Hepler soil series

A representative soil profile of the Hepler soil series. (Soil Survey of Jasper County, Missouri; by Alan C. Peer, Natural Resources Conservation Service)

 

The Hepler series consists of very deep, somewhat poorly drained soils that formed in silty alluvial sediments. These nearly level to very gently sloping soils are on flood plains in the Cherokee Prairies (MLRA 112) and Ozark Highlands (MLRA 116A). Slope ranges from 0 to 3 percent. Mean annual precipitation is about 1067 mm (42 inches), and mean annual temperature is about 14 degrees C (58 degrees F).

 

TAXONOMIC CLASS: Fine-silty, mixed, superactive, thermic Mollic Endoaqualfs

 

Depth to argillic horizon: 41 to 76 cm (16 to 30 inches)

Depth to redox concentrations: 10 to 30 cm (4 to 12 inches)

Depth to endosaturation: 30 to 201 cm (12 to 79 inches) from January to May.

Particle-size control section: (weighted average) 18 to 35 percent clay, 4 to 15 percent sand

 

Ap or A horizon:

Hue: 10YR

Value: 2 or 3, 3 to 4 dry

Chroma: 1 or 2

Texture: silt loam

Clay content: 9 to 27 percent

Base saturation: 59 to 79 percent

Reaction: Neutral to strongly acid

 

USE AND VEGETATION: Mostly cultivated. Principal crops are winter wheat, soybeans, grain sorghum, and corn. Native vegetation is hardwood forest with an understory of tall prairie grasses.

 

DISTRIBUTION AND EXTENT: MLRAs 112 and 116 in southeastern Kansas, southwestern Missouri and eastern Oklahoma. The type location is in MLRA 112. The series is of moderate extent.
