The term aridic properties combines a number of properties which are common in surface horizons of soils occurring under arid conditions and where pedogenesis exceeds new accumulation at the soil surface by aeolian or alluvial activity. Gleyic properties. The term secondary carbonates is preferred to soft powdery lime as used in the Revised Legend. The presence of acicular "needle-shaped" clay minerals e. Munsell colours with a chrome of less than 3. Aridic properties. It has a fair amount of organic matter and a low clay content.

    Ferralic properties. The requirements for an umbric horizon must be met after the first 20 cm are mixed, as in ploughing. This may be due to the fact that under arid conditions acicular clays are not produced but only preserved, provided they exist in the parent material or in the dust that falls on the soil.

    Ochric Epipedon The ochric epipedon fails to meet the definitions for any of the other seven epipedons because it is too thin or too dry, has too high a color value .
    Under these conditions coarse cryoclastic material dominates and there is little dust to be deflated and deposited by wind.

    It also includes soil materials which would qualify for a ferralic horizon apart for their coarse texture.

    Gleyic properties. Continuous hard rock is material underlying the soil, exclusive of cemented pedogenetic horizons such as a petrocalcic, petroduric, petrogypsic and petroplinthic horizons, which is sufficiently coherent and hard when moist to make hand digging with a spade impractible.

    In this case some part of the lower horizon should have at least twice the clay content of the upper horizon.

      The crust, which has a loamy texture, shows a polygonal network of desiccation cracks, often filled with inblown material, which extend into the underlying horizons.

      These horizons can usually be recognized in the field by the presence of artifacts, spade marks, contrasting mineral inclusions or stratification indicating the intermittent addition of manurial material, a relative higher position in the landscape, or by checking the agricultural history of the area.
