Organic

Soils mainly composed of organic peat material with Of, Om or Oh horizons, or, upland organic forest materials with L, F, H horizons > 40cm thick.

Soils that have organic horizon that extend from the surface to one of the following:

1. 60cm if the surface layer is fibric material (Of) having a bulk density of <0.075g/cm3./li>
2. A depth >40cm if the surface layer consists of mesic or humic material (Om or Oh) having a bulk density >0.075 g.cm3
3. A deth of >40cm if composed of folic materials (L, F, H), or >10cm if a lithic contact or fragmental materials are present. Folic materials must be more than twice the thickness of a mineral soil layer if the mineral layer <20cm thick.
4. 2 more conditions

Regosolic

Soils with a Bm, Btj or Bfj horizon < 5cm thick and no Bg horizon.

Brunisolic

Soils with either a Bm, Bmgj, Btj or Btj horizon > 5cm thick.

Soils with a Bm, Btj or Bfj horizon > 5cm thick, or Bf horizon <10cm thick.

Podzolic

Soils with a podzolic B horizon and no Bt horizon within 50cm of the mineral surface.

Luvisolic

Soils with a Bt horizon and no Bg horizon or podzolic B horizon if the Bt is > 50cm below mineral surface.

Gleysolic

Soils with a g horizon within 50cm of the mineral surface.
Soils that are saturated with water and under reducing conditions either continuously or during some period of the the year as indicated either by direct measurements of the water table and the oxidation - reduction status, or by morphological features within 50cm of the mineral surface.
