10. loamy-skeletal,
mixed, superactive, mesic Lithic Argixeroll
(Gwin series)
This soil formed in loess mixed with basalt
colluvium. The Bt horizons contain 27 to 35%
clay. This is due to a long period of soil
formation on a stable land surface. The percentage of coarse fragments
in these soils is generally greater than 35%. The
high percentage of coarse fragments and the
shallowness of the soil, limit the total
available water holding capacity to around 1.5-3
inches.
