|The Weber Farm
Site is characterized by complex topographic expression and a
correspondingly complex soil catena. Slope and slope aspect, though
identified as the important soil forming variable in this study bear
further investigation. A detailed topographic map generated using
global positioning system (GPS) and geographic information system (GIS)
technology will quantify slope steepness and slope aspect data.
Implementation of appropriate (read: inexpensive but effective) soil
erosion control measures will depend on this data. Slope data when
combined with instrumental soil temperature, moisture, and frost-free
period data will better characterize the relationship between these
important soil and slope characteristics.
Finally, the well-expressed Bt-horizons observed at depth in some profiles are intriguing horizons. Their genesis may have important implications with regard to late glacial history of Dunn County and adjacent counties. The glacial history of Dunn County, especially the late glacial period is poorly understood. These horizons may be remnants of soils formed prior to the final glacial advance in western Wisconsin. As such, a more accurate picture of late glacial histiory will emerge once these horizons are examined in more detail to clarify their age and the environmental conditions under which they formed.
