How Soil Morphologiy Reflects Landscape History

Soil profiles serve as natural archives, reserving records of patt environmental conditions and landscape evolution. The vertical arangement of soil horizons - the organic- rich O horizons, the topsoil A horizons, thee leached E horizons, the subsoil B horizonon, and the unaltered C horizons - captures the cumulative effects of climate, vestication, and geomorphic processes over threands of years.

For instance, a thick, dark A horizonof ten indicates sustaged grasland ecosystems with high organic matter input, whereas a prominent E horizonbeneath forested areas supmensts intenses leaching dousin by abundant rainfall.
