10/1342016 Official Series Description- MINNEQUA Series <br />Penrose soils have a lithic contact at depths of less than 50 centimeters (20 inches)and are on scarps. <br />Manvel, Minnequa, and Penrose soils often occur in toposequence. <br />DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: <br />Drainage: well drained <br />Saturated hydraulic conductivity: moderately high to moderately low. <br />USE AND VEGETATION: Acreage is in rangeland or nonirrigated and irrigated cropland. <br />Native vegetation is blue grama, buffalograss, western wheatgrass, galleta, cactus, and snakeweed. <br />DISTRIBUTION AND EXTENT: Southeastern Colorado, western South Dakota, and adjacent parts of Kansas <br />and Nebraska. The series is extensive. <br />MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado <br />SERIES ESTABLISHED: Arkansas Valley Area, Colorado, 1926. <br />REMARKS: Diagnostic horizons and features in this pedon are: <br />Ochric epipedon: the zone from 0 to 15 centimeters (0 to 6 inches) (A horizon) <br />Calcic horizon: the zone from 43 to 89 cm (17 to 35 inches). <br />Paralithic contact: soft chalk and marl at 89 centimeters (35 inches) (Cr horizon) <br />Moisture regime: aridic bordering on ustic. <br />The assignment of the cation -exchange activity class is inferred from lab data from similar soils in the <br />surrounding area. <br />Taxonomic Version: Eleventh Edition, 2010. <br />Modified format by LRM in 10/2005 to include metric conversion and change permeability to saturated <br />hydraulic conductivity. <br />LAN 1/16/2013 The previous classification of calcareous Ustic Torriorthents became obsolete with the Eleventh <br />Edition to Keys to Soil Taxonomy. Based on a field project this update moves the type location from Prowers <br />County to Pueblo County, Colorado and changes the Taxonomic class to Fine -silty, mixed, superactive, mesic <br />Ustic Haplocalcids. <br />National Cooperative Soil Survey <br />U.S.A. <br />https://soilseries.sc.egov.Lisda.gov/OSD—DoGs/M/MINNEQUAhtmi 343
