ECBE.Anionic Aquic Acrustox

Key to Subgroups 

ECBE. Other Acrustox that have, within 125 cm of the mineral soil surface, both:

1. A delta pH (KCl pH minus 1:1 water pH) with a 0 or net positive charge in a layer 18 cm or more thick; and

2. Redox depletions with a color value, moist, of 4 or more and chroma of 2 or less and also aquic conditions for some time in normal years (or artificial drainage). Anionic Aquic Acrustox 

Description of Subgroups 

ECBE. Anionic Aquic Acrustox.—These soils have, in one or more horizons within 125 cm of the mineral soil surface, redox depletions with a color value, moist, of 4 or more and chroma of 2 or less and also aquic conditions for some time in normal years (or artificial drainage). They have a delta pH (KCl pH minus 1:1 water pH) with a 0 or net positive charge in a layer 18 cm or more thick within 125 cm of the mineral soil surface. These soils are not known to occur in the United States.
