|
Histosols that are saturated with water for less than 30 cumulative days during normal years (and are not artificially drained). |
|
|
Other Histosols that:
- Have more thickness of fibric soil materials than any other kind of organic soil material either:
- In the organic parts of the subsurface tier if there
is no continuous mineral layer 40 cm or more thick
that has its upper boundary within the subsurface tier;
or
- In the combined thickness of the organic parts
of the surface and subsurface tiers if there is a
continuous mineral layer 40 cm or more thick that
has its upper boundary within the subsurface tier;
and
- Do not have a sulfuric horizon that has its upper boundary within 50 cm of the soil surface; and
- Do not have sulfidic materials within 100 cm of the
soil surface. |

Other Histosols that have more thickness of sapric
soil materials than any other kind of organic soil materials either:
- In the organic parts of the subsurface tier if there is no continuous mineral layer 40 cm or more thick that has its upper boundary within the subsurface tier; or
- In the combined thickness of the organic parts of the surface and subsurface tiers if there is a continuous mineral layer 40 cm or more thick that has its upper boundary within the subsurface tier.
