Plinthite: Severely eroded road bank (Dothan soil)
Because of the sandy and loamy surface and subsurface layers, Dothan soils are highly erosive. In this image, the soil is severely altered, eroded to the depth of the underlying, dense and compact aquitard or "brick" layer. Because of the dense compact nature, this layer us much less erosive. It not only slows or restricts water move, it limits root penetration.
