Description of soil ONSCA~~~~~N (SCARP)

Orthic Regosol

The soil is in native condition (undisturbed by agriculture).

The soil material is primarily composed of mineral particles.

The water table is present in the soil during an unspecified period.

The growth of plant roots is not restricted by any soil layer.

Not Applicable

Water is removed from the soil readily but not rapidly. Excess water flows downward readily into underlying pervious material or laterally as subsurface flow. Soils have intermediate available water storage capacity (4-5 cm) within the control section, and are generally intermediate in texture and depth. Water source is precipitation. On slopes subsurface flow may occur for short durations, but additions are equaled by losses.

A sequence of more than three types of genetic mineral materials outcropping on a steep erosional escarpment. This complex class is to be used where units relating to individual genetic materials cannot be delimited separately at the scale of mapping. It may include colluvium derived from the various genetic materials and resting upon the scarp slope.

Moderately Fine (USDA Texture Classes: SCL,FSCL,VFSCL,CL,SICL,GSCL,GL,CBCL).

pH < 5.6
