Pedogenesis in Western Washington and Northern Alaska: A Comparison of

Pedogenesis in Western Washington and Northern Alaska A comparison of the Primary FactorsIntroductionPedology is partially based on the established dogma that alter changes are directly correlated to specific biotic communities and regional climatic patterns. From this principle questions have arisen as to why the Arctic tundra that lies to a higher place the treeline in Alaska displays similar chemical characteristics to that of the well-developed Podzols and Spodosols found in the evergreen forests of Washington. The Podzols and Spodsols of these coniferous forests are defined by their cool and humid regional climates and by the acidic parent material from which they formed. Recent studies indicate that the E and Bs horizons that define the temperate forest turds are also found preceding(prenominal) the treeline in Alaska, Canada, Greenland, and Siberia (Ugolini, Stoner, & Marret, 1987). What role does biota play in the current soil formation for each of the sites? Why do t he similarities exist between the sites disdain differences in climate and vegetation? What other factors consistently influence the soil properties? The purpose of my paper is to address the question of which soil forming factors have the sterling(prenominal) effect on the similar and distinct characteristics of the two geographic locations.Podzolization Pedogenic depart in Alaska and Washington Chemical analyses of temperate forest soils in the peaceable Northwest have been collected to examine soil forming trends (Ugolini, Stoner, & Marret, 1987). Such info allows us to compare various eco governing bodys and their characteristic pedological processes. Ugolini et al 1987 show how the soil solution analysis allows us to see . . . a simple two-compartment system (p.91). The first ... ...d processes, principles, and knowledge necessary to further our understanding of modern pedogenesis as an important part of soil science.References CitedBirkland, Peter, 1984, Soils and Geomorp hology New York, Oxford University Press, 372 p.Marret D.J., Stoner M.G., & F.C.
