10/13/2016 Official Series Description - MANVEL Series pedons. Depth to visible calcium carbonate accumulations: 8 to 38 cm (3 to 15 inches) Calcium carbonate equivalent: 15 to 40 percent in at least one horizon above a depth of 100 cm (40 inches). Electrical conductivity: 0.5 to 8 dS/m Particle size control section: (Weighted average) Clay content: 18 to 27 percent Silt content: 40 to 70 percent Sand content: 5 to 35 percent, with less than 15 percent fine or coarser sand Rock fragment content: 0 to 5 percent in the control section A horizon: Hue: IOYR to 2.5Y Value: 5 or 6 dry, 3 to 5 moist Chroma: 2 to 4 Texture: silt loam or loam Clay content: 18 to 27 percent Reaction: slightly alkaline to strongly alkaline Bk horizons: (Bw in some pedons) Hue: 7.5YR to 2.5Y Value: 5 to 8 dry, 4 to 6 moist Chroma: 3 to 6 Texture: silt loam, loam, clay loam or silty clay loam Clay content: 15 to 35 percent but is typically 18 to 27 percent. Reaction: moderately alkaline to strongly alkaline Calcium carbonate equivalent: 10 to 40 percent Rock fragment content: 0 to 5 percent above a depth of 100 cm (40 inches), 0 to 15 percent below 100 cm. COMPETING SERIES: These are the Minnequa (CO), and Willard (NM) series. Minnequa soils: have a paralithic contact at depths of 50 to 100 centimeters (20 to 40 inches). Willard soils: are in MLRA 70, are dry in March and intermittently moist in April and May, formed in lacustrine deposits, have iron masses in the Bw, and salt crystals in the Bk horizons. GEOGRAPHIC SETTING: Landform: fans and plains, interfluves Slopes: 0 to 15 percent. Parent material: calcareous alluvium derived from chalk, shale and soft limestone. Average annual precipitation: 254 to 356 millimeters (10 to 14 inches) wettest period: May through August Driest period: December through February Average annual air temperature: 9 to 14 degrees C. (48 to 57 degrees F.) Average summer temperature: 20 to 26 degrees C. (68 to 78 degrees F.) Elevation is 1,006 to 1,981 meters (3,300 to 6,500 feet) Frost free season: 125 to 170 days. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Penrose, Tyrone, and MdlW series, and the competing Minnequa series. Penrose soils have a lithic contact at depths of less than 50 centimeters and are on scarps. Tyrone soils have a natric horizon. Wilid soils have an argillic horizon and are on interfluves. DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Drainage: Well drained Saturated Hydraulic Conductivity: high or moderately high. httpsY/scilseries.sc.egov.Lisda.gov/OSD_Docs/M/MANVELhtmi 2/3
