NEW CAMBRIA SERIES

The New Cambria series consists of deep moderately well drained soils. These soils formed in alluvium on stream terraces or flood plains in the Rolling Plains and Breaks, MLRA 73. Slopes range from 0 to 2 percent. Mean annual temperature is 12 degrees C (53 degrees F) and mean annual precipitation is 685 millimeters (27 inches).

TAXONOMIC CLASS: Fine, smectitic, mesic Cumulic Haplustolls

TYPICAL PEDON: New Cambria silty clay is in a cultivated field. (Colors are for dry soil unless otherwise stated.)

Ap--0 to 15 centimeters (0 to 6 inches); dark grayish brown (10YR 4/2) silty clay, very dark gray (10YR 3/1) moist; moderate fine granular and angular blocky structure; very hard, firm; slight effervescence; moderately alkaline; abrupt smooth boundary.

A--15 to 36 centimeters (6 to 14 inches); dark gray (10YR 4/1) silty clay, very dark brown (10YR 2/2) moist; strong fine granular and angular blocky structure; extremely hard, very firm; many fine roots and pores; few worm casts; slight effervescence; moderately alkaline; diffuse smooth boundary. (Combined thickness of the A horizon is 23 to 38 centimeters (9 to 15 inches) thick)

Bw1--36 to 64 centimeters (14 to 25 inches); dark gray (10YR 4/1) silty clay, very dark gray (10YR 3/1) moist; moderate medium and fine angular blocky structure; extremely hard, very firm; many fine roots and pores; slight effervescence; moderately alkaline; diffuse smooth boundary.

Bw2--64 to 81 centimeters (25 to 32 inches); dark gray (10YR 4/1) silty clay, very dark gray (10YR 3/1) moist; moderate medium angular blocky and subangular blocky structure; extremely hard, very firm; many fine roots and pores; few films and threads of calcium carbonate; slight effervescence; moderately alkaline; diffuse smooth boundary. (Combined thickness of the Bw horizon is 40 to 90 centimeters (16 to 35 inches) thick)

C1--81 to 109 centimeters (32 to 43 inches); gray (10YR 5/1) silty clay loam, dark gray (10YR 4/1) moist; structureless massive; very hard, firm; many very-fine pores; few fine roots; many films and threads of calcium carbonate; strong effervescence; moderately alkaline; gradual smooth boundary.

C2--109 to 200 centimeters (43 to 80 inches); light brownish gray (10YR 6/2) silty clay loam, dark grayish brown (10YR 4/2) moist; structureless massive; very hard, firm; many films and threads of calcium carbonate, many fine non-cemented calcium carbonate masses; strong effervescence; moderately alkaline.

COMPETING SERIES: This is the Shay series.
Shay soils are somewhat poorly drained and have an Aridic soil moisture regime.

GEOGRAPHIC SETTING:
Landform: stream terraces or floodplains
Slope: 0 to 2 percent
Parent material: alluvium
Mean annual air temperature: 10 to 13 degrees C (50 to 55 degrees F)
Mean annual precipitation: 560 to 760 millimeters (22 to 30 inches)
Thornthwaite annual P-E index: 36 to 54
Frost-free period: 160 to 210 days

GEOGRAPHICALLY ASSOCIATED SOILS:
These are Bogue, Detroit, Muir and Roxbury soils.
Bogue soils are on adjacent uplands and are underlain by clayey shales.
Detroit soils are on similar landforms and have an increase in illuvial clay in the particle size control section (an argillic horizon).
Muir and Roxbury soils are on similar landforms and have less than 35 percent clay in the particle size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: moderately well
Runoff: low
Saturated Hydraulic Conductivity: moderately low
Flooding: very rare to frequent.

USE AND VEGETATION: Most areas are cultivated.
Winter wheat and sorghum are the principal crops.
Native vegetation is mid and tall grasses.

DISTRIBUTION AND EXTENT: Central and north-central Kansas. LRR H Great Plains Winter Wheat and Range, MLRA 73 Rolling Plains and Breaks, MLRA 74 Central Kansas Sandstone Hills. The soils of this series are of moderate extent.

Added soil moisture regime, soil temperature regime, mean annual soil temperature, particle size clay and sand content. Added clay and sand content and reaction to horizon data in RIC. Added calcium carbonate equivalence to horizon data in RIC. Updated competing series. Updated geographic setting. Lowered mean annual air temperature to 10 to 13 degrees C from 12 to 14 degrees C based on climate data. Updated geographically associated soils. Added flooding frequency. Added additional data

ADDITIONAL DATA: Additional laboratory data-- National Soil Survey Laboratory, Lincoln, Nebraska pedons: 81KS123001.
