Great Groups of the Vertisolic Order

Two Great Groups of the Vertisolic Order occur in Saskatchewan. Both have B and/or C horizons with evidence of mixing (Bv or Cv) and polished surfaces along fracture planes (Bss or Css).

Humic Vertisol Soils

These soils occur in the moister, central part of the agricultural region and have a darker A horizon than the Vertisol Great Group.

Vertisol Soils

Soils of the Vertisol Great Group have an A horizon that is difficult to distinguish from the underlying B or C horizon. They occur in the drier variants of the heavy clay landscapes in Saskatchewan.
