| List I (Diagnostic characteristics) |
List II (Soil order) |
| A. Clay rich, presence of smectite type of clay mineral |
I. Alfisols |
| B. Frigid and pergelic soil temperature regime |
II. Inceptisols |
| C. Immature soil, presence of cambic, umbric, and mollic horizon |
III. Vertisols |
| D. Ochric epipedon with an argillic subsurface horizon |
IV. Gelisols |
A – III (Vertisols): High clay content, especially smectite, which causes shrink-swell behavior.
B – IV (Gelisols): Found in cold climates with frigid/pergelic temperature regimes.
C – II (Inceptisols): Immature soils with weak horizon development.
D – I (Alfisols): Have an ochric epipedon and argillic (clay-enriched) B horizon, common in semi-arid to humid climates.
