DCE.Vitricryands

Key to Subgroups

DCEA. Vitricryands that have a lithic contact within 50 cm either of the mineral soil surface or of the top of an organic layer that has andic soil properties, whichever is shallower. Lithic Vitricryands
Soil Families and Soil Series in Subgroup

DCEB. Other Vitricryands that have, in one or more horizons at a depth between 50 and 100 cm either from the mineral soil surface or from the top of an organic layer with andic soil properties, whichever is shallower, aquic conditions for some time in normal years (or artificial drainage) and one or more of the following:
1. 2 percent or more redox concentrations; or
2. A color value, moist, of 4 or more and 50 percent or more chroma of 2 or less either in redox depletions on faces of peds or in the matrix if peds are absent; or
3. Enough active ferrous iron to give a positive reaction to alpha,alpha-dipyridyl at a time when the soil is not being irrigated. Aquic Vitricryands
Soil Families and Soil Series in Subgroup

DCEC. Other Vitricryands that are saturated with water in one or more layers within 100 cm of the mineral soil surface in normal years for either or both:
1. 20 or more consecutive days; or
2. 30 or more cumulative days. Oxyaquic Vitricryands
Soil Families and Soil Series in Subgroup

DCED. Other Vitricryands that have an albic horizon overlying a cambic horizon in 50 percent or more in each pedon or have a spodic horizon in 50 percent or more of each pedon. Spodic Vitricryands
Soil Families and Soil Series in Subgroup

DCEE. Other Vitricryands that have, at a depth between 25 and 100 cm either from the mineral soil surface or from the top of an organic layer with andic soil properties, whichever is shallower, a layer 10 cm or more thick with more than 3.0 percent organic carbon and the colors of a mollic epipedon throughout, underlying one or more horizons with a total thickness of 10 cm or more that have a color value, moist, 1 unit or more higher and an organic-carbon content 1 percent or more (absolute) lower. Thaptic Vitricryands
Soil Families and Soil Series in Subgroup

DCEF. Other Vitricryands that have a xeric moisture regime and a mollic or umbric epipedon. Humic Xeric Vitricryands
Soil Families and Soil Series in Subgroup

DCEG. Other Vitricryands that have a xeric moisture regime. Xeric Vitricryands
Soil Families and Soil Series in Subgroup

DCEH. Other Vitricryands that have an argillic or kandic horizon that has both:
1. An upper boundary within 125 cm either of the mineral soil surface or of the top of an organic layer with andic soil properties, whichever is shallower; and
2. A base saturation (by sum of cations) of less than 35 percent throughout the upper 50 cm or throughout the entire argillic or kandic horizon if it is less than 50 cm thick. Ultic Vitricryands
Soil Families and Soil Series in Subgroup

DCEI. Other Vitricryands that have an argillic or kandic horizon that has its upper boundary within 125 cm either of the mineral soil surface or of the top of an organic layer with andic soil properties, whichever is shallower. Alfic Vitricryands
Soil Families and Soil Series in Subgroup

DCEJ. Other Vitricryands that have a mollic or umbric epipedon. Humic Vitricryands
Soil Families and Soil Series in Subgroup

DCEK. Other Vitricryands. Typic Vitricryands
Soil Families and Soil Series in Subgroup
