50 <strong>Soil</strong> <strong>Survey</strong> <strong>of</strong><br />
Composition<br />
Elliott and similar soils: 85 percent<br />
Dissimilar soils: 15 percent<br />
Similar soils:<br />
• soils that have a seasonal high water table at a<br />
depth <strong>of</strong> more than 2.5 feet<br />
• soils that have no subsurface layers<br />
• soils that contain more sand in the upper part <strong>of</strong> the<br />
pr<strong>of</strong>ile<br />
Dissimilar soils:<br />
• the poorly drained Ashkum and very poorly drained<br />
Peotone soils in drainageways and depressions<br />

146B—Elliott silt loam, 2 to 4 percent<br />
slopes<br />
Setting<br />
Landform: Moraines and till plains<br />
Position on the landform: Summits, backslopes, and<br />
footslopes<br />
Slope range: 2 to 4 percent<br />
A typical soil series description with range in<br />
characteristics is included, in alphabetical order, in this<br />

unit, such as horizon depth and textures, is available<br />
