over the first two growing seasons compost addition, (especially at a higher rate) increased total vegetation cover (from
