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

44 Soil Survey of
Composition
Dresden and similar soils: 85 percent
Dissimilar soils: 15 percent
Similar soils:
• soils that have a lighter colored surface layer
• soils that have a thicker surface layer
• soils that contain less sand and more silt in the
upper one-half of the profile
• soils that contain sandy and gravelly deposits at a
depth of more than 40 inches or less than 24 inches
• soils that contain loamy till in the lower part of the
profile
Dissimilar soils:
• the somewhat poorly drained Kane soils in the
lower positions on the landform
• the poorly drained Will soils in depressions and
drainageways
