NOWATA SERIES

The Nowata series consist of moderately deep, well drained soils that formed in loamy material weathered from cherty limestone of Pennsylvanian age. These very gently sloping to sloping soils are on slightly convex side slopes of uplands in the Cherokee Prairies. Slope ranges from 2 to 7 percent. Mean annual precipitation is about 1041 mm (41 inches), and mean annual temperature is about 15.5 degrees C (60 degrees F).

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, thermic Typic Argiudolls

TYPICAL PEDON: Nowata silt loam -in grassland on shoulder of an interfluve, at an elevation of 237 meters (778 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

A--0 to 31 cm (0 to 12 inches); dark brown (7.5YR 3/2) silt loam, brown (7.5YR 5/2) dry; moderate medium granular structure; hard, friable; 5 percent by volume rounded fragments of chert less than 76 mm (3 inches) in diameter; slightly acid; gradual smooth boundary. [20 to 36 cm (8 to 14 inches) thick]

BA--31 to 46 cm (12 to 18 inches); brown (7.5YR 4/2) gravelly silt loam; weak medium subangular blocky parting to moderate medium granular structure; hard, friable; 15 percent by volume rounded chert gravel less than 76 mm (3 inches) in diameter, slightly acid; gradual smooth boundary. [8 to 23 cm (3 to 9 inches) thick]

Bt1--46 to 74 cm (18 to 29 inches); reddish brown (5YR 4/3) extremely gravelly silty clay loam, moderate medium subangular blocky structure; very hard, firm; clay films on surfaces of peds and in pores; 70 percent by volume rounded chert gravel less than 76 mm (3 inches) in diameter; slightly acid; gradual wavy boundary. [20 to 43 cm (8 to 17 inches) thick]

Bt2--74 to 91 cm (29 to 36 inches); reddish brown (5YR 4/4) extremely gravelly silty clay loam, weak fine subangular blocky structure; very hard, firm; clay films on surfaces of peds and in pores; 70 percent by volume rounded chert gravels less than 76 mm (3 inches) in diameter; neutral, abrupt wavy boundary. [0 to 28 cm (0 to 11 inches) thick]

R--91 to 97 cm (36to 38 inches); hard limestone bedrock.

COMPETING SERIES: There are no other soils in the same family. Soils in similar families are the Caspiana, Catoosa, Claremore, Clareson, Eldorado, Fitzhugh, Lula, Mason, Mer Rouge, Newtonia, Scullin and Tiptonville series. Caspiana, Eldorado, Fitzhugh, Lula, Mason, Mer Rouge, Newtonia, and Tiptonville soils are deeper than 102 cm (40 inches). Claremore soils are shallower than 51 cm (20 inches). Catoosa soils have a fine-silty control section, and Scullin soils have a fine control section. Clareson soils have a clayey-skeletal control section.

GEOGRAPHIC SETTING: Nowata soils are on slightly convex side slopes of uplands in the Cherokee Prairies. Slope ranges from 2 to 7 percent. These soils formed in material weathered from hard cherty limestone that is jointed of Pennsylvanian age. Climate is moist subhumid to humid. Mean annual precipitation ranges from 965 to 1143 mm (38 to 45 inches). Mean annual temperature ranges from 13.8 to 18 degrees C (57 degrees to 64 degrees F). Elevation is 260 to 340 meters (853 to 1115 feet) above mean sea level. Thornthwaite P-E indices range from 64 to 80.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Claremore and Catoosa series on similar landscapes. Claremore soils are shallower than 51 cm (20 inches). Catoosa soils have a fine-silty control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. Potential for surface runoff is medium. Saturated hydraulic conductivity is moderately high. Permeability is moderately slow.

USE AND VEGETATION: Mostly in native grass consisting of big bluestem, little bluestem, switchgrass, and indiangrass.

DISTRIBUTION AND EXTENT: MLRA 112 in northeastern Oklahoma, southwestern Missouri and southeastern Kansas. The soil is moderately extensive.
