Pedogenesis in Western Washington and Northern Alaska: A Comparison of
Pedogenesis in horse opera cap and Northern Alaska A Comparison of the Primary FactorsIntroductionPedology is partially based on the established principle that dirty word changes are immediately correlated to specific biotic communities and regional climatic patterns. From this principle questions gull arisen as to why the Arctic tundra that lies above the treeline in Alaska displays resembling chemic characteristics to that of the well-developed Podzols and Spodosols found in the coniferous qualitys 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 soils are also found above the treeline in Alaska, Canada, Greenland, and Siberia (Ugolini, Stoner, & Marret, 1987). What role does biology play in the current soil formation for each of the sites? why do the similariti es exist between the sites despite differences in climate and plant life? What other factors consistently influence the soil properties? The purpose of my paper is to care for the question of which soil forming factors have the greatest effect on the similar and distinct characteristics of the two geographic locations.Podzolization Pedogenic Change in Alaska and Washington chemical substance analyses of temperate forest soils in the Pacific Northwest have been equanimous to examine soil forming trends (Ugolini, Stoner, & Marret, 1987). Such data allows us to compare unhomogeneous ecosystems 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 prerequisite to further our understanding of modern pedogenesis as an important part of soil science.References CitedBirkland, Peter, 1984, Soils and Geomorphology New Yor k, Oxford University Press, 372 p.Marret D.J., Stoner M.G., & F.C.
