SOIL SUBVEY OF OUTAGAMIE COUNTY. 
CHAPTER III. 
GROUP OP LOAMS AND FINE SANDY LOAMS. 
SUPERIOR LOAM. 
Extent and distribution. —The Superior loam occupies a total 
area of approximately one township. It is found most exten¬ 
sively in the northern half of T 24 N, R 19 E in the towns of 
Seymour, Osborn, Freedom. 
Description. —The surface soil of this type to a depth of about 
ten inches consists of a dark brown friable loam which contains 
a moderate amount of organic matter. This type is also free 
from stones and contains but very little gravel. The subsoil 
below ten inches grades abruptly into the heavy compact red 
clay which is characteristic of this series. This bed of clay 
extends to an undetermined depth, probably forty to fifty feet 
at least. 
Topography and drainage. —The surface of this type, as is 
characteristic of this series, is level or only very gently undulat¬ 
ing, and because of the level surface and heavy subsoil the nat¬ 
ural drainage is somewhat deficient. These are associated with 
this soil a large number of areas of soils belonging to the Poygan 
series which occupy poorly drained depressions. 
A large part of the Superior loam would be benefited by tile 
drainage, although up to the present time, but few tile drains 
have been installed. 
Present agricultural development *—Most of this soil has been 
cleared and placed under cultivation, and is now in highly im¬ 
proved farms. About the only exception to this of any note is 
in the northern part of T 24 N, R 19 E where a portion of this 
soil was included in the Indian Reservation. Practically all of 
the general farm crops common to this region are grown upon 
this type. It is a good general farming soil, especially adapted 
to small grains and grasses. The dairy industry has been de¬ 
veloped to a considerable extent upon it.
