Calcisols

Calcisols occur in regions with distinct dry seasons, as well as in dry areas where carbonate-rich groundwater comes near the surface.

Characteristics

Soils having a (petro-)calcic horizon (horizon with accumulation of secondary calcium carbonates). In addition, they have no diagnostic horizons other than an ochric or cambic horizon, a calcareous argic horizon, or a gypsic horizon beneath a petrocalcic horizon.
