| Pedon Note: This pedon is named Poplimento-like due to the fact that the solum thickness does not meet the required range of 40 to 70 inches (102-178 cm) and the drainage class is moderately well drained.; The C1 and C2 horizons gray colors are dominantly clay, the redder colors are dominantly silt loam and the brownish colors are dominantly silty clay.; The C1 and C2 horizons consist of very highly weathered shale, siltstone and fine-grained sandstone fragments. The gray colors in the C1 and C2 horizons follow root channels vertically from a depth of 33-inches (84cm) to the bottom of the profile. THis same situation has been observed in areas mapped Poplimento by other soil scientists but a moderately well drained counterpart has not been established due to the olimited acreage.; The seven horizons have been sampled by the NEON staff and will be sent to the NRCAS Kellogg Lab. | Quad Name: |
