MUNJOR SERIES

The Munjor series consists of deep well drained or moderately well drained soils that formed in loamy alluvium. These soils are on flood plains or terraces and have slopes that range from 0 to 3 percent. Mean annual temperature is 12 degrees C. (54 degrees F.), and mean annual precipitation is 58 centimeters (23 inches) at the type location.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, calcareous, mesic Typic Ustifluvents

TYPICAL PEDON: Munjor sandy loam in a native grass field. (Colors are for dry soil unless otherwise stated.)

A--0 to 18 centimeters (0 to 7 inches); grayish brown (10YR 5/2) sandy loam, dark grayish brown (10YR 4/2) moist; weak medium granular structure; soft, very friable; few fine and medium roots; slight effervescence; moderately alkaline; gradual smooth boundary. (8 to 38 centimeters (3 to 15 inches) thick)

2C--18 to 112 centimeters (7 to 44 inches); light brownish gray (10YR 6/2) sandy loam, grayish brown (10YR 5/2) moist; weak medium granular structure in upper part and massive in lower part; soft, very friable; thin stratified layers of finer-textured and coarser-textured materials are throughout the horizon; strong effervescence; moderately alkaline; gradual smooth boundary. (38 to 127 centimeters (15 to 50 inches) thick)

2C--112 to 152 centimeters (44 to 60 inches); pale brown (10YR 6/3) sand, brown (10YR 5/3) moist; single grained; loose; strong effervescence; moderately alkaline.

TYPE LOCATION: Ellis County, Kansas; about 14 kilometers (9 miles) south and 2 kilometers (1 1/2 miles) east of Victoria, Kansas; 701 meters (2300 feet) west and 366 meters (1200 feet) north of the southeast corner, sec. 29, T. 15 S., R. 16 W.

RANGE IN CHARACTERISTICS:
Depth to free carbonates: 0 to 25 centimeters (0 to 10 inches)
Reaction: moderately alkaline throughout
Sand: below 76 centimeters (30 inches) in most pedons

A horizon:
Hue: 10YR
Value: 5 to 7, 3 to 5 moist
Chroma: 1 to 3
Upper part A1 horizon in some pedons: color value darker than 5.5 dry and 3.5 moist but is less than 18 centimeters (7 inches) thick
Texture: sandy loam, loamy sand, loamy fine sand, fine sandy loam, and loam
AC horizon: in some pedons

C horizon:
Hue: 10YR
Value: 5 to 7, 4 to 6 moist
Chroma: 2 or 3
Texture: loamy very fine sand, sandy loam, fine sandy loam, or loam
Thin strata: of coarser or finer material in mnay pedons
Buried soils: color value 5 dry and 3 moist in a few pedons

2C horizon:
Hue: 10YR
Value: 6 or 7, 5 or 6 moist
Chroma: 2 to 4
Texture: loamy sand, fine sand, or sand
Gravel: 1 to 3 percent gravel in some pedons
Faint mottles: below depths of 51 centimeters (20 inches) in some pedons
Distinct mottles: below 76 centimeters (30 inches)
2C horizon: lacking in some pedons

COMPETING SERIES: These are the Flatnose, Peralta and Pietown series.
Flatnose soils are drier in the late spring and summer and have lower annual precipitation.
Peralta soils have distinct mottles within 76 centimeters (30 inches) and saturation at 61 to 91 centimeters (24 to 36 inches) March to October
Pietown soils are dryer during May and June.

GEOGRAPHIC SETTING:
Landform: low terraces or flood plains
Slope: 0 to 2 percent
Parent material: loamy alluvium
Mean annual temperature: 8 to 14 degrees C. (47 to 57 degrees F.)
Mean annual precipitation: 41 to 66 centimeters (16 to 26 inches)
Thornthwaite annual P-E index: 30 to 40

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gibbon, Inavale, McCook, and Roxbury soils.
Gibbon soils contain less sand, are more poorly drained, and are on slightly lower positions.
Inavale and McCook are on similar positions as Munjor soils.
Inavale soils contain more sand, and McCook soils are coarse-silty.
Roxbury soils are on slightly higher positions and contain more clay and less sand and have a mollic epipedon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained or moderately well drained
Runoff: low
Saturated Hydraulic Conductivity: high
Water table: below 1.8 meters (6 feet) except during short periods of high stream flow

USE AND VEGETATION: Most areas of Munjor soils are cultivated.
Grain sorghums, winter wheat, and alfalfa are the main crops.
Native vegetation is mixed grass prairie.

DISTRIBUTION AND EXTENT: North-central Kansas, adjacent areas of Nebraska, and south- central South Dakota. The series is of moderate extent.

MLRA OFFICE RESPONSIBLE: Salina, Kansas

SERIES ESTABLISHED: Harlan County, Nebraska, 1970.

REMARKS: Diagnostic horizons and features recognized in this pedon are:

Modified format by LRM in 8/2006 to include metric conversion and change permeability to saturated hydraulic conductivity.
