摘要: Publisher Summary This chapter discusses the soil biogeochemical cycling of inorganic nutrients and metals. Soil microorganisms have a profound effect on transformations involved in large number cycles other than carbon (C) nitrogen (N), such as macronutrients phosphorus (P) sulfur (S), various micronutrients environmental pollutants. A conceptual model for generic nutrient or metal element illustrates continuous flow energy, water, nutrients, materials across ecosystem's boundaries. Meteorologic transfers consist windblown particulate matter, dissolved substances precipitation, gases. Geologic fluxes include soluble matter transported by surface subsurface water mass movement mineral during events erosion, landslides, lava flows. focuses phosphorus, sulfur, trace Environmental significance P, S, biogeochemistry is described along with unifiers elemental soil.
