In both the World Reference Base for Soil Resources (WRB) [1] and the USDA soil taxonomy, [2] a Histosol is a soil consisting primarily of organic materials. They are defined as having 40 centimetres (16 in) or more of organic soil material starting within 40 cm from the soil surface.

Histosols are forming in organic soil materials. The general rule is that a soil is classified as a Histosol if half or more of the upper 80 cm is organic.

湿成土，指成土过程中长期或季节性（周期性）受到水分浸润或饱和的土壤。湿成土的水分含量多，有机质含量丰富，土体中物质还原作用强，在土体一定部位显灰蓝色或灰色，有锈斑和铁子等新生体。该土纲相当于美国分类的有机土（Histosols）、软土（Mollisols）及若干土纲中的“潮湿”（aquic）亚 ...

Histosol, one of the 12 soil orders in the U.S. Soil Taxonomy. Histosols are formed under waterlogged conditions typical of peat bogs, moors, and swamps. Under such conditions, the accumulated tissues of dead plants and animals and their decomposition products are preserved, resulting in soils of

2016年1月1日 · The term Histosol was first used in 1960 in the U.S. System of Soil Classification to refer to peaty soils. More recently the World Reference Base for Soils (WRB, 1998 ; FAO, 2001 ) considers Histosols as soils having a histic or folic superficial horizon (see also Zech and Hintermaier‐Erhard, 2007 ).

By eliminating field operations and fertilizer N application, histosol set-aside can reduce upstream and process emissions lead to more GHG benefits, although the production would likely shift elsewhere, so the net benefit depends on emissions in other productive regions.
