The Effect of Parent Material and Soil Genesis on the Distribution of Selected Major and Trace Elements in Forest Soils of Fuman Masuleh Area Mohsen Nael moh nael@yahoo com 2009 11 11 Department of Soil Science Isfahan University of Technology Isfahan 84156 83111 Iran A Jalalian jalalian@cc iut ac ir H Khademi hkhademi@cc iut ac ir M Kalbasi F Sotohian College Graduate Coordinator F Nourbakhsh Soil Science Department College of Agriculture Isfahan University of Technology Isfahan Iran Environmental Science Department College of Natural Resources Guilan University Guilan Iran Abstract In order to assess the role of geologic and pedologic factors on the total content of major elements as well as the distribution and chemical speciation of selected trace elements in soil residual soils developed on six parent materials including phyllite Ph tonalite To peridotite Pe dolerite Do shale Sh and limestone Li were studied Total content of Si Al Fe Ca Mg K Na Mn Ti P Co Cr Cu Ni Pb V and Zn were compared among different soils and related to the geochemical and mineralogical composition of parent materials Enrichment depletion patterns of trace elements were assessed using Ti as the reference element and lowest horizon as the reference layer A modified sequential extraction procedure was used to fractionate the trace elements into four operationally defined species Notwithstanding the redistribution of all major elements throughout pedons due to soil forming processes the importance of inheritance factor on soil Si Al Mg Fe K and Ti is higher than pedogenic factors MnO content of Pe and Do pedons is governed by geogenic factors while in Sh pedons pedogenic factors especially redox conditions plays the major role The total contents of Co Cr Ni and V are highest in soils derived from peridotite and dolerite Lead and Zn contents are highest in soils derived from shale Lead Zn Cu and Mn have been generally enriched in most pedons except in some acidic and strongly leached soils whereas Co Cr Fe Ni and V have been leached especially from Eutrudepts The latter elements however showed enrichment trend in Hapludalfs and Argiudolls parallel to the development of illuvial B horizons Iron Cr Cu Ni V and Zn are present primarily in the residual fraction independent of soil and parent material type whereas Mn Pb and Co were mainly present in the non residual fractions of most pedons Trace element concentrations in the soils of the study area are related primarily to the parent material type while pedogenic processes appear to have played a minor role Keywords Trace elements Major elements Sequential extraction Pedogenesis Parent material
