Polygenetic upland soils of east central Kansas have been formed though multiple and likely different sets of soil forming factors. Upland soils in this region have a complex genesis, often contain one or more paleosols, and form in multiple parent materials including loess, locally reworked loess or colluvium, and residuum. The depth to bedrock rarely exceeds 2 m. Upland hillslope soils commonly contain one or more paleosols, and can be observed on a variety of hillslope positions on the landscape. Generally, the lower paleosols are recognized by strongly expressed structure, thick continuous clay coatings on all faces of peds, and strong reddish color with either 7.5YR or 5YR hues. Soil textures of the paleosols often feel less clayey than the overlying horizons in field determinations. At first, this was attributed to a decrease in clay content, stickiness, and plasticity. However, subsequent laboratory characterization revealed that the clay content was usually highest in the lower paleosol horizons, and that the clay mineralogy of the modern soil was dominated by smectite, while the paleosols contained a mixed suite of minerals. Therefore, the perceived decrease in clay content was caused by a change in clay mineralogy, a feature that can be exploited in future field descriptions in order to more accurately distinguish between stratigraphic units in these thin, welded polygenetic soils. The age of the paleosols sampled in this study were typical for the late Quaternary-aged Severance formation, clustering in two age ranges, which were ≈ 19,000 to 20,000 and ≈ 22,500 to 27,700 uncalibrated 14C yr BP. The results from this study illustrate that although they might be thin, truncated, and welded, late Quaternary-aged loess-derived soils and paleosols occur in regular, predictable patterns on many upland hillslopes in the Bluestem Hills Major Land Resource Area, and this region should be included in future regional investigations of the Central Plains.10aCentral Plains10aGreat Plains10aLandscapes10aLoess10aMineralogy10aPaleosols10aQuaternary1 aPresley, D.R.1 aHartley, P.E.1 aRansom, M.D.  uhttp://knz.lternet.edu/content/mineralogy-and-morphological-properties-buried-polygenetic-paleosols-formed-late-quaternary00576nas a2200205   4500008004100000245002500041210002500066260003800091300001100129653002200140100001700162700001700179700001500196700002100211700002000232700001900252700001900271700002400290856005600314       1998                        eng d00aSoils and soil biota0 aSoils and soil biota  aNew YorkbOxford University Press  a48 -6610atallgrass prairie1 aRansom, M.D.1 aRice, C., W.1 aTodd, T.C.1 aWehmueller, W.A.1 aKnapp, Alan, K.1 aBriggs, J., M.1 aHartnett, D.C.1 aCollins, Scott., L.  uhttp://knz.lternet.edu/content/soils-and-soil-biota00658nas a2200169   4500008004100000245009100041210006900132260005400201300001300255490000700268100002100275700001700296700002000313700002500333700002000358856011000378       1993                        eng d00aMicromorphology of polygenetic soils in a small watershed, north central Kansas, U.S.A0 aMicromorphology of polygenetic soils in a small watershed north   aTownsville, AustraliabElsevier Science Publisher  a247 -2550 v221 aWehmueller, W.A.1 aRansom, M.D.1 aNettleton, W.D.1 aRingrose-Vaose, A.J.1 aHumphreys, G.S.  uhttp://knz.lternet.edu/content/micromorphology-polygenetic-soils-small-watershed-north-central-kansas-usa01570nas a2200169   4500008004100000245007300041210006900114300001100183490000700194520102100201653002201222100001101244700001901255700001701274700001301291856009601304       1990                        eng d00aSeparability of soils in a tallgrass prairie using SPOT and DEM Data0 aSeparability of soils in a tallgrass prairie using SPOT and DEM   a10 -170 v323 a<p>A sufficient transformation technique is important in using computer-aided soil pattern recognition to interpret soils in soil surveys. This study was conducted using the Systeme Probatoire d&#39;Observation de la Terre (SPOT) satellite images and Digital Elevation Model (DEM) data to seperate five major sils in a tallgrass prairie near Manhattan, Kansas. The high resolution SPOT satellite im;ages were integrated with DEM data. the soils were sampled and classified using conventional soil survey procedures to extract the important soil features from SPOT and DEM data. A pairwise transformed divergence analysis was also conducted to evaluate the several aanonical variables in order to sufficiently separate the soils. Consequently, two canonical variables derived from training samples were selected. Our results suggest that canonically transformed data were superior to combined SPOT and DEM data.

Digital Elevation Model (DEM) data were merged to Landsat TM and SPOT data to delineate soil mapping units within the study area. Soil mapping units from a conventional soil survey were compared with a classified soil spectral map obtained from Landsat TM or SPOT, and DEM derived elevation, slope, and aspect data, using an overall accuracy assessment. The overall accuracy of soil spectral classesfrom TM and SPOT data were merged. A higher average accuracy for soil mapping units was obtained with a low frequency filtering transformation of the data. For Landsat TM data, Band 5 (middle infrared, 1.55-1.75 æm) was most useful for soil information extraction, and a higher overall accuracy was obtained in the dormant season compared with the accuracy in the growing season. The overall accuracy (about 57%) from SPOT data was slightly higher than the accuracy (about 53%) from Landsat TM at a similar wavelength range.
