Now soil scientists, geologists and engineers can practice and calibrate the accuracy of their soil texturing skills. This USDA Soil Texture Kit will help you better identify and communicate what type of soil you are analyzing. When Paul (one of our Product Pros) saw this Kit, he knew our customers would love it. Get your hands “dirty” and improve your soil identification! The eight air-dried soil samples have been passed through 1/4" wire screen and placed in plastic zip-lock bags. Texture ranges from loamy sand to silt loam to clay. 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.
