are not used to any extent, but tests made elsewhere indicate 
that this soil will respond with profit to the use of phosphate 
fertilizers. 
SUPERIOR FINE SANDY LOAM. 
The surface soil of this type to a depth of from eight to ten 
inches consists of a loose friable loam, or fine sandy loam of a 
dark brown color. It usually becomes somewhat lighter in color 
and coarser in texture to a depth of from twelve to twenty 
inches where the heavy red clay characteristic to this series is 
found. This heavy subsoil frequently contains thin seams of 
fine and very fine sand, and in places it is also common to find 
a very small amount of limestone fragments through it. The 
depth of the heavy subsoil is somewhat variable ranging from 
eight to twenty-four inches. 
This soil is of limited extent, and most of the areas, all of 
which are small, are scattered through the towns of Center, 
Freedom, Kaukauna, Greenville and Grand Chute. 
The surface of this soil is level, with only a very few undula¬ 
tions. The natural drainage is somewhat deficient because of 
the heavy subsoil, but is somewhat better than the drainage of 
the heavier types of this series. Tile drains could be profitably 
installed over a considerable proportion of this type, however. 
The original timber growth consisted largely of maple birch, 
with a small amount of elm, some hemlock, and pine. 
The greater part of this soil has been cleared, and placed 
under cultivation, and the farm crops common to the region 
are being grown successfully upon it. Because of its limited 
extent, there are but few, if any, farms located entirely upon 
this soil. 
In the improvement of Superior fine sandy loam, drainage is 
a factor which must be considered in many cases, but in some 
instances tile drains are not necessary. 
The supplying of additional organic matter should be con¬ 
sidered, however, and the plowing under of a legume crop wil 
greatly assist in this direction.*
