Soil Science has traditionally been an umbrella for soil physics, soil chemistry, soil microbiology, soil fertility, soil morphology, and soil technology. The area dealing with soils as entities in and of themselves has commonly been referred to as pedology (Arnold, 1983). Pedological activities in the United States have been prominent in the ...

A basic understanding of soil science, especially pedology (soil morphology and pedogenesis) and soil chemistry, is essential for making meaningful interpretations of archeological context and site-formation processes that account for the contemporary archeological record. This record, as expressed in surficial, buried, and stratified cultural deposits, is an imperfect and biased record of ...
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 .
meaning of the word or phrase. For soil science students and soil survey practitioners who want more than a simple definition, this glossary offers additional information for a deeper understanding. A wide array of terms are included. Some are terms from Soil Taxonomy that have specific technical definitions and criteria. Examples include

Soil forms part of the pedosphere (on the Earth’s crust). The main branches of soil science as indicated above are edaphology and pedology. Both divisions address soil physics, chemistry, and biology. The pedosphere experiences numerous contacts with the atmosphere, biosphere, and hydrosphere. The interactions make soil science a very integrated an...
Soil classification is the arrangement of soil into different classes regarding similarity in characteristics and behavior. For example, to classify soil in terms of mechanical properties, permeability, strength, and stiffness will be measured. The primary features of soil will take into consideration the size and shape of soil structure, grains, a...
The process of forming soil is known as pedogenesis. The initial composition of soil begins from the “parent material” (rocks) which is either below or above the ground level. Several climatic conditions play essential roles in the rate and formation of soil. The rocks wear out over time if blown away by wind or transported by flowing water or glac...
Soil morphology is a branch of soil science that describes the physical (observational) attributes of soil and its type on the soil horizons using internationally recognized means. In the past, the soil was described as heavy or light, sandy, saline, dry or moist, marshy, soft or compact, stony or sedimentary. Description of soil and its properties...
Soil science has played a significant role in the agricultural development sector, especially in Sub-Saharan Africa. The study of soil has managed to provide for human needs such as food production, which solely depends on the soil. The ultimate goal of studying soil science is to provide knowledge and sufficient information on soil formation and m...
Soil morphology is all that can be seen and felt about a soil. It includes not only “what is there” but also how it is “put together” – its architecture. To many, the main components of soil morphology include horizonation , texture, color, redoximorphic features, porosity, structure , and consistence , i.e., the look and feel of the soil.

Jul 29, 2015 · Pedologists (scientists who study the origin and composition of soils as a component of natural systems) continue to learn more about soil morphology, chemistry, mineralogy, and biota, thus tighter limits on groupings of soils are being defined. Soil scientists are constantly reevaluating soil taxonomy as technology and science progress.
