Key to Subgroups
IECC. Other Palexerolls that have, in one or more horizons within 75 cm of the mineral soil surface, redox depletions with chroma of 2 or less and also aquic conditions for some time in normal years (or artificial drainage). Aquic Palexerolls
Description of Subgroups
IECC. Aquic Palexerolls.—These soils have redox depletions with low chroma and either have shallow ground water at some time of the year or are artificially drained. They developed in nearly level or gently sloping areas where they receive more moisture than the amount that falls on the surface. The native vegetation is dominantly grasses and shrubs, but some of the soils support trees, mostly oak species. The soils are of very small extent in the Western United States. They are used mostly as cropland or pasture, some of which is irrigated.
