  1. MODULE 3Review of Components and Map Units From basic soil survey and pre-course reading; NSSH 627

  2. Break into groups • Each group will compete as a team. • The team will select a category and point value. • Team will provide answer. If answer is wrong the team looses the points and another team can pick up the points. Please have a complete answer . • Winning team gets a prize.

  4. Where can a list of approved miscellaneous areas be found?

  5. National Soil Survey Handbook (most current)Soil Survey Manual

  6. Several soil survey legends have a Variant as a component name. When is it most appropriate to use a Variant?

  7. NEVER; use of Variants became obsolete in 1988.

  8. A taxadjunct is named after an existing series. What are the other criteria for use of a taxadjunct?

  9. Classifies outside the taxonomic class limits of the named series.Response to use and management is similar to the named series.

  10. There are five kinds of components, name them.

  11. *Soil series*Taxonomic categories above the series*Taxadjunct*Miscellaneous area*Phases of components

  12. Which one or more of the following are valid miscellaneous areas?Badland, Chutes, Dams, Dunes, Eroded, Rubbleland, Water

  13. BadlandChutesWaterDamsDunes is not approved, but Dune land is.Rubbleland is not approved, but Rubble land is.Eroded is not approved, could be a phase of a component.

  14. Name the four kinds of map units

  15. AssociationComplexConsociationUndifferentiated Group

  16. What is the distinguishing difference between a complex and an association?

  17. The ability to delineate or not delineate the major components at the scale of mapping.Complex can not delineate.Association could delineate.

  18. A minor limiting map unit component should be considered a major component when its percent composition exceeds what percent?

  19. 10 percent

  20. A map unit can consist of a collection of what three kinds of delineations?

  21. *A collection of polygons. *A collection of points.*A collection of lines.

  22. Dissimilar map unit components can account for what percent of the map unit?AND What percent is limiting and what percent is non-limiting?

  23. Total dissimilar minor components 40 percent.Dissimilar limiting total 15 percent. Dissimilar non-limiting 25 percent.

  24. Which one or more of the following are NOT a valid NASIS component name data field entry?BetaUnnamedPoorly drained soilsHapludollsRock outcrop, sandstoneBeta soils on steeper slopesLoamy alluvial land

  25. Poorly drained soilsBeta soils on steeper slopesLoamy alluvial landRock outcrop, sandstoneUnnamed

  26. Given the following 5 phase terms, provide the most appropriate map unit name.Beta2 to 5 percent slopessalinesilt loamvery stony

  27. Beta silt loam, saline, 2 to 5 percent slopes, very stony
