Color of soils is mainly due to (1) organic matter
content and (2) presence and chemical form of Fe and Mn.
- 1. Both of these properties are important in the
identification of hydric soils.
- 2. Common names for colors (e.g., light red, grayish
brown) mean different things to different people. Soil
scientists describe color using Munsell Soil Color Charts
- The Munsell color system embodies three aspects of color
-- hue, value, and chroma.
