Soil Survey of McHenry County, Illinois Part I - Soil Data Mart

26 Soil Survey of
792A—Bowes silt loam, 0 to 2 percent
slopes
Setting
Landform: Outwash plains and stream terraces
Position on the landform: Summits
Slope range: 0 to 2 percent
A typical soil series description with range in
characteristics is included, in alphabetical order, in this
section. Additional information specific to this map
unit, such as horizon depth and textures, is available
in the “Soil Properties” section in Part II of this
publication.
Composition
Bowes and similar soils: 85 percent
Dissimilar soils: 15 percent
Similar soils:
• soils that have a lighter colored surface layer
• soils that have a darker subsurface layer
• soils that contain sandy and gravelly deposits at a
depth of less than 40 inches or more than 60 inches
• soils that contain more sand in the upper and
middle parts of the subsoil
Dissimilar soils:
• the poorly drained Dunham soils in depressions and
drainageways
• the somewhat poorly drained Grundelein and
Millstream soils in the lower positions on the landform
