2/12/2014 <br />Official Series Description - W UD Series <br />Monogram soils: have calcium carbonate equivalent of 40 to 70 percent in the calcic horizon and a lithic contact <br />at 168 cm, 66 inches. <br />Snapi ll soils: have a paralithic contact at depths of 50 to 100 cm, 40 to 60 inches. <br />Tetilla soils: have 10 to 25 percent rock fragments in the Bk2 horizon. <br />Villed sods: have a lithic contact at depths of 50 to 100 cm, 40 to 60 inches. <br />Witt soils: the soil moisture control section is driest during May and June and have hues redder than l OYR. <br />GEOGRAPHIC SETTING: <br />Landform: plains and interfluves <br />Slopes: range from 0 to 12 percent <br />Parent material: loess <br />Mean annual precipitation: 254 to 356 millimeters (10 to 14 inches), most of which falls during the months of <br />April through September. Driest period is December through February. <br />Mean annual air temperature: 9 to 12 degrees C. (49 to 53 degrees F.) <br />Average summer temperature: 20 to 23 degrees C. (68 to 74 degrees F.) <br />Frost -free season: 130 to 175 days <br />Elevation ranges from 1219 to 1981 meters (4,000 to 6,200 feet). <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bacid, Manzanola, Minnequa and For soils. <br />Bacid and Manzanola soils are in the fine &roily and are in depressions and drainageways. Minnequa sow are on <br />pediments that have a thin loess cap over residuum. They have a paralithic contact at depths of 51 to 100 cm. <br />Fort soils have a fine -loamy control section and are on side slopes of interQuves and ridges. <br />DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; low or medium runoff; <br />moderately high to high hydraulic conductivity. <br />USE AND VEGETATION: These sods are rangeland or nonin ted cropland. Native vegetation is mainly <br />blue grama, galleta, sand dropseed, and western wheatgrass. It is correlated to the Loamy Ecological Site <br />Description. <br />DISTRIBUTION AND EXTENT: MLRA 69. This series is extensive. <br />MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado <br />SERIES ESTABLISHED: Lincoln County, Colorado, 1996. <br />REMARKS: Diagnostic horizons and features in this pedon are: <br />Ochric epipedon: 0 to 15 centimeters (0 to 6 inches). <br />Argillic horizon: 15 to 76 centimeters (6 to 30 inches). <br />Calcic horizon: 76 to 200 centimeters (30 to 79 inches). <br />The Wilid series replaces Wiley in the Ustic -Aridic moisture regime. The Wiley series was reclassified from Ustic <br />Haplargids to Aridic HaplustalS. The name Wilid is coined from Wiley. <br />LC 11/2011 Revised horizon nomenclature, properties ranges, and updated to metric format based on <br />reexamination of correlation samples, documentation, and field office laboratory measurements. <br />https://soiIseries.sc.egov.usda.gov/OSD_Docs=AMLID.htA 3/4 <br />
