Welcome: Dr. Randy Brown, Chair of The Department of Soil and Water Science

Dr. Brown provided an overview of the geology and soils of Florida and the programs of the University of Florida. He discussed a research delivery model that is being used to secure adequate funding for research and extension programs. Funding Formula: RDU = (DM x DW) / 40. Thrust areas of the University of Florida Soil and Water Science include the following: 1) Nutrient, Pest, and Water Management, 2) Soil landscape analysis, 3) Remediation of contaminated soils, water, and aquifers, 4) Wetland Systems, 5) Soil Quality and Ecological Indicators.

Administrative Reports: Dr. George Kriz, Dr. Wayne Jordan, Dr, Maurice Horton

Dr. Kriz indicated he will be retiring Oct. 31, 1999 and stated that Dr. Scott Smith, of the University of Kentucky, will replace him. He stated that it had been a pleasure to work with the group and reviewed accomplishments. There have been 11 publications to date (see attached). The following recommendations concerning publications were made: 1) Recommend that we place all old publications on our Web Site, 2) Recommend that there be a process for updating old publications. The Southern Directors will address and act on these issues.

Dr. Kriz indicated that SERA-IEG-6 has been approved (see attached) for the next 5 years and reviewed the three primary objectives 1) To develop, modify, and document reference laboratory procedures for nutrient analysis labs in the Southern Region, 2) To "regionalize" soil test calibration/correlation and interpretation efforts among states that share similar soils and climate. 3) To encourage analytical proficiency and adequate quality control/assurance among member laboratories. He also emphasized the importance of the group as we address phosphorus and other water quality issues in the future.

Dr. Kriz was presented a certificate of appreciation from the group for his guidance, leadership, and support during his years as administrative advisor. Drs. Jordan and Horton further commented on Dr. Kriz’ unwavering support over the years.

Dr. Jordan indicated that he did not have anything specific to report to the group but that he would continue in his administrative role as advisor to the group as long as it was needed.

Dr. Horton gave a brief overview of recent program changes in Washington and their predicted impacts on research and extension activities.

Topics of Discussion:

What’s ahead in the P arena? SERA-17 Programs and Activities, Dr. Steve Hodges

Steve’s presentation (see attached copy of slides) pointed out that previous assumptions concerning phosphorus are now being questioned: 1) P does not leach, 2) Soils have an infinite capacity to retain P, 3) If we stop erosion, we also stop P movement, 4) There are no problems with P in our estuaries, 5) What are acceptable concentrations of P from agricultural fields? The bottom line message of Steve's remarks was that we should not limit P rules to soil test P level!

A lengthy discussion followed in which Charles Mitchell, Leon Young, Tony Provin, and Bill Thom gave reports from activities in their states. The discussion ended with SERA-IEG-6 agreeing to develop a resolution to be sent to NRCS and other appropriate groups voicing concern over the current misuse of soil testing to establish phosphorus impact on the environment. A small group of participants put the resolution together and it was approved the next morning. (Click here for the final copy of this resolution.) Dr. Jerry Kidder offered a second resolution (see below) to be reviewed by the committee and sent to appropriate Directors of Research and Extension in the Southern Region along with copies to Agronomy News and other journals as deemed appropriate to make the need for additional research known throughout the US.

Routine soil testing methods for phosphorus have been developed for decades and have been calibrated using agronomic parameters, primarily crop yield or similar performance measures. The SERA-IEG-6 group and its predecessors, which represent many years of professional work in soil testing and calibration, wishes to express serious reservations about inadequately researched efforts which attempt to interpret such P soil test results in terms of potential for causing environmental damage. We urge that research continue to be supported which would lead to development and calibration of environmental P tests.

Both resolutions were unanimously approved for further refinement and action by the chair according to directions of the group.

Committee Reports:

Dr. Ray Campbell - "Reference Sufficiency Ranges for Plant Analysis in the Southern Region of the United States". Approval has been received from the SAES Directors for placing the publication on the Web. The Editorial Committee will review the format and make final suggestions after which this will take place. The publication will be considered a "work in progress" and additional crops will be added as they become available. Ray Campbell expressed appreciation to members for their assistance and patience in getting the publication completed. Members will be informed when the publication is available on the Web by e-mail.

Laboratory Report:

Dr. Jim Bartos, University of Florida - Jim showed a video and gave a summary of activities over the past couple of years that have greatly improved efficiency and performance of both the Extension and Research laboratory services (see attached).

North Central Region Report:

Dr. Doug Beegle (see attached) - In 2000, NCR 13 will host the joint meeting. Locations and times for the meeting were discussed. The SERA-IEG-6 group recommends that NCR 13 consider meeting at Penn State as first choice and Indianapolis as second choice. Prefer to meet between June and September.
