  1. Assemble, Summarize, and Review Historical Data

  2. Rationale Before an evaluation can begin, the user must assemble all the various historical products and tools. This module is designed to put forth ideas on the products and tools that should be reviewed

  3. Lesson Objectives • Determine the various type of data that exist for the evaluation • Identify historical data to be assembled • Identify tools that are available • Identify data to be summarized

  4. What information should be collected before proceeding with the MLRA evaluation? • Use the Chat room to begin a list

  5. Data to be Assembled 610.03c • map unit descriptions • unpublished soil information • records documenting soil survey joining problems • interpretations • correlation records • field review reports • special investigation and laboratory data • pedon descriptions • transect data • tacit knowledge of those experienced in the area • notes of needed changes recorded in the office copy of the published soil

  6. How Many Non-MLRA Soil Survey Areas Are In Your Area of Responsibility? MLRA 105 Crosses Into 35 Unique Non-MLRA Soil Survey Areas.

  7. What Are The Publication Dates?

  8. THE ORIGINAL SOIL SURVEY REPORTS WILL PROVIDE IMPORTANT INFORMATION

  9. Some survey areas have two or three publications!

  10. SOIL SURVEY REPORT • Map Unit Descriptions (Concept) • Composition • Dates of Field Work • Project Members • Georeferenced Series Descriptions (TUDS) • Dual Drainage Class? • 3SD Overrides? • Layer Thickness

  11. What Are The Correlation Dates?

  12. Each MLRA should have copies of the correlation documents available in their area.

  13. The Correlation Document Provides • Who (Who did the mapping) • When It Occurred • How many components (series and phases) • Notes to Accompany Series

  14. The MLRA Explorer Snap Shot www.cei.psu.edu/mlra/

  15. The MLRA Explorer Snap Shot

  16. The MLRA Explorer Snap Shot

  17. How many components (series) are mapped in your MLRA area?

  18. 334 Series in 105 by OSD site

  19. Series Description or Extent Map?

  20. What about NASIS?

  21. NASIS Reports

  22. What about the SSURGO template?

  23. Paste NASIS/SSURGO list into OSD

  24. Things you learn using NASIS data The query pulled those components listed as a ”series”. MLRA 105 has some database work to complete

  25. When Were the Series Established? Revised? • SERIES ESTABLISHED: Cass County, Illinois, 1939. • LOCATION ARENZVILLE WI+IA IL MN Established SeriesRev. AJK-HFG-TWN09/2006

  26. NASIS Reports

  27. NASIS Reports

  28. Imagery 1939 • 1976 1985 2006

  29. Multiple Year Imagery Sets Provide • Land Use Changes • Hydric Signatures • Flooding Signatures • Erosion? • Siltation? • Other?

  30. What other types of data? • Farm and Ranch Plan Mapping • STATSGO • Geological Survey? • FEMA Maps? • Other?

  31. Other Historical Resources • Maybe There’s a (Re)Tired Soil Scientist Around • University Cooperators • Masters Thesis or PhD Dissertations • What can the Field Office Staff Tell You? • Crop Consultants and Extension Agronomists • Foresters and Other Land Managers

  32. Your GIS Workstation • Utilize digital layers of your MLRA • What Layers Are Available? • How Many SSA’s? • Distribution Maps

  33. NCGC developed MLRA-SSO Geodatabases contain: • Detailed SSURGO Maps • 30m Digital Elevation Models • National Hydrography Layer • web map services NAIP (http://gis1.ftw.nrcs.usda.gov/arcgis/services)SSURGO (http://sdmdataaccess.nrcs.usda.gov/Spatial/SDM.wms?)

  34. Distribution and Extent Maps Distribution map of fine-silty…typic hapludalfs in MLRA 105

  35. Arenzville map units distribution

  36. Where is the Series Mapped? The Arenzville Series extends beyond MLRA 105. There is a gap in survey areas where Arenzville was not mapped.

  37. Series Extent acres report

  38. Is there lab data available? Using Advanced Query by MLRA from Characterization web site Returns 265 pedons sampled in 105

  39. Is there lab data available? Grab the NSSL access database by MO from lab sharepoint site

  40. Suggested Activity • Develop an MLRA “Thunderbook” for your MLRA and list: • All manuscripts and their publication dates • Soil Survey Areas and correlation dates • Unique map unit names and total acreages • Unique components and their OSDs • Component acreage by survey area and totals • Correlation reports for the survey areas • NSSL samples

  41. You are just getting started • One you’ve developed a good inventory, you’ll be able to examine: • individual components and phases • data map units • common resource areas • watersheds • dissimilar inclusions • landforms • properties • interpretations
