“…Together the three changes in the model of soil emphasize the fundamental importance of anthropedology as an applied and basic science. Human impacts on soil are well studied in archeology, geoarchaeology, anthropology, and environmental science (Eidt, 1977;Butzer, 1982;Davidson, 1982;Short et al,, 1986;Johnson and Lindberg, 1992;Alexandrovskaya and Alexandrovskiy, 2000;Hiller, 2000;Holliday, 2004;Howard and Olszewska, 2011), A major challenge for contemporary soil scientists is to grow an anthropedology that extends pedology's inherent interdisciplinarity (Cline, 1961;Dobrovolskii, 2006) and that precisely and accurately quantifies human interactions with soils and the ecosystems they support, Cline (1961) anticipated mueh about these ongoing changes. Well aware ofthe rising human influenee on soils, Cline stated that intensifying land management ",,, magnifies man and his activities as factors of soil formation and demands recognition of his work," About the soil as solum, Cline suggested that researeh with the lower boundary of soil, may force us "to extend the lower limit of our model of soil to greater depth,,,", clearly anticipating the deepening ofthe genetic model of soil and even the concept of Earth s Critical Zone (NRC, 2001 ;Brantley et al, 2006;Wilding and Lin, 2006), Human-soil relations, soil's lower boundary, and soil polygenesis have wide application for humanity and are critical to the development of soil seience in the 21st century, a time that is placing unprecedented demands on the Earth's soil economically and environmentally.…”
