The Munsell color system is based on the human visual system's perception of color, and color is all around us, everywhere we look, at any moment. This convenient classification system has been used in the United States for more than 55 years, aiding in the management and stewardship of natural resources. Illustrations of soil grain structures, charts for estimating proportions of mottles and coarse fragments, color name diagrams, and instructions are furnished. The book is set up to make soil color evaluations in the field quickly and easily. Dull colours: yellows, and greys, often found together in mottled horizons indicate that the soil is not well drained and does suffer from prolonged saturation. Brown, yellowish, or reddish colors are mainly the result of precipitated iron (essentially rust) that coats soil particles. Learn more. These terms include sand (s), loamy sand (ls), sandy loam (sl), sandy clay loam (scl), loam (l), clay loam (cl), silt loam (sil), silty clay loam (sicl), silty clay (sic), and clay (c). The book is organized to make it faster and easier for you to identify and communicate the color of soil in the field. Dark brown or black color in soil indicates that the soil has a high organic matter content. The subsoil, where clay accumulates, blocky and prismatic structure develops,and colors are variable is called the B horizon. *To request a soil test kit, contact Sarah Strausbaugh ( [email protected] ). One of the main advantages of a soil evaluation over a percolation test (a traditional method of testing septic field areas) is that layers within the soil that severely limit the function of septic systems can be defined. Just as paint stores have pages of color chips, soil scientists use a book of color chips that follow the Munsell System of Color Notation (www.munsell.com). The Munsell system provides a standardized reference for determining soil hue, intensity and darkness. Color is strongly influenced by humus and iron compounds. These charts consist of color chips that have been assigned names based on their hue, value, and chroma. Examples include Bt (clay accumulation in the B horizon), Bg (gray colors in the B horizon indicating poor internal drainage), and Ab (an A horizon that has been covered by fill or alluvial sediment).

Installation of curtain drains, importation of fill material, or use of alternative sewage disposal systems are options that can be used where limiting layers occur at shallow depths. Surface soils are placed in one of five color classes: Very dark—approximately 5 percent organic matter Color and color patterns provide indications of mineral and organic content, as well as moisture levels, in soils. Peat and muck soils very high in organic matter are usually very poorly drained. Aspect is the direction that the measured slope is facing as one looks downhill. Very poorly drained soils generally lie in enclosed depressions and are frequently ponded. The Ph (acidity level) of your soil has a lot to do with how well your plants grow. Color subjectivity. The biggest problem with accuracy in these kinds of pH tests, however, is the subjectivity that comes along with color matching, and how humans perceive color in different ways. Each comparator has a removable film color chart and color coded top. Four to seven horizons are commonly present within the top 60 inches of a soil profile. A soil scientist indicating the colors of the soil layers from a core sample to determine the best uses for the land. These limiting layers include bedrock, the seasonal high water table, dense soils with slow permeability, and sandy or gravelly soil with very rapid permeability. Classes of consistence include very friable (vfr), friable (fr), firm (fi), very firm (vfi), and extremely firm (xfi). 1 Laminated Color Chart for comparison with your test results It is also necessary to have a small amount of tap water and a small sample of the soil that you are going to test.
