| minimal profile development | Entisol |
| Just beginning to see a B horizon | Inceptisol |
| -Have a melanic epipedon -Fertile, easy to till, but often need P fertilizer | Andisol |
| -Have permafrost (layer of soil frozen year-round) -Loss due to climate change – may further accelerate | Gelisol |
| -minimal to no oxygen -can be used for agriculture if drained, require lime -important carbon sink -can hold a lot of water | Histisol |
| -Low soil moisture regime -Minimal development -Ochric horizon -Calcium carbonate accumulation | Aridisol |
| -Has “high-activity” clays that swell when wet, shrink when dry -dark due to mineral composition | Vertisol |
| In grasslands, grain growing areas | Mollisol |
| – High Al (aluminum) and Fe (iron) -semiarid – humid -argillic or natric horizon | Alfisol |
| -Associated with forests -Leached -Argillic horizon | Ultisol |
| -Under coniferous forests -Albic horizon -Sandy, highly leached, acidic | Spodosol |
| In hot, humid areas (tropical rainforest) | Oxisol |
