5.2 Local and regional pedodiversity
The same study area can be used to illustrate the phenomenon of
profoundly different implications with respect to pedodiversity and soil
variability at regional and local scales.
While the regional inventory of mapped soil taxa compared to parent
material variability does not suggest divergent evolution, detailed local-
scale analyses may turn up multiple soils on a single parent material.
For example, Fig. 3.4 shows soil and weathering profi les temporarily
revealed by excavation in Madison County, Kentucky in 2010. At least fi ve
morphologically distinct soils are evident over a 5 m distance ...
