Soils of the Brown Forest Great Group have shallow profiles
and a brownish color in the subsoil.
The Podzol soils have an organic (0) horizon, 1 to 2 inches thick, underlain
by a gray or white Ae horizon, 1 to 2 inches thick. The B horizon is reddish brown
and contains concentrations or sesquioxides or organic matter or both and is
usually divisible on the basis of color difference into two sub-horizons. Most of
the Podzols in the county have an additional B horizon containing an accumulation
of clay as well as sesquioxides. This B horizon occurs at depths of 24 to 36 inches
and is similar to the B horizon of the Grey-Brown Podzolic soils.
Many of the soils of Dufferin County have developed under poorly drained
conditions and therefore are classified in Dark Grey Gleysolic and Organic Great
Groups.
The Dark Grey Gleysolic soils have a very dark gray Ah horizon generally 7
to 8 inches thick and high in organic matter. The Ah horizon is underlain by a dark
