NRS 450 EXAM 2 QUESTIONS COMPLETE
WITH 100% VERIFIED ANSWERS
\.Why do we use soil surveys? - ANSWERS✔-Study of the soil of an area
• Mapping
• Classification
• Distribution
• Identify soils withsimilar properties
• Land use interpretations
\.Taxonomic Soil Survey - ANSWERS✔-Descriptive
• Soils' natural properties
• Ex: RI Soil Survey
\.Interpretive Soil Survey - ANSWERS✔-Based on taxonomic map
•One purpose/interpretation
• Ex: Suitability/limitations for use
\.Ancient Soil Survey - ANSWERS✔-5000-6000 years old
\.Old Soil Survey - ANSWERS✔-Prior to 1930s
,Cartographers and soil scientists walk/map
\.Pre Modern Soil Survey - ANSWERS✔-Early 1950s
\.Modern Digital Soil Survey - ANSWERS✔-Available Online
Web Soil Survey
SoilWeb
\.Inclusions on Soil Surveys - ANSWERS✔-Similar soils:
Same classifications
Same interpretations
Dissimilar soils:
Different classifications
Different interpretations
\.Consociations - ANSWERS✔-At least 50% of soils are one name and <25% of soils
are dissimilar inclusions
\.Complexes - ANSWERS✔-2 or more soil names that occur in a regularly repeating
patter and <25% of soils are dissimilar inclusions
Major components cannot be mapped out/distinguished due to scale
\.Associations - ANSWERS✔-Broad Units
, General units used to provide broad look at landscape soils
\.Undifferentiated groups - ANSWERS✔-2 or more soils names; do not always
occur together in the same map delineation
Similar soils; could map them out, but we DONT
\.Miscellaneous areas - ANSWERS✔-NOT SOIL (gravel pits, mining areas)
\.Map Unit Phases - ANSWERS✔-Additional component added on to a map unit
Describes what the landscape is like
(stoniness, slope, surface, texture, etc.)
"0 to 8 percent slopes, extremely stony"
\.What are some Soil Survey limitations? - ANSWERS✔-Scale (time, accuracy)
Conceptual nature (narrow, broad)
Individual biases
Compilation
Map unit accuracy
\.How do we work around limitations? - ANSWERS✔-Evaluate and reading
between the lines?
\.Why do we classify soils? - ANSWERS✔-Organize information
