Soil Science Department, North Carolina State University
This interactive site from North Carolina State University shows the kinds of soils developed from different silt, sand, and clay content levels. A ternary diagram shows the range of soil textures based on percentages of each component. The site also provides an example of how to determine the soil texture of a sample composition. Students are also able to enter the percent composition of sand, silt, and clay and predict the soil texture classification themselves.
