Soil Color Charts
Many color listings for easy soil identification
Now you can make soil classification simple. This guide follows the guidelines of the U.S. Soil Conservation Service for color classification of soils. Can be used for soil samples, rocks, archaeological specimens, animal pelage and other natural products. Matte color chips are mounted on 13 tabbed charts: 10R, 7.5R, 5R, 2.5YR, 5YR, 7.5YR, 10YR, 2.5Y, 5Y, and 10Y-5GY, plus a two-page gley chart (blue and green colors, and gray scale for submerged soils) and a white page. White page describes carbonate, silica, gypsum and soluble salts and shows half steps from 8.5 to 9.5 in value with chromas of 1 and 2 for N, 7.5YR, 10YR and 2.5Y. Charts store in a loose-leaf binder on water-resistant pages that allow dirt and debris to be easily wiped away. Charts measure 41/4"Wx71/4"H. USA made.
