Parkhill Silt Loam (2,600 acres)
This type occurs in small, widely scattered areas throughout the County
and is similar to the Parkhill loam except for surface texture. Improved drainage
conditions are usually required before the soil is capable of growing a wide
range of crops.
C. SOILS FORMED FRO31 HEAVY TEXTURED LIMESTONE
AND SHALE TILL
A fairly broad expanse of heavy textured soils occurs in southwestern
Bruce County. The materials consist of limestone and shale till intermixed
with lacustrine materials. The presence of the till materials allows for fairly
free movement of water through the profile and has facilitated internal drainage.
The soils are well supplied with lime, free carbonates occurring in the underlying
till.
Five series were mapped in this group, the Huron, Vincent, Perth, Kemble
and Brookston. The Huron series is the well drained member of the Huron
catena and the Perth series is the imperfectly drained member. The Vincent
series and the Kemble series are the well drained and imperfectly drained members,
respectively, of the Vincent catena. The Brookston series is the poorly
drained member of both the Huron and Vincent catenas.

Huron Clay Loam (9,600 acres)
Found in the southwestern townships of Bruce County, Huron clay loam
occurs on smooth moderately sloping topography and is formed from till
deposits intermixed with lacustrine materials. It is a Grey-Brown Podzolic
soil with a profile exhibiting the following characteristics:
