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 confirmed for fine-grained percentages using a hydrometer. Each sample is stored in a plastic zip-lock bag along with a sample ID with the USDA Textural Name and the precise grain size percentages. Texture ranges from loamy sand to silt loam to clay. Each kit includes a quiz sheet and an answer sheet listing of the Texture Class name contained within the kit, as well as sand, silt, and clay fraction percentage.

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.
