Delivery of Technical Soil Services

Duties and functions (604.00)

The Technical Soil Services program is dedicated to providing leadership and assistance in all aspects of soil data collection, interpretation, application, and presentation and in the integration of this data with other natural resource information for sound resource management by internal and external customers.

These services 1) identify and address soil survey information needs and opportunities within NRCS and the National Cooperative Soil Survey (NCSS); 2) help users to understand what soil survey information is relevant and how to integrate that information into their technologies and applications; 3) obtain feedback that helps to identify the need for additional research or additional soil survey information; 4) provide training to NRCS field staff and external customers on the variety and use of soils information and training that helps soil scientists to carry out their assigned duties; 5) provide soils information that meets NRCS policy and program needs, such as the Environmental Quality Improvement Program (EQIP), the Farmland Protection Policy Act (FPPA), the Food Security Act, and the NRCS Field Office Technical Guide (FOTG); and 6) facilitate the implementation of other agency programs and policies, such as wetlands programs, Land Evaluation and Site Assessment (LESA), and the Clean Water Act.

One can readily visualize from the extensive list of activities identified above that the demand for the time and skills of resource soil scientists is extremely high. In 1999, the Soil Survey Division conducted a review of the needs for technical soil services within the NRCS. The data were collected by telephone interview in June of 1999 by six soil scientists, each assigned a different region of the country. These interviews were with 42 resource soil scientists and 34 interdisciplinary NRCS employees, including agronomists, soil conservationists, biologists, foresters, and range conservationists.

Two broad categories of recommendations were summarized. The first pertained to technical issues, such as making soil survey information more accessible to users, providing access to different kinds of data, recording collected field data, providing new soil interpretations, sharing of data, data reliability and risk analysis, and data products and delivery.

The second category of recommendations was related to day-to-day operations and management. Concerns included additional training needed to do the job and the ability to report Technical Soil Services accomplishments. For many years the number of acres mapped by production soil scientists has been the major product reported to management and Congress by the Soil Science Division of the NRCS. Resource soil scientists were isolated and stretched too thin by their workload, and their position classification and grade structure needed to be updated to reflect current responsibilities.

Resource soil scientists are widely recognized by USDA agencies and other Federal agencies, State governments, and local governments, including Soil and Water Conservation Districts, for providing excellent soils assistance to field office staff and other customers. A National Soil Survey Program Evaluation in December of 1997 showed that field conservationists were highly satisfied with the quality, timeliness, and understanding of technical soil services provided by NRCS soil scientists.

Opportunities for resource soil scientists (604.02)

The soil survey information of the National Cooperative Soil Survey is the most detailed and comprehensive natural resource information available in the United States. Soil scientists are using soil survey information for an increasingly diverse array of applications that go well beyond the traditional use for agricultural planning and management. The increased interest in soil survey information reflects the diverse and sometimes competing options that are proposed or implemented for the use of natural resources. These options include broad social concerns about overlapping issues, such as resource sustainability; global climate change; soil, air, and water quality; biodiversity; and environmental protection. Resource soil scientists are challenged to formulate soil survey information in a sufficiently robust and reliable manner to meet existing and emerging applications.

Geographic Information Systems (GIS) and allied technologies for organizing existing soil survey information have emerged as powerful tools available to resource soil scientists. Much of the current soil survey information, however, has been prepared over a span of 45 years. Changes in scale, cartographic techniques and technology, landscape concepts, land use interpretations, and classification systems have occurred during this time. As a result, technical problems and concerns about data quality should be addressed before data can be reliably incorporated into automated systems. Automated technologies also provide a means of improving the amount and use of information contained on soil maps and in their associated databases through application of spatial, analytical, and display techniques. Electromagnetic induction meters and better quality low-level imagery satellites, with improved resolution, have high potential for useful applications. Digital elevation models provide data that will improve our understanding of soil-landscape relationships for onsite investigations. We need to use new soil technology information critically, and we need to ensure that the technology deals with an appropriate content. Deciding just what is and what is not correct content is a task for the intelligent soil scientist, the information specialist, and others working together as a team.

Consulting soil scientists are major suppliers of technical soil services in the private sector. The National Society of Consulting Soil Scientists, Inc., is a growing organization. The consulting soil scientists provide a wide variety of soils information to private industry. They have done extensive work in wetland assessment, land valuation, onsite investigation for urban development, environmental assessment, site-specific management, and other areas. They use the technical and quality standards of the National Cooperative Soil Survey in preparing “order one” soil surveys and interpretations.

The work of resource soil scientists, as well as that of soil survey production soil scientists, must be guided by sound scientific theory. We shall never really know enough about a soil because we will always be trying to sharpen our predictions and include new and innovative alternatives. It is through a series of approximations that we progress toward truth. Agricultural development, urban expansion, environmental degradation, global climate change, and natural resource economics offer a wide range of challenges and opportunities to create or mobilize soils information.

The role of soil scientists who provide technical soil services has been firmly established. As all soil surveys are digitized and soil survey information is more easily accessible to users, the general public will need increased assistance from competent soil scientists in effective use of this vast store of complex soils information. The future of resource soil scientists is exciting and challenging. Soil scientists working in technical soil services will lead and market the continued long-term success of the National Cooperative Soil Survey.
