Oregon's State Soil!

INTRODUCING THE JORY SOIL! 

The Oregon state soil is called Jory. The Jory soil series consists of very deep, well-drained soils that formed in colluvium (unconsolidated sediments that have been deposited at the base of hillslopes by either rain wash, sheet wash, and slow continuous downslope creep). The sediments are weathered and eroded from basaltic igneous rock. These soils are in the foothills surrounding the Willamette Valley.

Jory soils generally support forest vegetation, dominantly Douglas fir and Oregon white oak. They are very productive forest soils. Many areas have been cleared and are used for agricultural crops including: Christmas trees, various berries, hazelnuts, sweet corn, wheat, and many varieties of grass seed.

The Soil Profile is described as:
Surface layer (duff): organic material 
Top Soil layer: dark reddish brown silty clay loam 
Subsoil - upper: dark reddish brown clay 
Subsoil - lower: red clay.
