Soil Monolith

Soil Monolith

 

sample of a soil profile with undisturbed structure, including several or all the basic genetic horizons. These samples are used as visual aids for the study of soils at educational institutions, for demonstrating the external characteristics of soil types and species at exhibitions and in museums, and for laboratory experiments. The standard soil monolith is considered to be a sample placed in a wooden box with dimensions (in centimeters) of 100 × 20 × 6–8. Film soil monoliths up to 1 cm thick are also common; they are used only for demonstration purposes.
