Montana Soil Survey Technical Guides

• Guides for Editing Soil Properties
  Soil properties are measured from direct observations in the field or laboratory. Examples of soil properties are bulk density, cation-exchange capacity, organic matter, particle-size distribution, and soil moisture status.
  
• 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 of soil interpretations/qualities are AASHTO, corrosion, drainage class, frost action, and wind erodibility.
• Other Local Guides for Montana
  Local guides provide instructions for Soil Scientists in Montana. Examples of other local guides are ArcGIS instructions, denied access--projecting lines, guide for 1N HCl, hydric soils criteria, and quick SAR test.
  
• Guides for Determining Which Soil Properties Are Used to Generate an Interpretation
  The NASIS Interpretations Generator uses Soil Properties to generate custom interpretations using local criteria. This document provides instructions to determine the specific soil properties used to generate any interpretation.
