example 8

fine-loamy, mixed, superactive Pachic Argicryoll

Calcium carbonate in the subsoil is derived from the lime-rich parent material. These minerals dissolve in the upper profile where the moisture content is greater, leach downward, and precipitate in the lower profile where there is less soil moisture. Clay translocation in the upper profile often begins following the downward movement of carbonates in the soil. In this soil, clay translocation is evidenced by the formation of the Bt horizon.

Wavy horizon boundaries can be seen on the right side of the profile. These are the result of extensive animal burrowing, possibly badger in this case.
