KEEF.Vitrandic Haploxerepts

Key to Subgroups 

KEEF. Other Haploxerepts that have, throughout one or more horizons with a total thickness of 18 cm or more within 75 cm of the mineral soil surface, one or both of the following:

1. More than 35 percent (by volume) fragments coarser than 2.0 mm, of which more than 66 percent is cinders, pumice, and pumicelike fragments; or

2. A fine-earth fraction containing 30 percent or more particles 0.02 to 2.0 mm in diameter; and

                a. In the 0.02 to 2.0 mm fraction, 5 percent or more volcanic glass; and

                b. [(Al plus 1/2 Fe, percent extracted by ammonium oxalate) times 60] plus the volcanic glass (percent) is equal to 30 or more. Vitrandic Haploxerepts 

Description of Subgroups

KEEF. Andic and Vitrandic Haploxerepts.—These soils have a layer or a surface mantle, 18 cm or more thick, that has some andic soil properties and that has many of the properties of Andisols. In addition, some Andic and Vitrandic Haploxerepts have an umbric epipedon. Andic and Vitrandic Haploxerepts are of small extent. Slopes are gentle to very steep. The native vegetation consists mostly of coniferous forest. Many of these soils support their native vegetation and are used as forest. Many of the less sloping soils have been cleared and are used as cropland or pasture.
