    Game Changer in Soil Science. The Anthropocene in soil science and pedology.
    (Journal of Plant Nutrition and Soil Science, 2020-02-01) Richter, DD
    © 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The venerable science of pedology, initiated in the 19th century as the study of the natural factors of soil formation, is adapting to the demands of the Anthropocene, the geologic time during which planet Earth and its soils are transitioning from natural to human-natural systems. With vast areas of soils intensively managed, the future of pedology lies with a renewed science that can be called anthropedology that builds on the pedology of the past but proceeds from “human as outsider” to “human as insider.” In other words, the human in pedology must shift from being a soil-disturbing to soil-forming agent. Pedology is well prepared to respond to the challenges of the Anthropocene, given the decades of research on human-soil relations throughout human history and throughout the period of the Great Acceleration (Steffen et al., [76]). However, quantitative understanding of soil responses to the diversity of human forcings remains elementary and needs remedy.

    The changing model of soil revisited
    (Soil Science Society of America Journal, 2012-06-14) De Richter, DB; Yaalon, DH
    In 1961, the late Marlin G. Cline wrote a remarkable essay entitled, "The Changing Model of Soil" for the 25th Anniversary Issue of the Soil Science Society of America Proceedings. Cline was most impressed with how geomorphology was enriching pedology, and with the increasingly sophisticated views of soil time and of the processes of soil formation. We revisit Cline's general objectives by re-evaluating the changing model of soil from the perspective of the early 21st century, and by taking stock of the application of soil models to contemporary needs and challenges. Today, three ongoing changes in the genetic model of soil have far-reaching consequences for the future of soil science: (i) that soil is being transformed globally from natural to human-natural body, (ii) that the lower boundary of soil is much deeper than the solum historically confi ned to O to B horizons, and (iii) that most soils are a kind of pedogenic paleosol, archival products of soil-forming processes that have ranged widely over the life of most soils. Together and each in their own way, these three changes in the model of soil impact directly human-soil relations and give structure and guidance to the science of anthropedology. In other words, human forcings represent a global wave of soil polygenesis altering fluxes of matter and energy and transforming the thermodynamics of soils as potentially very deep systems. Anthropedogenesis needs much better quantifi cation to evaluate the future of soil and the wider environment. © Soil Science Society of America.
