Excerpt from The Color of Soils The color of soils has long occupied the attention of both geologists and agriculturists and has considerable importance theoretically and practically. Theoretically the color is of importance as a guide to the origin and processes involved in the formation of the soil and as an indication of the relative age of any particular soil. It is of practical importance because it determines to a greater or less extent the absorption of the sun's energy, and is often a guide to the drainage conditions, to the crop adaptations, and to the cultural methods best suited to the soil.

Thus the material by which soils ordinarily considered red are colored is ferric ox1de, which itself is never a pure red, for it varies from dark brown to yellowish, and when in the soil it is further tinted and Shaded by other materials. When applied to soils the color descriptions used in this bulletin mean the tints and shades which for the sake of Simplicity are termed red, yellow, brown black, or Simple combinations of these.
