Three groups of selected soils are distinguished based on variations in the content of two soil separates while keeping the third one approximately constant. Soils in Group 1 () vary along the silt and sand axis. Soils in Group 2 () vary along the clay and sand axis. Soils in Group 3 (•) vary along the silt and clay axis. Open squares represent all other soils in the database.
