pedogenic การใช้

• Canadian soil scientists required a new method of soil classification that focused on pedogenic processes in cool climatic environments.
• Bioturbation was initially recognized as a pedogenic force by Charles Darwin, and remains a key term of the pedogenic lexicon.

• Further study revealed that these submersed sediments underwent other soil forming ( pedogenic ) processes including additions, losses, and transformations of energy and matter.
• The Ua samples come from pedogenic carbonate coatings on pillars and only indicate the time after the site was abandoned the " terminus ante quem ".
• It is a general term ( not to be confused with duripan ) for a zone of chemical sedimentary bodies through pedogenic and ( or ) non-pedogenic processes.
• It is a general term ( not to be confused with duripan ) for a zone of chemical sedimentary bodies through pedogenic and ( or ) non-pedogenic processes.
• Groundwater silcretes typically formed in more localised, topographically lower settings such as valley bottoms and slopes, whereas pedogenic silcrete tended to form extensive sheets over very large areas.
• Tabor, N . J . and I . P . Monta馿z, 2002 : Shifts in late Paleozoic atmospheric circulation over western equatorial Pangaea : Insights from pedogenic mineral W18O compositions.
• Underclays typically show considerable evidence of having been altered by plant activity and illuviated clay pore fillings, different types of pedogenic microfabrics, rhizocretions, caliche nodules, root molds, and soil horizons.
• Catenas are found to be a great location for the study of soil science, given that the catena concept focuses on past history of the land surface, on hydrology, erosion, sediment transport, and pedogenic processes.
• This occurred at deeper levels, at the intersection with the groundwater table ( forming " groundwater silcrete " ), or close to the surface, within the soil profile ( forming " pedogenic silcrete " ).
• Wilkinson and Humphreys offer evidence that  bioturbation appears to be the most active pedogenic process operating in many soils .  While probably close to the mark, research over multiple decades strongly indicates that bioturbation is the dominant process in the upper part of most soils, notable exceptions possibly being vertisols and cryosols, where shrink-swell and freeze-thaw processes, respectively, appear dominant.
