Non-Technical Summary

Statement of Issues and Justification

The National Cooperative Soil Survey (NCSS) includes federal, state, university and local partners with a public mandate for identification, inventory, use and management of soil resources. These partners include university pedologists from each agricultural experiment station (AES) in the nation; representatives from the USDA, Natural Resources Conservation Service (NRCS); USDI, Bureau of Land Management; USDA, Forest Service; Cooperative States Research, Education, and Extension Service (CSREES) and state and local agriculture and/or natural resource agencies. The NCR-3 committee is an essential component for coordinating National Cooperative Soil Survey (NCSS) activities in the North Central Region (NCR). The NCR-3 Committee members serve on a national advisory board to the NRCS. The board is charged with reviewing policies and making recommendations to improve procedures in the soil survey program, identifying and coordinating important soil and water research efforts, developing soil/water interpretive guidelines and related activities.

The NCSS is placing more emphasis on improving the scientific basis and extrapolative utility of soil interpretations, and development of improved systems for storage, retrieval, analysis, and display/dissemination of SSI, and procedures for increasingly complex and invasive land use practices. These areas of emphasis draw heavily on the scientific and technical expertise that university cooperators can provide to the NCSS.

The university representatives are responsible for coordinating AES responsibilities with the NCSS in their representative states. NCR-3 meets annually. On alternate years it meets with all NCSS members in the NCR to identify and coordinate research needs that support development of soil survey. Information on pertinent research being conducted at participating AES is exchanged among NCR-3 members. Three members of the NCR-3 committee serve on the Regional Soil Taxonomy review committee which reviews all proposed modifications to Soil Taxonomy including those developed by international working committees. Representatives from NCR-3 serve on NCSS work planning boards and national committees. These various committee linkages provide a network for evaluating soil survey technology in terms of its suitability for use in solution of current and anticipated land use problems. SSI is a major mechanism for technology transfer of research findings developed at AES and other research facilities in the NCR. Policies of NCSS are evaluated by the NCR-3 with respect to their impact on land users and AES within the region.
In summary, NCR-3 provides a forum for contributing to the scientific foundation that guide collection of SSI and its interpretation and extrapolation. It provides a mechanism for evaluating and refining NCSS directives to suit local and state needs within NCR, which is facilitated by participation of committee members on national committees of the NCSS.
As numbers of soil scientists and supporting resources have declined, the importance of a regional committee has increased. The meetings are an important forum through which research and extension initiatives are developed and the needs of society in general for soil and water information are identified and discussed. The university members on the committee are educating the next generation of soil scientists, and if societys needs are to be met, future pedologists must have a wider range of skills and perspectives than their predecessors.

Educational Plan

Traditionally, much of the outreach education of this committee has been indirect, largely through publications from the Natural Resource Conservation Service (NRCS), formerly the Soil Conservation Service (SCS), and University Extension.

1. Produce educational soil interpretation materials for specific land uses, including agronomic and silviculture, on-site waste disposal, wetland identification, soil erosion control and tillage management, and understanding the temporal and spatially variable attributes of soil systems. These guides will explain cause-and-effect dynamics as well as providing information for interpretations.

2. Produce web-based educational models that focus on soil-water dynamics, soil erosion, and the synergisms among soils, landforms and living organisms.

3. Develop educational materials for use in grades K-12 with the intention of making science more relevant, interesting and accessible to children and their teachers.

4. Continue to produce soil maps at a variety of scales and continue to provide information to ancillary agencies (NRCS and state groups such as Departments of Natural Resources and Departments of Conservation) for use in their educational outreach programs.

Organization/Governance

The committee will adopt the multi-state standard governance with the election of a chair, a chair-elect, and a secretary. All officers elected will serve two-year terms to provide continuity.
