The book is organized to make it faster and easier for you to identify and communicate the color of soil in the field. Soil Composition and Color Soil color and other properties including texture, structure, and consistence are used to distinguish and identify soil horizons (layers) and to group soils according to the soil classification system called Soil Taxonomy. E-unit: Understanding Soil Color Page 3 AgEdLibrary.com A classification for engineering purposes should be based mainly on mechanical properties, e.g. The Geotechnical Gauge is a field data chart for field engineering work. Soil Color Classification Charts Book The book is organized to make it faster and easier for you to identify and communicate the color of soil in the field. Easiest Way is to use the Use USCS chart Step 1: Classify Soil A: use the USCS Flow chart to find classification: Since 51% passing #200 sieve that is > 50 Fine-grained soil LL is 35 which is < 50 follow the top row of chart no organic odor or color follow the inorganic In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), chroma (color intensity), and value ().It was created by Professor Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system for soil research in the 1930s. Compare. Music by: Purple Planet-Transmission 2. Soil classificationis the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. Soil color is an important soil property used in soil description and classification. Soil color indicates the makeup of the soil within a given geographic area, which can influence the land's fitness for use, such as wetlands, optimum crops to plant, viability for waste water systems and other uses.

Therefore, these earlier logs and past descriptions must not be changed to conform to current standards. Several classification systems exist: 1. But soils have many different colours and there is no good or bad, just some hints as to how much organic matter may be in your soil. Soil classification is the grouping of soils with similar engineering properties into a category by using the results of laboratory-based index tests, e.g., group name and symbol (ASTM D 2487, AASHTO M 145). Soil color and other properties including texture, structure, and consistence are used to distinguish and identify soil horizons (layers) and to group soils according to the soil classification system called Soil Taxonomy.
