Global Soil Change Workshop 2009 visited the Calhoun Experimental Forest to evaluate human forcings of the Critical Zone, long-term soil experiments, anthro- and traditional pedology, biogeochemistry, land-use history, and land management.
The origin and functions of the horizontal redoximorphic tiger stripes in Calhoun's B horizons is a topic Ryan Fimmen took into the literature and the subject of future biogeochemical studies. Here, to emphasize a point Markewitz uses a 25-lb piece of granitic gneiss to describe his bedrock-inheritance hypothesis of the origin of the baffling tiger stripes found a depth in many Calhoun profiles.
The origin and functions of the horizontal redoximorphic tiger stripes in Calhoun's B horizons is a topic Ryan Fimmen took into the literature (Biogeochemistry 2008) and the subject of on-going biogeochemical study and discussion. Here, Markewitz uses a 25-lb piece of granitic gneiss to describe his alternative bedrock-inheritance hypothesis of the origin of the baffling tiger stripes found a depth in many Calhoun profiles.
