MAYBERRY SERIES


The Mayberry series consists of very deep, moderately well drained soils on uplands. They formed in reworked, weathered till. They have slopes ranging from 2 to l5 percent. Mean annual air temperature is 52 degrees F., and mean annual precipitation is 29 inches.

TAXONOMIC CLASS: Fine, smectitic, mesic Aquertic Argiudolls

TYPICAL PEDON: Mayberry clay loam on a 5 percent, west-facing slope in bromegrass. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 15 centimeters; very dark brown (10YR 2/2) clay loam, dark grayish brown (10YR 4/2) dry; weak very fine and fine subangular blocky structure parting to moderate fine granular; friable, hard; moderately acid; clear smooth boundary. (10 to 30 centimeters thick)

BA--15 to 25 centimeters; dark brown (7.5YR 3/2) clay loam; brown (7.5YR 5/2) dry; moderate very fine and fine subangular blocky structure; firm, hard; moderately acid; clear smooth boundary. (0 to 25 centimeters thick)

Bt1--25 to 76 centimeters; dark reddish brown (5YR 3/4) clay; reddish brown (5YR 4/4) dry; common fine distinct dark red (2.5YR 3/6) and prominent dark grayish brown (10YR 4/2) iron masses in the soil matrix; moderate fine and medium angular blocky structure; very firm, hard; thin discontinuous clay films on faces of peds; slightly acid; gradual wavy boundary.

Bt2--76 to 109 centimeters; brown (7.5YR 4/4) clay; brown (7.5YR 5/4) dry; few fine distinct reddish brown (5YR 4/4) iron masses in the soil matrix; moderate fine and medium angular blocky structure; very firm, hard; thin discontinuous clay films on faces of peds; common small lime concretions; neutral; gradual wavy boundary. (Combined thickness of Bt is 43 to 165 centimeters.)

BC--109 to 152 centimeters; mottled grayish brown (2.5Y 5/2) and brown (7.5YR 4/4) stratified clay and clay loam with thin lenses of silty clay loam; light gray (2.5Y 7/2) and brown (7.5YR 5/4) dry; moderate fine and medium angular blocky structure; very firm, hard; thin discontinuous clay films on faces of peds; neutral; gradual wavy boundary. (15 to 51 centimeters thick)

C--152 to 203 centimeters; mottled yellowish brown (10YR 5/4), grayish brown (2.5Y 5/2), and dark reddish brown (5YR 3/4) stratified clay, loam, and sandy loam with thin lenses of silty clay loam; light yellowish brown (10YR 6/4), light gray (10YR 7/2), and brown (7.5YR 4/4) dry; massive; some horizontal and vertical angular planes of cleavage; firm, hard; neutral.

TYPE LOCATION: Otoe County, Nebraska; about 2 miles east and 1 mile south of Burr, Nebraska; 1,060 feet north and 60 feet west of the southeast corner of sec. 35, T. 7 N., R. 10 E.; USGS Burr topographic quadrangle; lat. 40 degrees 31 minutes 32.8 seconds N. and long. 96 degrees 15 minutes 21.0 seconds W., NAD 83.

RANGE IN CHARACTERISTICS: The mollic epipedon ranges from 25 to 56 centimeters thick. It includes the BA horizon and may include the upper part of the Bt horizon. Areas in native sod have an A1 horizon that ranges up to 15 inches thick. The particle size control section averages more than 5 percent sand.

The A horizon has hue of 10YR or 7.5YR, value of 2 or 3 and 3 to 5 dry, and chroma of 1 to 3. It is clay loam, loam, silt loam, or silty clay loam, but clay is allowed in places where the soil is eroded. Reaction is moderately acid or slightly acid.

The BA horizon has hue of 7.5YR or 10YR, value of 2 to 4 and 3 to 5 dry, and chroma of 2 to 4. In places the BA horizon is absent. Reaction is moderately acid or slightly acid.

The upper Bt horizon has hue of 7.5YR or 5YR, value of 3 to 5 and 4 to 6 dry, and chroma of 2 to 4 and 3 to 6 dry. Redoximorphic features range from faint to prominent. Organic stains and coatings are on the faces of peds with the uncrushed faces of peds being one value darker and one chroma higher than the ped interiors. The Bt1 horizon averages between 40 and 50 percent clay. It is typically clay, but in places it is sandy clay. Reaction is moderately acid through neutral.

The lower Bt horizon has hue of 5YR to 10YR, value of 4 or 5 and 5 or 6 dry, and chroma of 2 to 6. It is typically clay, but includes sandy clay. Reaction is slightly acid through slightly alkaline.

The BC horizon has hue of 2.5Y, 10YR, or 7.5YR, value of 4 or 5 and 5 to 7 dry and chroma of 2 to 6. It is clay or clay loam. Thin strata of dissimilar material ranging from silty clay loam to sandy loam are in the BC horizon of some pedons, but generally in the lower part. Reaction is slightly acid throughou moderately alkaline.

The C horizon has hue of 2.5Y, 10YR, or 7.5YR, value of 4 to 6 and 5 to 7 dry, and chroma of 2 to 6. Texture includes stratified clay, clay loam, silty clay loam, loam, or sandy loam. It is dominantly clay loam with an average clay content of 30 to 40 percent. Reaction is slightly acid through moderately alkaline.

COMPETING SERIES: These are the Arisburg, Arispe, Chase, Flanagan, Grundy, Herrick, Ipava, Lagonda, Lamoni, Martin, Pawnee, Rutland, Seymore, Shorewood, Tina and Wymore series. These soils have 10YR or yellower hue in the particle size control section. Chase, Martin, and Tina soils have a mollic epipedon more than 22 inches thick. Arisburg, Flanagan, Grundy, Herrick, Ipava Rutland Seymore and Wymore soils average less than 5 percent sand in the particle size control section.

GEOGRAPHIC SETTING: Mayberry soils are on convex summits and side slopes typically on areas adjacent to streams. Slope gradients range from 2 to 15 percent. The soil formed in material reworked from weathered Kansan till. The mean annual precipitation ranges from 28 to 34 inches, and the mean annual air temperature ranges from 51 to 56 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Pawnee and Wymore soils and the Malcolm and Morrill soils. Pawnee soils are usually on higher topographic positions in the landscape. Wymore soils formed in loess and are above Mayberry soils in the landscape. Malcolm soils formed in grayish silts. The Morrill soils are on similar positions but have a fine-loamy control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. Runoff is medium or rapid. Saturated hydraulic conductivity is low or very low. A perched water table is commonly at a depth of 1 to 3 feet in the spring.

USE AND VEGETATION: Most of the acreage is used to grow wheat, grain sorghum, and introduced grasses. A smaller acreage is in native vegetation, mostly big and little bluestem, switchgrass, and some forbs.

DISTRIBUTION AND EXTENT: Southeast Nebraska, northeast Kansas and possibly adjacent Iowa. The Mayberry series is of moderate extent.

SERIES ESTABLISHED: Pawnee County, Nebraska, 1969.

REMARKS: Diagnostic horizons and other features recognized in this pedon are: mollic epipedon--the zone from 0 to 25 centimeters (Ap and BA horizons); argillic horizon--the zone from 25 to 109 centimeters (Bt1 and Bt2 horizons); aquic conditions--saturation and redox features at depths less than 40 cm; vertic characteristics--clay content greater than 35 percent; estimate linear extensibility to be 6.0 cm or more in upper 100 cm; and udic moisture regime. Classification changed from fine montmorillonitic, mesic Aquic Argiudolls due to changes in Soil Taxonomy, 1992.
