5.) Weighted average organic carbon content is 2 percent in upper 50 cm of soil (i.e., Humic qualifier).<br />
6.) Since new material is less than 50 cm thick, the buried soil is classified at the first level.<br />

These horizons constitute the "surface mantle of new soil material" as defined for buried soils in Chapter 1 of Soil Taxonomy and the Keys to Soil Taxonomy. Their aggregate thickness (47 cm) is<br />
within the range of 30 to 50 cm and equals at least half of the total thickness (i.e., 36 cm × 0.5 = 18 cm) of the named diagnostic horizons that are preserved in the buried soil. The current<br />
classification (based on KST, 2010) reflects presence of a buried soil.<br />
The ICOMANTH classification reflects the presence of human-transported material (HTM) on a constructional anthropogenic landform (landfill) and less than 50 cm of HTM mantling the<br />
underlying genetic horizons (formed in an older deposit of HTM).<br />
Pedon would classify in either the methanogenic or subsidic class if the proposed control section for human-altered and human-transported material classes extended to 200 cm.<br />
Is the Escalic qualifier intended only for agricultural terraces?<br />
The Transportic qualifier was used alone without the Novic qualifier to avoid redundancy. Is the Novic qualifier intended for natural parent materials instead of human-made materials?<br />
