  1. On Russian concepts of soil memory –expansion of Dokuchaev's pedological paradigm Alexander Tsatskin Zinman Institute of Archaeology University of Haifa, Israel

  2. This talk presents a review of book Victor O. Targulian and Sergei V. Goryachkin (eds) Soil Memory: Soil as a Memory of Biosphere-Geosphere-Anthroposphere Interactions 2008 (in Russian, with Foreword by V.O.Targulian, S.V.Goryachkin and Concluding Remarks by V.O.Targulian, S.V.Goryachkin, N.A.Karavaeva in English)

  3. Soil Memory Book contents I. General approaches toSoil memory – 11 authors II. Mineral carriers of soil memory – 14 authors III. Biological carriers of soil memory – 3 authors IV. Anthropogenic soil memory – 10 authors

  4. Anthropic Albic Luvisol in the Russian plain Model of soil evolution since the late Glacial through the Holocene photo by Victor Targulian

  5. Significance of Evolutionary Pedology Dan Richter and Dan Yaalon (2012) “The Changing Model of Soil” Revisited Henry Lin (2011) Three Principles of Soil Change and Pedogenesis in Time and Space Paleopedology commission of the IUSS and SSS Division of the EGU both invest efforts to promote studies on soil polygenesis, surface soils records and archives

  6. Input of energy & matter Complex soil biotic-abiotic system Outcomes of composition, structure & information Model of soil formation

  7. Soil functioning and self-organization

  8. Soil reaching a steady state Reversible orsteady state (?) profiles horizons aggregates Increasing structure & system complexity with time T I M E

  9. Residual solid phase micro-results SMR Fluctuating processes of soil functioning – formation of SMR Accumulation of SMR within soil system Specific pedogenic processes SPP Records of solid phase carriers

  10. After Lin (2011), note random processes

  11. A A A A A A B1 B1 B B B2 B2 Types of soil development-no-additional deposition Transgressive Regressive Climate & biota impact Climate & biota impact time solum thickening solum reducing

  12. Soil memory Capability of a soil system to store and record in its stable properties the information about conditions (factors) and processes of formation and development, evolution and degradation

  13. Sedimentary system: book-like record 4 green 3 brown 2 yellow 1 green sedimentation time

  14. O A A A E AC Bm C Bt BC C C C Soil system: palimpsest record Albic Luvisol: texture-contrast soil of southern taiga Nearly zero sedimentation Time zero

  15. Conclusions Soil Memory concept develops Dokuchaev’s paradigm Via (a) Theoretical principles of soil memory as ability of soils to store variable over time environment forcing

  16. (b) New Scientific Evidence on Russian soil records - Holocene soil records related to European vegetation periods - Radiocarbon dating of Holocene soils; - Clay minerals, Fe minerals and carbonate nodules as earlier records - Waterlogged soils in a historic perspective - Phytoliths, soil organic matter and microbiota - Anthropic changes in agricultural soils

  17. Soil memory concept – The RUSSIAN CONCEPT - challenges earlier idea that soil is a mirror of landscape; Focus is put on duality of soil as “super” complex biotic-abiotic system whose formation includes both self-organization (soil functions) and evolution (a palimpsest record)

  18. Are Soil memory - Soil polygenesis - Soil archives – Soil records all synonyms? YES – and NO

  19. What’s a really important message? That soils may be records of earlier land history HAS TO BE demonstrated in every specific case – Soil Memory IS LIKELY AN INHERENT PROPERTY of soil Anyway, it is a useful idea to be kept in mind even when dealing with hazardous substances in anthropic soils. Use it – you may be surprised for good… Thanks!
