Official Series Description-&NBERG Series • Page 2 of 2 <br /> ' Texture is also variable and is stratified loamy sand to clay loam. <br /> COMPETING SERIES: These are the Cameo(CO),Clarkelen(WY),Colorow(CO), Kornman <br /> ' (CO), Radnik(AZ), and Redbank(WY) series. Colorow soils are moderately well drained with <br /> mottles. Kornman soils have over-thickened, nitrogen and phosphate enriched man-made surface <br /> horizons resulting from application of silty irrigation water over long periods of time. Redbank soils <br /> ' have hue of 7.5YR or redder. Cameo soils are usually dry in the moisture control section more than <br /> half the time in June. Clarkelen soils have colder air temperatures than 52 degrees and growing <br /> seasons shorter than 130 days. Radnik soils are driest in the soil moisture control section in May and <br /> ' June and receive peak precipitation in July through September and December through February. <br /> GEOGRAPHIC SETTING: Glenberg soils are on alluvial fans, flood plains, valley floors, and low <br /> ' terraces. Slopes range from 0 to 8 percent. These soils formed in thick very strongly stratified <br /> alluvial sediments derived from mixed sources. At the type location average annual precipitation is <br /> 10 to 13 inches with peak periods of precipitation during the spring and early summer. Average <br /> annual air temperature is 496 to 55 degrees F., and the average summer temperature is 76 degrees F. <br /> Frost-free season is 130 to 180 days. In Utah and New Mexico, the average annual precipitation <br /> ' ranges from 8 to 13 inches, mean annual air temperature is 47 to 52 degrees F, with a frost-free <br /> season of 110 to 145 days at elevations of 5,400 to 7,000 feet. In Nebraska mean annual <br /> precipitation ranges to 17 inches. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bankard and Haverson soils. <br /> Bankard soils have a sand or loamy sand control section. Haverson soils have 18 to 35 percent clay <br /> ' in the particle-size control section. <br /> DRAINAGE AND PERMEABILITY: Well drained. runoff is negigible to low. Permeability is <br /> moderately rapid to rapid. <br /> ' USE AND VEGETATION: These soils are used primarily as pastureland and irrigated cropland. <br /> Native vegetation is blue grama, western wheatgrass, bluestem, cottonwood, and willows. <br /> DISTRIBUTION AND EXTENT: Colorado, northern New Mexico, eastern Wyoming, western <br /> Nebraska, and western Kansas. The series is of large extent. <br /> MLRA OFFICE RESPONSIBLE: Bismarck, North Dakota <br /> SERIES ESTABLISHED: Red Willow County,Nebraska, 1965. <br /> REMARKS: Diagnostic horizons and features recognized in this pedon are: thin stratifications of <br /> ' loam to loamy sand from 6 to 60 inches. <br /> National Cooperative Soil Survey <br /> ' U.S.A. <br />
