BBBG.Typic Sphagnofibrists

Key to Subgroups 

BBBG. Other Sphagnofibrists. Typic Sphagnofibrists 

Description of Subgroups 

BBBGTypic Sphagnofibrists.—The central concept or Typic subgroup of Sphagnofibrists is fixed on thick, continuous fibric organic materials that were derived primarily from Sphagnum. These soils do not have a lithic contact and do not have a layer of water within the control section, below the surface tier. At least three-fourths of the fibric materials, by volume, were derived from Sphagnum. These soils occur as raised bogs or high moors in closed depressions and as blanket bogs on more or less dissected landscapes. Layers of organic material more decomposed than fibric materials affect the movement of water and indicate an intergrade to Hemists. Thin mineral layers normally affect the movement of water drastically. These layers normally are alluvial and define the Fluvaquentic subgroup. Thick mineral layers, rock, limnic layers, and water within the control section are used as bases for classifying terric, lithic, limnic, and hydric extragrades, respectively. Typic Sphagnofibrists are used mostly as wildlife habitat. A few have been cleared and are used for specialty crops. These soils are of small extent in the United States.
