USDA CALIBRATED SOIL KIT
By Midwest GeoSciences Group

"Help yourself to think on your feet in the field"

Now soil scientists, geologists, and engineers can practice and calibrate the accuracy of their soil texturing skills! The USDA Soil Texture kits consist of eight air-dried soil samples which have been calibrated by passing through particle-size screens and placed in plastic zip-lock bags. Texture ranges from loamy sand to silt loam to clay. Each kit includes a listing of the Texture Class name contained within the kit, as well as sand, silt, and clay. The soil specimens are collected from the Red River Valley near Fargo, North Dakota; near Detroit Lakes, Minnesota; in the Missouri River bottom near Onawa, Iowa, and near Ames, Iowa.
