NSSH Amendment 5

September 1999

This is a summary of major changes made to the NSSH with this amendment. The official copy of the NSSH is the web version. These changes have been incorporated into that version.

1. Part 601.01

  • (c) Add to the responsibilities of the state soil scientist the following:
    -- supplementing and distributing a state subset of the national soil information system data.
    -- providing to the responsible MLRA Office, layers desired for map finishing in a compiled or electronic format compatible with digital map finishing. These include such layers as hydrography, public land survey, roads, and recommended cultural features to be used in the survey.
  • (d) Add to the responsibility of the MLRA office:
    -- coordinating and providing quality assurance for the map finishing process which may involve doing the job, or coordinating with a state, digital map finishing center, or other entity that does map finishing,
  • Add part (e) and (f):
    (e) NCSS Responsibilities for the Digitizing Units
    -- digitizing compiled map materials, and
    -- performing quality control of final digital data including spatial, tabular, and metadata.
    (f) NCSS Responsibilities of the Digital Map Finishing Centers
    -- electronically preparing soil survey maps for publication.
  • (g) Add to the responsibilities of NGDC:
    -- providing the process, procedures, and the training to generate map finished products,

2. Part 606.02 (f)

  • Add as the 2nd paragraph the following:
    -- Indicate whether or not small areas of contrasting soils or miscellaneous areas will be shown on the maps using point and/or line features. This will generally involve mapping such areas at a higher level of detail than the majority of the survey area. Such areas will be identified with map unit symbols and are included in the legend for the survey area.

3. Part 606.03 (b)

  • Revise to read:
    For maintenance of soil areas that have been previously published, the memorandum of understanding is to include the MLRA project plan and evaluations of all the soil surveys. Send these materials to the National Soil Survey Center with a letter requesting the Director, Soil Survey Division, to approve.

4. Exhibit 606-1 Memorandum of Understanding for a soil survey area.

  • Change the 1st paragraph under Specifications to read:
    Map units will be consociations and complexes of phases of soil series. The maximum size of contrasting inclusions in arable map units will be 5 acre areas. If needed by local users, contrasting inclusions of less than 5 acre areas may be shown by use of conventional or special symbols or mapped as point or line segments approved by the MLRA office. The maximum size of contrasting inclusions in nonarable map units will be 10 acre areas. The soils in each delineation will be identified by direct field examination. Systematic traverses will be made in arable map units at an interval close enough to detect 5 acre areas that require significantly different management, and in nonarable map units close enough to detect 10 acre areas.
  • Change the 4th paragraph to read:
    Field notes will be taken on soil qualities, soil properties, and soil performance to support soil interpretations for cropland, pastureland, windbreaks, rangeland, wildlife habitat, riparian area management, irrigation, rural and community development, recreation, engineering properties, and such groups as hydric soils, highly erodible lands, sodic soils, saline soils, sodic-saline soils, and other soils requiring special management.

  • Also revise the 9th included item to read as follows:
    -- a letter transmitting the report, in which the MLRA Leader highlights significant issues and items that are agreed upon; and

9. Part 608.11(b)(3) Final Field Reviews., (iii) Preparation of the Report.

  • Revise to read as:
    The leader of the final field review prepares a report of the review. The report includes a "Quality Assurance Worksheet" that has been approved by the MLRA Office. Exhibit 608-7 is an example. In addition to the Quality Assurance Worksheet, the report includes:

10. Part 608.11(c) Signature and Approval of Field Review Reports., (2)Representatives of cooperating agencies.

16. Part 617.01

  • Add as d, e, f the following:
    (d) The Memorandum of Understanding states which interpretations will be made for a soil survey area. The MLRA office, state soil scientist, and cooperators agree on whether or not to generate interpretations for miscellaneous land types and minor soil components. The Soil Survey Division encourages the entry of data and preparation of soil interpretations for miscellaneous areas. Omission of data elements is by joint consensus of the MLRA office, state soil scientist, and cooperators.
    (e) Completely populate the data elements that are used as criteria in an interpretation in order to generate reliable interpretations.
    (f) Completely populate the data elements for major soil components including map unit components classified as higher taxonomic categories. The MLRA office, state soil scientist, and cooperators should reach a joint decision for special situations where it is not practical to populate data elements for map unit components classified at a higher taxonomic category than soil series. If the range of properties is too wide for interpretations, these areas may not meet the requirements of the user defined needs of the survey.
