| Describer: Anthony Khiel, Mark Hudson, Tiffany Smith | County: Sevier |
| Site ID: S2015TN155400 | MLRA: 130B -- Southern Blue Ridge |
| Site Note: | Soil Survey Area: TN155 -- Sevier County, Tennessee SS0130 -- Blue Ridge MLRA Soil Survey 6-WAY -- Waynesville, North Carolina |
| Pedon ID: S2015TN155001 | Map Unit: SsC -- Spivey-Santeetlah-Nowhere complex, 8 to 15 percent slopes, very stony |
| Pedon Note: Pedon sample area: No "O" horizons were described due to the lack of decomposed leaf litter. Last seasons' leafs are present, but no Oa,e, or i material is present at the sample location. ; Nutrient recycling in the upper layers. Roots are concentrated in the Surface horizons (A1 & A2) and all root size categories are described as many; roots decrease quickly with depth. Roots are in the surface layers due to higher organic matter, more than adequate rainfall (>50"/year), and low nutrients in the subsoil (Thunderhead Sandstone). | Quad Name: Gatlinburg, Tennessee |
