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
