A fertilisation experiment was started in the French Alps on an acid grassland at 2000 m in 1989 where lime as calcium carbonate ("liming") and Thomas Slag enriched by potassium chloride ("fertilisation") were added in a random block design until 1992. Since then, no further amendments were applied.
