A Granby Sandy Loam Profile
ALLISTON SERIES
The Alliston soils are imperfectly drained soils associated with the Tioga soils
and commonly occupy the more level parts of the sandy outwash plain near the
Pine River.
The profile of the Alliston soils is similar to that of the Tioga soils but is
mottled in the upper part. The profile has a thin black Ah horizon underlain by a
light gray Ae horizon. The Ae horizon rests on a yellowish brown, mottled Bhf
horizon which becomes lighter in color with depth and is underlain by another
slightly darker, mottled Bt horizon at a depth of about 30 inches which contains
more clay than the layers above or below it. Pale brown, calcareous sand parent
material occurs at a depth of about 32 inches.
Although the Alliston soils have an agricultural potential in Dufferin County
they are presently under trees.
GRANBY SERIES
The Granby soils are the poorly drained associates of the Fox and Tioga soils
but they also occur in depressional areas in association with soils developed on
glacial till. The Granby soils have developed from calcareous outwash sand. Since
they occur in depressions, the soils are saturated with water for the greater part
of the year.
The soil profile is typically Dark Grey Gleysolic. In the uncultivated state an
8-inch surface horizon high in organic matter is always present. Under cultivation
this dark surface soil becomes mixed with the underlying horizon, resulting in a
