Soil creation is a result of carrying out successions. Succession is the process in which land that is inhabitable by organisms is reclaimed and made fertile. This is done using pioneer species, which do not require soil to grow. After a while, these species are removed and a secondary succession is carried out. After this process, soil is created and the land becomes fertile.
