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.
