- 14Just beginning to see a B horizonInceptisol
- 15-Have a melanic epipedon -Fertile, easy to till, but often need P fertilizerAndisol
- 16-Have permafrost (layer of soil frozen year-round) -Loss due to climate change – may further accelerateGelisol
- 17-minimal to no oxygen -can be used for agriculture if drained, require lime -important carbon sink -can hold a lot of waterHistisol
- 18-Low soil moisture regime -Minimal development -Ochric horizon -Calcium carbonate accumulationAridisol
- 19-Has “high-activity” clays that swell when wet, shrink when dry -dark due to mineral compositionVertisol
- 20In grasslands, grain growing areasMollisol
- 21– High Al (aluminum) and Fe (iron) -semiarid – humid -argillic or natric horizonAlfisol
- 22-Associated with forests -Leached -Argillic horizonUltisol
