Harkaway Silt Loam— Stony Phase (43,700 acres)
Most Harkaway silt loam is more stony than that described above and it
has been mapped as a stony phase. The profile is similar to that of the less
stony silt loam but there are many more stones throughout the profile.
The presence of surface stone and the large quantity of stone in the profile
make clearing a tedious process. However, much of the land has been cleared
and is under cultivation. The use of the soil is conditioned by the amount of
stones on the surface. Where the stones have been removed the soil is used for
the same agricultural endeavours as the Harkaway silt loam described above.
Cleared areas where the stones have not been removed are used for pasture
and grazing land.
Harkaway Loam (1,700 acres)
This soil occurs in the neighbourhood of Tara. The profile of this type
resembles that of the Harkaway silt loam but the surface horizons have a loam
texture. The land use and soil management is similar to that of the Harkaway
silt loam.
Harkaway Loam— Stony Phase (3,800 acres)
The stony phase of the Harkaway loam has similar profile characteristics
to the Harkaway loam except, for a larger number of stones. Although stoniness
makes this land difficult to clear, most of it is cultivated and crops are grown
amongst the stone piles. This soil has the same management problems as the
stony phase of the Harkaway silt loam.
(ii) Imperfect Drainage
Listowel Loam (16,900 acres)
The Listowel loam is the imperfectly drained member of the Harriston
catena, and the Harriston and Listowel soils generally occur in close association
forming an intimate land pattern. The horizons in the Listowel are not as
The use of the stony phase of the Harkaway series is conditioned by
the number of stones on the surface
