Solonetzic soils

Brown Solonetz (B.SZ)

Common horizon sequence: Ah, Bn or Bnt, Csk

Soils of this subgroup have a solonetzic B horizon as defined for the Solonetzic order and the properties specified for the Solonetz great group. They are associated with grass and forb vegetation and a subarid to semiarid climate. Areas of these soils often have patchy microrelief caused by differential erosion. The B horizon is exposed in some eroded pits. Plant growth in the eroded pits is usually very sparse.

Brown Solonetzs have either an Ah, Ahe, or Ap horizon with color values higher than 4.5 dry and chromas usually higher than 1.5 dry, or an exposed solonetzic B horizon. They have neither a strongly alkaline (pH of 8.5 or more) A horizon nor faint to distinct mottles that indicate gleying within the upper 50 cm.
