Official Series Description - ~N 5enes • rage s or s <br />Lamo and Leshara soils are fine-silty. <br />Platte soils are shallow to coarse sand, gravelly sand or gravelly coarse sand. Ord soils have sand at 20 <br />to 35 inches and are more clacareous. <br />DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: <br />Drainage: somewhat poorly drained <br />Runoff: slow <br />Saturated hydraulic conductivity: Very High <br />The seasonal high water table: 46 centimeters (18 inches) wet years to 107 centimeters (42 inches) dry <br />years <br />Flooding: rare or common, brief durations <br />LSE A1SD VEGETATiO1S: lViost areas are cultivated. <br />The principal crops are alfalfa, corn, grain sorghum, and soybeans. Many areas are irrigated. <br />Native grasses are big bluestem, switchgrass and Indiangrass. <br />DISTRIBUTION AND EXTENT: In the central, eastern, and southern parts of Nebraska and <br />Colorado, Kansas, Oklahoma, and South Dakota. They are most extensive along the Platte River, the <br />Republican River, and their tributaries. Wann soils are of large extent. <br />MLRA OFFICE RESPONSIBLE: Salina, Kansas <br />SERIES ESTABLISHED: Washington County, (Akron Area), Colorado, 1938. <br />REMARKS: Diagnostic horizons and features recognized in this pedon are: Carbonates: 0 to 38 <br />centimeters (0 to 15 inches), but in the eastern extent leached to 61 centimeters (24 inches), <br />Further study is needed to determine if this series is calcareous. <br />Phases of Wann soils correlated to date include saline, alkali, and saline-alkali. <br />11/2005 JCR LM changed to semi-tab format, added metric conversion and saturated hydraulic <br />conductivity. <br />National Cooperative Soil Survey <br />U.S.A. <br />http://ortho.ftw.nres.usda.gov/cgi-bin/osd/osdname.cgi?-P .1/27/2006 <br />
