   In respect of properties of the fine fraction, lithosols may be pedalfers or pedocals, but their morphology is dominated by rock, stones or concretionary material. Regosols, immature soils on sands, are included in this group for convenience.

   These are called the pedocals and pedalfers. Pedalfers are humid-climate soils where leaching is dominant. The al and the fer in the pedalfer refer to the concentrations of aluminum and iron (ferum) that are found in the zone of illuviation.
