Soil morphology focuses on standardizing descriptions of soil properties and features in the field. Although often qualitative and empirical, these descriptions aid in the interpretation of soil properties measured in the laboratory through chemical, biological and physical methods.

The formative elements are used in the names of suborders and lower taxonomic levels. Table courtesy of R. Weil. Many other formative elements can specify unique soil properties at each taxonomic level. Each formative element has a connotation for a given soil. These connotations of the formative elements used for suborders and great groups are lis...
Table adapted from King et al. (2003). A complete taxonomic name communicates a great deal of information about the soil if we understand each part of the name. As an example of the quantitative information revealed in a taxonomic name, the following classification name will be dissected by category. Consider, for example, the Harney soil, with a t...
Now that you have studied the characteristics of the 12 soil orders, enter the most appropriate soil order name in each rectangle.
To illustrate the structure of Soil Taxonomy, separate a complete taxonomic name into the six categories. Follow the example of the Harney silt loam in figure 4.2.
As a further exercise in understanding taxonomic names, complete the following questions. Use the list of taxonomic names of soils representative of Mollisols from the prairie pothole region of Iowa below to answer these questions. The Des Moines lobe of the Wisconsin glaciation covered north-central Iowa with a deep layer of glacial deposits, and ...
Table courtesy of C. J. Moorberg. Notice that the wetter the drainage class (that is, the shallower the depth to the seasonal high water table), the higher the “aqu” formative element becomes in the overall classification. That is because Soil Taxonomyprioritizes soil management considerations. The depth to the seasonal high water table would be a ...
State soils have been selected for all 50 states and three territories in the U.S. The group of soils represents a diverse sample of soil conditions and classifications. It serves as an interesting focus for a little practice at deciphering and understanding Soil Taxonomy. Use the attached list of state soils in Table 4.7 along with Table 4.2, Tabl...
As an introduction to soil reports, look through a typical printed county soil survey report; take note of the manual’s organization and the extensive content. The report begins with some background information on the county, along with an overview of how the survey was conducted. The county soil conditions are described, and the soil mapping units...

Soil morphology is the branch of soil science dedicated to the technical description of soil, [1] particularly physical properties including texture, color, structure, and consistence. Morphological evaluations of soil are typically performed in the field on a soil profile containing multiple horizons .
Jul 29, 2015 · This article introduces many important soil concepts including development, classification, properties (physical, chemical, and biological), quality, and conservation. A general understanding of soil concepts and these interwoven relationships is essential to making sound land management decisions.

Jan 1, 2024 · Many soil animals, which are mostly invertebrates and often referred to as “fauna,” regulate nutrient cycling at ecosystem and global scales by feeding directly on plant materials and other organic substrates. The fragmentation or comminution of these materials enhances their decomposition.
