| A soil that has a relatively high content of clay particles | Clayey |
| Arrangement of individual grains of sand, silt and clay into larger units called aggregrates, or peds | Structure |
| Structure is roughly sperical, like Grape Nuts...usually 1-10 mm in diameter | Granular |
| Structure consists of peds that lie horizontally in the soil | Platy |
| Structure consists of peds that are roughly cube-shaped with more less flat surfaces | Blocky |
| In the structure, the peds are taller than tehy are wide, often with five sides | Prismatic |
| Every grain acts independently and there is no binding agent to hold the grains together into peds | Single Grain |
| This type is compact, coherent soil not separated into peds of any kind | Massive |
| Improves soil structure | Adding Organic Matter |
| A single unit of soil structure | Aggregate |
