CHAPTER Y. 
GROUP OF POORLY DRAINED SOILS. 
POYGAN CLAY LOAM. 
This type is of very small extent. Small areas are found near 
the center and southeastern parts of the county, the largest of 
these occurring north of Stephensville in Ellington Township. 
It is closely associated with the Superior clay loam and silt 
loam, and occupies depressions and low, gently sloping areas 
bordering streams. 
The surface soil of the Poygan clay loam to a depth of from 
eight to fifteen inches is a dark brown to black, sticky compact 
clay loam, rich in organic matter. The subsoil becomes lighter 
in color for a few inches before grading into pinkish-red clay at 
from fifteen to twenty inches. This clay is very compact and 
tenacious and extends to an undetermined depth. 
In topography the Poygan clay loam is flat to gently sloping. 
The surface is low which coupled with the impervious character 
of the subsoil makes the natural drainage very poor. 
Less than half of this type is under cultivation. The greater 
part of it is badly in need of drainage, and in its present con¬ 
dition is valuable only as pasture and for the marsh hay which 
may be cut. Where the type has been properly drained, it has 
a high agricultural value. It is especially adapted to hay and 
small grains, while corn and other crops common to the region 
do well. It is rather heavy for potatoes, but cabbage and sugar 
beets are grown with fair success. 
POYGAN SILT LOAM. 
No areas of Poygan silt loam of any great extent are found, 
although small patches of the type occur scattered throughout 
practically every township in the county. It is closely associ-
