The general rule is that a soil is classified as aHistosol if half or more of the upper 80 cm is organic.Dominant SubordersFibristsFibrists are the wet, slightly decomposed Histosols. The largest extent is in southern Alaska. Mostof the soils support natural vegetation of widely spaced, small trees, shrubs, forbs, and grassesand grass-like plants.


FolistsFolists are the more or less freely drained Histosols that consist primarily of horizons derivedfrom leaf litter, twigs, and branches resting on bedrock or on fragmental materials. The largestextent is in Hawaii and Alaska. Some Folists developed in the mountains and the most humidparts of the conterminous United States. Most of these soils support forest vegetation. Some ofthe soils in Hawaii mainly support grass. A few of the soils in Hawaii are used for specialty cropsor for urban or recreational development.HemistsHemists are the wet Histosols in which the organic materials are moderately decomposed. Thelargest extent is in Minnesota and Alaska. Most Hemists support natural vegetation and are usedas woodland, rangeland, or wildlife habitat. Some have been cleared and drained and are used ascropland.SapristsSaprists are the wet Histosols in which the organic materials are well decomposed. The largestextent is in Michigan, Florida, Wisconsin, Minnesota, and Alaska. Small areas are common on theAtlantic and gulf coasts. Many Saprists support natural vegetation and are used as woodland,rangeland, or wildlife habitat. Some of the soils, mostly those with a mesic or warmertemperature regime, have been cleared and drained and are used as cropland.< Back to Histosols DescriptionBack to Top NRCS Soils Home | Site Map | Contact | Accessibility | NRCS | USDA
