SOIL INTERPRETATIONS
Footnotes:
i
Texture of Control Section: as defined in Soil Taxonomy (Soil Survey Staff 1999). The textural control section is generally the upper 20 inches or the whole of an argillic horizon; or
from 10-40" or
bedrock, whichever is shallower; or the entire soil profile if bedrock is 14" deep or less.
2
Depth: refers to the soil profile depth before encountering bedrock or a paralithic contact.
Depth Class Inches
Very Shallow <10
Shallow 10-20
Moderately Deep 20-40
Deep 40-60
Very Deep >60
3
Effective Rooting Depth: The part of the soil that can be penetrated by plant roots.
4
Internal Drainaee: refers to aeration or saturation characteristics within the soil profile. Well drained soils allow water to move through the profile readily but not rapidly, and soil
aeration is typically
not a problem. Somewhat excessively drained soils allow water to move rapidly through the profile, and are typically droughty, sandy, and poorly developed. Somewhat poorly drained soils
have a wet
state relatively high in the profile for a significant length of time to impede most uses, unless artificially drained.
s
Permeability: Permeability is a characteristic of soil which relates to the movement of water through the profile. Permeability criteria are based on the rate at which water moves through
the most
slowly permeable layer to a depth of 60 inches in a saturated soil profile.

Available Water Holding Capacity: the relative amount of water that a soil, from 0 to 60 inches, or to a paralithic or lithic contact, can hold available for use by plants, affected
by such characteristics as
soil texture, depth, structure, salts, and organic matter. AWHC modifiers are site-specific for the sampled soil profiles. Classes are: Low = <6 inches; Moderate = 6-9 inches; High =
>9 inches. (Soil
Survey Staff 1993).
7
Rate of Runoff This indicates the relative rate that water is removed by flow over the surface of the soil. Classes are defined in the Soil Survey Manual (Soil Survey Staff 1993).
