Grant soil series

A representative soil profile of the Grant soil series. (Soil Survey of Woods County, Oklahoma; by Richard Gelnar, Jimmy Ford, Clay Salisbury, Clay Wilson, and Glen Williams, Natural Resources Conservation Service)

 

The Grant series consist of deep, well drained, moderately permeable soils. They formed in material weathered predominantly from siltstone or silty shale of Permian age. These nearly level to moderately steep soils are on treads and risers of paleoterraces in the Central Rolling Red Prairies (MLRA 80A). Slope ranges from 0 to 20 percent. Mean annual precipitation is 813 mm (32 in) and mean annual air temperature is 16 degrees C (61 degrees F).

 

TAXONOMIC CLASS: Fine-silty, mixed, superactive, thermic Udic Argiustolls

 

Depth to paralithic contact: 102 to 152 cm (40 to 60 in) to siltstone or silty shale

Depth to secondary carbonates: 76 to 152 cm (30 to 60 in)

Particle-size control section:

Clay content: 18 to 35 percent

Sand content: 0 to 15 percent

 

USE AND VEGETATION: Used for cropland. Some areas are in native grassland. Cultivated crops are wheat and other small grains. Native vegetation is tall and mid grasses.

 

DISTRIBUTION AND EXTENT:

General area: Oklahoma and south-central Kansas

Land Resource Region: H-Central Great Plains Winter Wheat and Range

MLRA 80A-Central Rolling Red Prairies
