DELETE ME SERIES
The Delete me series consists of deep, well drained soils that formed in fine textured residuum from shale. Delete me soils are on uplands and have slopes of 0 to 7 percent. The mean annual precipitation is about 16 inches. The mean annual air temperature is about 43 degrees F.
TAXONOMIC CLASS: Fine, mixed, superactive, mesic Aridic Argiustolls
TYPICAL PEDON: Delete me silt loam, rangeland. (Colors are for dry soil unless otherwise stated.)
A1--0 to 4 inches; brown (10YR 5/3) silt loam, dark brown (10YR 3/3) moist; weak fine granular structure; slightly hard, friable, slightly sticky and slightly plastic; many fine and very fine roots; common fine tubular pores; neutral; clear smooth boundary. (4 to 7 inches thick)
B1--4 to 11 inches; brown (10YR 5/3) silty clay loam, dark brown (10YR 3/3) moist; weak medium prismatic structure; hard, firm, slightly sticky and plastic; many fine and very fine roots; common fine tubular pores; neutral; clear smooth boundary. (3 to 8 inches thick)
B21t--11 to 16 inches; brown (10YR 5/3) silty clay, dark brown(10YR 3/3) moist; moderate medium prismatic structure parting to moderate medium subangular blocky; very hard, very firm, slightly sticky and very plastic; common fine roots; common fine tubular pores; thick clay films on faces of peds; calcareous; neutral; clear smooth boundary. (3 to 7 inches thick)
B22t--16 to 21 inches; light brownish gray (10YR 6/2) silty clay, brown (10YR 4/3) moist; moderate fine angular blocky structure; very hard, very firm, slightly sticky and very plastic; few fine roots; common fine tubular pores; many thick clay films on faces of peds; calcareous; slightly alkaline; gradual smooth boundary. (5 to 14 inches thick)
B23ta--21 to 30 inches; pale brown (10YR 6/3) silty clay, brown (10YR 5/3) moist; weak fine subangular blocky structure; hard, firm, slightly sticky and very plastic; few fine roots; common fine tubular pores; calcareous, calcium carbonate segregated into medium, irregular, soft masses; moderately alkaline; gradual smooth boundary. (6 to 14 inches thick)
Cca--30 to 64 inches; light yellowish brown (10YR 6/4) silty clay loam, yellowish brown (10YR 5/4) moist; weak coarse prismatic structure; hard, firm, slightly sticky and plastic; few fine roots; few fine vesicular and few fine tubular pores; calcareous; calcium carbonate segregated into few fine irregular soft masses; moderately alkaline.
TYPE LOCATION: Colfax County, New Mexico; 75 feet south and 1,400 feet east of the NW corner section 26, T.26N., R.24E.
RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 24 to 40 inches. Depth to pedogenic lime ranges from 16 to 30 inches. The mollic epipedon is 7 to 20 inches thick.
The A horizon has hue of 10YR or 7.5YR, value of 4 or 5 dry and chroma of 2 or 3. It is silt loam, loam, fine sandy loam or silty clay loam.
The B21t horizon has hue of 10YR or 7.5YR, value of 4 through 6 dry, 3 through 5 moist, and chroma of 2 through 4. The B22t horizon has hue of 10YR or 7.5YR, value of 5 or 6 dry, 4 or 5 moist, and chroma of 3 through 5. The Bt horizon is silty clay, clay, or silty clay loam and has 35 to 50 percent clay. In some pedons, lime in the B23tca horizon is segregated into fine threads on faces of peds or into fine irregular soft masses.
The C horizon has hue of 7.5YR or 10YR, value of 6 or 7 dry, 4 through 7 moist, and chroma of 3 or 4. It is clay loam or silty clay loam.
COMPETING SERIES: These are the
Carnero,
Concho,
Cueva, Cunico (T),
Falfa (T),
Partri,
Quivera,
Remunda, and Sotella (T) series. Concho soils have a B2t horizon less than 16 inches thick. Carnero, Cueva, and Sotella soils have bedrock at depths of 20 to 40 inches. Cunico soils are calcareous within depth of 6 inches. Falfa soils have hue redder than 7.5YR in the B2t horizon. Partri soils have a calcic horizon immediately below the argillic horizon. Remunda soils are noncalcareous in the argillic horizon. Quivera soils have a gravelly solum that is 20 to 40 inches thick and contains 15 to 30 percent gravel.
GEOGRAPHIC SETTING: Delete me soils are on uplands at elevations of 5,900 to 7,500 feet. Slopes range from 0 to 7 percent. The soils formed in fine textured residuum weathered from shale. This material is 4 to 10 feet thick over shale. The climate is semiarid continental with mean annual temperature of 45 to 52 degrees F. The mean annual rainfall is about 14 to 18 inches with more than 3/4 received during the period of April through September. The frost free season is about 130 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Colmor,
La Brier,
Litle,
Mion,
Seelez and
Vermejo soils. Colmor, Litle, Mion, Seelez and Vermejo soils lack argillic horizon. La Brier soils have slickenslides within depth of 10 inches.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; slow permeability.
USE AND VEGETATION: Used mainly for native range. Vegetation is blue grama, wolftail, buffalograss, western wheatgrass, and galleta. Where irrigated, alfalfa, small grain, and feet sorghums are common crops.
DISTRIBUTION AND EXTENT: Northeastern New Mexico. This soil is of moderate extent.
