LOCATION HODGE MOEstablished Series
TAXONOMIC CLASS: Mixed, mesic Typic Udipsamments
TYPICAL PEDON: Hodge loamy fine sand - on a 1 percent convex east-facing slope in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 7 inches; dark brown (10YR 3/3) loamy fine sand, grayish brown (10YR 5/2) dry; single grain; loose; slight effervescence; mildly alkaline; abrupt smooth boundary. (3 to 10 inches thick)
C1--7 to 20 inches; brown (10YR 5/3) fine sand thinly stratified with lenses of loamy fine sand; single grain; loose; slight effervescence; mildly alkaline; abrupt smooth boundary. (0 to 20 inches thick)
C2--20 to 24 inches; thinly stratified dark grayish brown (10YR 4/2) very fine sandy loam and loamy fine sand; massive; friable; common fine prominent yellowish red (5YR 4/6) stains along root channels and lenses; slight effervescence; mildly alkaline; abrupt smooth boundary. (0 to 30 inches thick)
C3--24 to 27 inches; brown (10YR 5/3) loamy fine sand thinly stratified with lenses of fine sand; single grain; loose; common fine prominent yellowish red (5YR 4/6) stains along root channels and lenses; slight effervescence; mildly alkaline; clear smooth boundary. (0 to 12 inches thick)
C4--27 to 60 inches; grayish brown (10YR 5/2) fine sand with strata of loamy fine sand; single grain; loose; strong effervescence; mildly alkaline.
TYPE LOCATION: St. Charles County, Missouri; 850 feet south and 4,550 feet east of the northwest corner of Spanish survey 1643, T. 45 N., R. 2 W.; UTM coordinates 693,510m E., and 4,274,600m N.
RANGE IN CHARACTERISTICS: Reaction is mildly alkaline or neutral throughout the soil. The 10- to 40-inch control section is commonly calcareous in some parts and averages more than 10 percent silt plus clay. Silt plus clay plus very fine sand totals 40 percent or more. Most pedons contain less than 10 percent medium sand or coarser.
The Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Noncultivated areas have A1 horizons 1 to 6 inches thick with colors similar to those stated for the Ap horizon. The A horizon typically is fine sand or loamy fine sandy but some pedons are fine sandy loam.
The C horizon has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. It typically is loamy fine sand or fine sand but many pedons have thin (less than 1 cm. thick) layers or lenses of finer texture.
COMPETING SERIES These are the Abscota, Carver, Chute, Dabney, Oakville, Penwood, Perks, Plainfield, Sarpy, Suncook, Tyner, Westport, and Windsor series. Abscota soils contain less than 10 percent silt plus clay and have less fine and very fine sand. Carver, Dabney, Oakville, Penwood, Perks, Plainfield, Suncook, Tyner, Westport, and Windsor soils lack free carbonates in the 10- to 40-inch control section. Chute soils lack stratification within the control section. Sarpy soils have less than 10 percent silt plus clay and less than 40 percent silt plus clay plus very fine sand in their 10-to 40-inch control section.
GEOGRAPHIC SETTING: Hodge soils are on undulating flood plains. Slope gradients dominantly are less than 2 percent but range to 5 percent in some pedons. Hodge soils formed in sandy alluvium. The mean annual temperature varies from 52 to 57 degrees F, and mean annual precipitation varies from 35 to 44 inches.
GEOGRAPHICALY ASSOCIATED SOILS: These are the Aholt, Albaton, Bosworth, Gilliam, Haynie, Kenmoor, Leta, Modale, Sarpy, Waldron, and Waubonsie soils. The Aholt, Albaton, Bosworth, Gilliam, Haynie, Kenmoor, Leta, Modale, Waldron, and Waubonsie soils contain more clay and are on adjacent flood plains. Sarpy soils contain less silt and clay and occur on similar landscapes.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained. Runoff is slow. Permeability is rapid. Hodge soils are frequently flooded where not protected by levees.
USE AND VEGETATION: Soils are cropped to corn, wheat, and soybeans; and some areas are used for hay. Native vegetation is mostly cottonwood and oak trees with some interspersed tall grasses.
DISTRIBUTION AND EXTENT: Along the Missouri River in Missouri. The extent is moderate.

SERIES ESTABLISHED: Lafayette County, Missouri, 1970.
REMARKS: The finer textured layers are stratification and do not exhibit properties of argillic horizon development.
