| Conclusion
Using
the new data from the NRCS, the profile of pit #2 best fits the
description of Scotah soil. Also,
pit #2 is located in the Scotah unit on the NRCS map (Meyer, personal
communication 2001). The
high flat, with an elevation between 600 and 900 feet, has a slope of 0
to 3%. Our pit has
horizons, colors, and textures similar to those of Scotah soil.
Due to the high sand content of our soil, it is well-drained with
rapid permeability. Corn cultivation is also common. Using
the old data from the Soil Survey of Dunn County, Wisconsin, the profile
of pit #2 best fits the description of Plainbo soil (ref).
This is based on the fact our pit has horizons, colors, textures,
and slope features similar to those of Plainbo soil. The water capacity of this soil is low, and it has rapid
permeability. Plainbo soil
is commonly used for corn cultivation, as was the area including and
surrounding our pit. There
is underlying sandstone bedrock, which is also consistent with the
description of typical Plainbo soil.
