HENNINGS SERIES


The Hennings series consists of deep, well drained, moderately permeable soils on uplands. They formed in loamy material and the underlying soft calcareous sandstone. Slopes range from 0 to 20 percent. Mean annual temperature is about 47 degrees F, and the mean annual precipitation is about 19 inches.

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Typic Argiustolls

TYPICAL PEDON: Hennings fine sandy loam, on a 4 percent convex northeast-facing slope reseeded to grass. When described the soil was dry throughout. (Colors are for dry soil unless otherwise stated)

Ap--0 to 7 inches; grayish brown (10YR 5/2) fine sandy loam, very dark grayish brown (10YR 3/2) moist; weak fine granular structure; slightly hard, very friable; many very fine and common fine roots; neutral; clear wavy boundary. (6 to 15 inches thick)

Bt1--7 to 15 inches; brown (10YR 5/3)sandy clay loam, dark brown (10YR 3/3) moist; moderate coarse prismatic structure parting to moderate medium subangular blocky; hard, firm; common very fine and fine roots;.few faint clay films on faces of peds; neutral; clear wavy boundary.

Bt2--15 to 21 inches; pale brown (10YR 6/3) loam, brown (10YR 4/3) moist; weak coarse prismatic structure parting to weak medium subangular blocky; slightly hard, friable, common very fine and fine roots; few faint clay films on faces of peds; neutral; gradual wavy boundary. (Combined thickness of Bt horizons is 7 to 20 inches).

BC--21 to 27 inches; light gray (10YR 7/2) loam, grayish brown (10YR 5/2) moist; weak coarse prismatic structure; slightly hard, very friable; common very fine and fine roots; slightly alkaline; abrupt wavy boundary. (0 to 12 inches thick)

C1--27 to 36 inches; light gray (2.5Y 7/2) fine sandy loam, grayish brown (2.5Y 5/2) moist; massive; soft, very friable; few, very fine roots; about 2 percent by volume of soft calcareous sandstone fragments ranging from 1/8 to 1/2 inch in diameter; strong effervescence; strongly alkaline; gradual wavy boundary.

C2--36 to 55 inches; light gray (2.5Y 7/2) loamy fine sand, light brownish gray (2.5Y 6/2) moist; single grain; loose; few very fine roots; about 4 percent by volume of soft calcareous sandstone fragments ranging from 1/8 to 1 inch in diameter; strong effervescence; strongly alkaline; clear wavy boundary.

Cr--55 to 60 inches; pale yellow (2.5Y 8/2) weakly cemented fine grained sandstone, light gray (2.5Y 7/2) moist; strong effervescence.

TYPE LOCATION: Cherry County, Nebraska; 8 miles south and 5 miles east of Kilgore; 2300 feet north and 600 feet east of southwest corner, sec. 21, T. 33 N,. R. 30 W. Kilgore SE topographic quadrangle: latitude 42 degrees, 49 minutes, 12 seconds North and longitude 100 degrees, 51 minutes, 48 seconds West.

RANGE IN CHARACTERISTICS: Thickness of the solum and depth to carbonates ranges from 24 to 44 inches. Thickness of the mollic epipedon ranges from 7 to 20 inches and extends into the upper part of the argillic horizon. Depth to bedrock ranges from 40 to 60 inches.

The A horizon has hue of 10YR, value of 4 or 5 and 2 or 3 moist, and chroma of 2 or 3. It is loamy fine sand or fine sandy loam. It is moderately acid through neutral.

The Bt horizon has hue of 10YR, value of 4 to 6 and 3 to5 moist, and chroma of 2 to4. It is clay loam, sandy clay loam or loam ranging from 18 to 35 percent clay. It is neutral or slightly alkaline.

The BC horizon, when present, has hue of 10YR or 2.5Y, value of 5 to 7 and 4 to 6 moist, and chroma of 2 to 4. It is fine sandy loam, very fine sandy loam, or loam. It is neutral or slightly alkaline. Some pedons have a Bk horizon.

The C horizon has hue of 10YR , 2.5Y or 5Y, value of 6 to 8 and 5 to 7 moist, and chroma of 2 to 4. It is fine sand, loamy fine sand, fine sandy loam, loam or very fine sandy loam. It is slightly alkaline through strongly alkaline.

The Cr horizon has hue of 2.5Y, value of 7 or 8, 5 to 7 moist and chroma of 2 to 4. The sandstone bedrock is weakly to strongly cemented.

COMPETING SERIES: These are the Glenham, Gosper, Houdek, Ree, Reventon, Verdigre, Wewela, and Wineg series in the same family. Glenham and Houdek soils formed in glacial till. In addition, Glenham soils have free carbonates within depths of 20 inches and Houdek soils have Bk horizons over 15 inches thick. Gosper soils formed in alluvium and typically have free carbonates at a depth of 10 to 24 inches. Ree soils have Bk horizons over 10 inches thick. Reventon soils have free carbonates within a depth of 14 inches. Verdigre soils have bedded shale at a depth between 40 and 60 inches. Wewela soils have shale bedrock within a depth of 40 inches. Wineg soils have a calcic horizon and have 14 to 16 inches mean annual precipitation.

GEOGRAPHIC SETTING: Hennings soils are on smooth uplands with convex to slightly concave surfaces. Slope gradients range from 0 to 20 percent. Hennings soils formed in loamy material and the underlying calcareous sandstone. The mean annual precipitation ranges from 17 to 20 inches, and the mean annual temperature ranges from 47 to 50 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Anselmo, Keya, Ronson, Sandose, Tassel and Valentine soils. Anselmo and Ronson soils are on similar landscapes and have a coarse-loamy control section. Ronson soils ae sandstone at a depth between 20 and 40 inches. Keya soils are in swales or shallow depressions and have a mollic epipedon more than 20 inches thick. Sandose soils have a sandy over loamy control section and occur on similar landscapes. Tassel soils are on ridge tops and shoulders and are shallow over sandstone. Valentine soils have a sandy control section and are on dunes.

DRAINAGE AND PERMEABILITY: Well drained. Runoff is low to high depending on the degree of slope. Permeability is moderate.

USE AND VEGETATION: Used as cropland and rangeland. Common crops are small grains, alfalfa, and irrigated corn, Native vegetation is dominated by little bluestem, blue grama, needleandthread, prairie sandreed, and sand bluestem.

DISTRIBUTION AND EXTENT: North-central Nebraska. The series is moderately extensive.

SERIES ESTABLISHED: Cherry County, Nebraska, 1995.

REMARKS: Some areas of these soils have previously been included with the Tuthill soils.

Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface of the soil to a depth of 15 inches (Ap, Btl horizons); argillic horizon - the zone from 7 to 21 inches (Btl, Bt2 horizons).

ADDITIONAL DATA: Pedons sampled for National Soil Survey Lab and Nebraska Department of Roads.
