Are Technosols developing on former settling pond comparable to natural soils?

Pedogenesis of soils developing on human-made substrates is of interest because of the increase of soil anthropisation. Little knowledge is available on these technosols and a better understanding of their evolution is needed and of the fate of the potentially polluting materials they contain. Parent material origin may strongly influence their formation and functioning and the governing processes have to be elucidated. They may be specific or similar to those occurring in natural soils. Our objective is the investigation of a technosol developing on a former settling pond of the steel industry
