History/background
This unit has long been called "Modern Soil," and it seems undesirable to replace it with a geographic name.
Type section
Type location

Stratigraphic relationships
In a stratigraphic sequence it is overlain only by man-made deposits.
Extent and thickness
The soil ranges from very shallow to many feet in depth and is developed in any sediment that may underlie the present surface.
Lithology
The term Modern Soil is applied to any soil profile genetically related to the modern topographic surface.
The Modern Soil is the soil described in the many county soil reports of the University of Illinois Agricultural Experiment Station and of the U. S. Department of Agriculture Soil Conservation Service.
