Official Series Description - NUMA Series <br />fertilization, and larger than normal yearly returns of organic matter. <br />A horizon: <br />Hue: 2.SY to 7.SYR <br />Value: 5 to 7, 3 to 6 moist <br />Chroma: 1 to 4 <br />Reaction: moderately or strongly alkaline (1:5 dilution unbuffered organic dye) <br />Ck horizon: <br />Hue: 2.SY to 7.SYR <br />Calcium carbonate equivalent: 15 to 40 percent <br />Page 2 of 3 <br />COMPETING SERIES: These are the Abra, Biehams Bowdish, Copeman, Creel, Darvev, Hernandez, Honlu, Kimera, <br />Peachsprings and Xenmack series. <br />Abra and Hernandez soils lack aman-made enriched Ap horizon. <br />Bighams and Bowdish soils have a paralithic contact at depths of less than 102 centimeters (40 inches). <br />Coneland soils formed in medium textured alluvial sediments overlying skeletal sediments related to high energy flows. <br />Creel soils depth to soft sandstone is 51 to 102 centimeters (20 to 40 inches). <br />Darvey soils have a Iambic horizon and in addition are dryer in the spring. <br />Honlu soils formed in slope alluvium and colluvium derived from sedimentary and metamorphic rocks. <br />Kimera soils formed in alluvium and eolian deposits derived from sedimentary rock. <br />Peachsprings soils are on fan terraces at elevations of 1311 to 1554 meters (4300 to 5100 feet). <br />Xenmack soils are on risers of strath terrace remnants at 1707 to 1951 meters (5,600 to 6,400 feet). <br />GEOGRAPHIC SETTING: <br />Landform: nearly level to gently sloping terraces, flood plains, and alluvial fans. <br />Slopes: 0 to 6 percent or more <br />Parent material: thick medium to moderately fine textured alluvium or pedisediments of mixed origin <br />Mean annual precipitation: 38 centimeters (15 inches) with peak periods of precipitation in the spring and early summer <br />months <br />Mean annual temperature: 11 degrees C. (52 degrees F.) <br />Mean summer temperature: 26 degrees C. (79 degrees F.) <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Harvev and Neesopah soils. <br />Harvey soils lack the man-made enriched Ap horizons that characterize the Numa series. <br />Neesopah soils have an argillic horizon, are moderately coarse textured, and lack a calcic horizon. <br />DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: <br />Drainage: well drained <br />Runoff: low to very low <br />Saturated Hydraulic Conductivity: moderately high to high <br />~= <br /> <br />USE AND VEGETATION: Used as irrigated cropland. "" --_ _,, <br />Principal irrigated crops are alfalfa, small grain, corn, sorghum, truck crops, and melons. _~~ <br />DISTRIBUTION AND EXTENT: The Arkansas Valley, Colorado. The series is of small extent. <br />MLRA OFFICE RESPONSIBLE: Salina, Kansas <br />SERIES ESTABLISHED: Prowers County, Colorado, 1963. <br />REMARKS: Diagnostic horizon and features recognized in this pedon are: <br />Soil last updated by the state 4/73. <br />http://www2. ftw.nres.usda.gov/osd/dat/N/NUMA.html <br />11 /02/2006 <br />
