Guides for Editing Soil Properties
Soil properties are measured from direct observations in the field or laboratory. Examples are bulk density, particle size distribution, cation exchange capacity, soil moisture status, and organic matter.
Guides for Editing Soil Interpretations and Qualities
Soil interpretations/qualities are behavior and performance attributes of the soil that cannot be directly measured. They are developed from observations of dynamic conditions and from soil properties. Examples are soil drainage class, AASHTO, corrosivity, frost action, and wind erodibility.
