Albic horizon

Glossic Occurs usually between an overlying albic horizon and an underlying argillic, kandic, or natric horizon or fragipan. Requirements > 5 cm thick Albic material between 15% to 85%, material like the underlying horizon. [Pg.935]

Sombric Formed by illuviation of humus (darkbron to black color) but not of aluminum or sodium. Requirements At pH 7 base saturation <50% Not under an albic horizon Free-draining horizon. [Pg.935]

Albic Light-colored E horizon with the color value S5 (dry) or >4 (moist)... [Pg.934]

Soil moisture regime dry to aquic. Major soil property featureless soil bodies. Diagnostic horizons typically absent, albic. Epipedon ochric. Characteristics little or no evidence of soil development. Description recently formed soils such as land surfaces that are very young (e.g., alluvium, colluvium, mudflows), extremely hard rocks, sandy parent material, disturbed material (e.g., mined land, highly compacted soils, or toxic material disposal). Exhibit A/C or A/R profiles. May have an Ap horizon. [Pg.946]

Ultisols Aquults Vegetation forest. Climate occur in any soil temperature regime. Soil moisture Udults regime precipitation greater than evapotranspiration, xeric to aquic. Major soil Ustults property low base saturation. Diagnostic horizons argillic, kandic, albic. [Pg.948]

Leptic Podzols (PI) Other Podzols lacking or having only a thin (2 cm or less) and discontinuous albic E horizon lacking a subhorizon within the B horizon which is visibly more enriched with carbon... [Pg.951]

Albic Luvisols (La) Other Luvisols having an albic E horizon... [Pg.953]
